General information

Full name: "Autodesk Softimage Mod Tool". Usually we just call it "Mod Tool" or "XSI" (old name of the program).

Beside the free version, there's also the retail and student version "Autodesk Softimage [year]"

2015 is last version. Autodesk's development will focus on Maya and 3ds Max.

Those versions are also available as 64-bit versions.

But in the very most cases "Mod Tool" is enough to modify Oni.

There's also the possibility to get files that extent Mod Tool's range of functions.

Those are scripts (.vbs, .js), toolbars (.xsitb) and addons (.xsiaddon).

They can be created on one's own and also shared with other users.

Wanted knowledge:

How to setup particle in Mod Tool? We still need an Oni particle editor!
How to rig models and then extract the animation data?
How to make complex new UV-maps?

how to bind scripts to buttons (embedded code or .vbs / .js)

You can enable/disable the Main Shelf over "View" > "Optional Panels" > "Main Shelf". Then click the "Custom" tab.
A) Right-click the free gray space, click on "Customize Toolbar...". Select "Toolbar Widgets" > "Script Button".

Enter your code and make sure you selected the correct Scripting Language. Click okay when you are done.

B) You can also drag'n'drop your script file directly onto the free gray space.

A new window pops up, check the settings and click okay when done.

Right-click the Main Shelf and use the "Save" option. ("Save As" let you save the Main Shelf as toolbar file.)

how to install toolbars (.xsitb)

creation: goto "View" > "New custom toolbar"

Now you can add buttons like in Main Shelf. Remember to save your changes. (Right-click, "Save As".)

installation: Drag'n'drop the xsitb file onto the viewport (it's simply the window where you can see 3D objects).
access: goto "View" > "Toolbars"
deletion: goto "View" > "Manage..." Check a toolbar and click Delete button.

The file will remain with a new file suffix ".bak" You can restore this backup if you remove the ".bak" from the name.

how to install add-ons (.xsiaddon)

A) drag'n'drop the file into the so-called viewport (it's simply the window where you can see 3D objects), then restart Mod Tool
B) if drag and drop doesn't work, goto "File" > "Add-On" > "Install"

Then click on the "..." button to search for the file. When you found it, click the "Install" button.

building add-ons (http://softimage.wiki.softimage.com/sdkdocs/cus_addons_WalkthroughBuildinganAddon.htm, dead link)

Building an add-on file needs more effort than the other 'extensions' but for the end user it's best because it can hold all other files: toolbars, plugins (scripts), etc.
- The user can install a newer version of the addon by repeating the installation with the new file: it's unnecessary to remove the old version.
File > Add-On > Package... doesn't work with ModTool "Add-Ons cannot be created with Softimage Demo Version."
Images and any other files can be put into any folder of the add-on.
- Let's say you have an addon called "my_stuff", a subfolder "images" and an image called "test.png". The image can be accessed via:

XSIUtils.ResolvePath("$XSI_USERHOME/") & "Addons\my_stuff\images\test.png"

The problem with embedded code: commands like CreatePrim can call an property page (PPG).
- Those popups can be disabled. Search for "disabling PPG popups" on this page.
Putting scripts simply into folders doesn't work, they must be "plugins", the file extension can be the same e.g. "vbs".
- A script function can run on another computer if it is found as command, and plugin register new commands.
- E.g. you can use those commands in your toolbar's script buttons.
Example of turning a function into a command:

function with arguments as it is

' this function can only be used inside the script where it was defined

function simple_math (a, b, operator)
	if operator = "+" then
 		simple_math = a + b
	elseif operator = "-" then
		simple_math = a - b
	elseif operator = "/" then
		simple_math = a / b
	elseif operator = "x" then
		simple_math = a * b
	else
		logmessage "The used operator is not allowed. Choose one of the following:" & vbCrlf & "+ - / x"
	end if
end function

' example of usage
result = simple_math(5, 3, "+")
logmessage result

the same function as command

' the command simple_math can now be used in any script

function XSILoadPlugin( in_reg )
	in_reg.Author = "your_name"
	in_reg.Name = "simple_mathPlugin"
	in_reg.Email = ""
	in_reg.URL = ""
	in_reg.Major = 1
	in_reg.Minor = 0

	in_reg.RegisterCommand "simple_math","simple_math"
	'RegistrationInsertionPoint - do not remove this line

	XSILoadPlugin = true
end function

function XSIUnloadPlugin( in_reg )
	dim strPluginName
	strPluginName = in_reg.Name
	Application.LogMessage strPluginName & " has been unloaded.",siVerbose
	XSIUnloadPlugin = true
end function

function simple_math_Init( in_ctxt )
	dim oCmd
	set oCmd = in_ctxt.Source
	oCmd.Description = ""
	oCmd.ReturnValue = true

	dim oArgs
	set oArgs = oCmd.Arguments
	oArgs.Add "a",siArgumentInput,"0"
	oArgs.Add "b",siArgumentInput,"0"
	oArgs.Add "operator",siArgumentInput,"0"
	simple_math_Init = true
end function

function simple_math_Execute( a, b, operator )
	' convert to double
	a = cdbl(a)
	b = cdbl(b)
	
	if operator = "+" then
		simple_math_Execute = a + b
	elseif operator = "-" then
		simple_math_Execute = a - b
	elseif operator = "/" then
		simple_math_Execute = a / b
	elseif operator = "x" then
		simple_math_Execute = a * b
	else
		logmessage "The used operator is not allowed. Choose one of the following:" & vbCrlf & "+ - / x"
	end if
end function

Selected wisdom

We've also a tutorial thread on OCF.

Hotkey list can be found here.

Visibility

show/hide grid: [G]
display polygon normals: click the eye symbol, select "Polygon Normals" (now you know the polygons up and down)
display triangle count: click the eye symbole, select "Selection Info"

Camera navigation

reset view: [R]
zoom camera: [Scrolling]
move camera: [S] + [LClick] + [MoveMouse]
rotate camera: [S] + [RClick] + [MoveMouse]
pan camera: [S] + [MClick] + [MoveMouse]
move camera mode: [Z]
rotate camera mode: [O]
pan camera mode: [P]
use camera mode move/rotate/pan with: [LClick] + [MoveMouse]

Mesh

scale mode: [X]
rotate mode: [C]
translate mode [V]
manipulate tool: [B] (a gray box appears with gray balls at the corners)
- drag inside the object to move it
- drag an edge to rotate it
- drag a ball to scale it
object selection mode: [Space]
extracting a polygon from an object: select polygon, right-click, "Extract Polygons (Delete)"
copying an polygon from an object: select polygon, right-click, "Extract Polygons (Keep)"
merging two objects: select object A, then goto Model > Modify > Poly. Mesh > Boolean > Union, select object B

(this makes a copy of object B and attaches it to A, the merged objects (A) must be freezed before the original object B can be removed)

filling a hole: select all edges surrounding the hole and choose one of the following methods
- A) goto Model > Modify > Poly. Mesh > Weld Boundary Points/Edges
- B) goto Model > Modify > Poly. Mesh > Bridge Boundary Points/Edges (if blue lines appear try to disable the checkbox "Angle > 90")
merging two objects at blue lines: merge the objects at first, then proceed with the point above "filling a hole"
merging two objects with UVs: Create > Poly. Mesh > Merge
- extracted Oni characters have their materials and hence textures directly grouped under the mesh (see Explorer)
- when adding (merging) a new part to the existing mesh, the materials/textures will be grouped under (Explorer again) mesh > Polygon Mesh > Clusters > ...
- Samer reported that saving the file via fbx solves a problem when trying to convert TRBS
- one would need to move the content by hand in the explorer to bypass the fbx
hiding some objects/polygons: select object/polygon and hit [H], use [Control] + [H] to unhide all
mirroring an object: select object, Modify > Poly. Mesh > Symmetrize Polygons
working with symmetry mode (look below at "Low poly modeling" section for other possibilities with symmetry)
- select object, Property > Symmetry Map (YZ/XZ/XY) (press [W] to preview symmetry plane)
- click on Sym buttom (in Transform area) to enable/disable symmetry mode
- changing the Symmetry plane: Explorer [8] > unfold object > Polygon Mesh > Cluster > delete SymmetryMapCls; then add a new symmetry plane

Low poly modeling

select edge loop: while being in selection mode Edge, press [Alt] + [MClick]
modify point/edge/polygon: [M]
- press left mouse button and hold it, move mouse to translate point/edge/polygon freely

if axes symbol is active you can left-click a component and the translate axes pop up

if magnet symbol is active the translation will be limited by the surrounded components

if point symbol is active then only points can be selected, moving one point onto another will weld them

By the way, combining edge loop with component selection [M] and active magnet gives an interesting effect: a line of edges will mimic the shape of their neighbor edges as closer the selected edges comes to the neighbors.

getting images into Mod Tool that serve as modeling reference:
- click where you can set the view mode (e.g. to "Wireframe"), select "Rotoscope"
- in the appearing window at "Image Placement" choose "Fixed" so that the image will be zoomed when you zoom on the object
- choose an image by clicking the button "New"

symmetry in modeling:

You could make A) only one half of an object or B) selected polygons and then mirror and merge the parts.

A) select object, [Alt] + [RClick] object, Symmetrize Polygons
B) select polygons, [RClick] one of them, Symmetrize Polygons

Or you start with a half object and create a mirrored clone. You can then work on the original mesh. (In Schematics the cloned mesh will have a red "Cl" and a trapezoid shape as symbol.)

select object then goto Edit > Duplicate/Instantiate > Clone Single
scale X or one of the other axes to -1
make any modification on the original mesh, the clone will adept them
eventually merge cloned and original mesh, freeze them to make changes final

Exchange meshes in hierarchies

Let's say you loaded an Oni character with his 19 body parts into the scene, something is wrong and you want to fix it.

To destroy the hierarchy you must be sure the model is not animated. If there are keyframes the model will be one big mess after breaking the hierarchical links.

So, save the model with the settings "Selection Only [X]" and "Animation [ ]". Then reload the model.

Next, disable the red "Auto" button under "Animation" (if enabled). Keyframes affects also the creation of hierarchies, that's why we don't want new keyframes.

Now you can safely exchange, move and rotate meshes and their centers, and eventually rebuild the hierarchy.

Material and texture

how to apply a new main texture

how to apply a new polygon cluster texture

objects use the scene material by default, objects need their own material if they should have individual textures
selecting a material and surface: Model > Material > Phong (simply close the windows that pops up)
connecting the texture with the material:
- [7] to open Render Tree
- in first column: "Texture"
- in second column: drag'n'drop "Image" into the free space
- click and hold the red point of "Image", then move it to "Phong" and release the mouse click
- choose "diffuse" as illumination mode (for instance "ambient" won't work - the texture would be visible in Mod Tool but Onisplit can't use it)
now "Image" can be double-clicked (the Texture Editor will pop up), in the section "Image" click on "New" to choose an image
to change textures don't drag and drop textures directly one meshes, this creates textures layers which are ignored by OniSplit

Projection and UV

getting started

in section "Texture Projection" click on "New", choose a projection similar to the mesh shape (planar / cylindrical / cubic / spherical)
select the object
Texture editor: [Alt]+[7] (open it while being in selection mode "Object" or "Polygon", otherwise the UVs aren't shown)

modify single/all UVs

rotate 90°: [R]
rotate: [C]
scale: [X]
scale height only: [X], then [Shift] + [MClick] + [MoveMouse]
scale length only: [X], then [Shift] + [RClick] + [MoveMouse]
move: [V]
tearing single UV parts: [Control] + [T], then move [V]
heal (re-connect) selected UV parts: click on the plus symbol (the parts should be very near to each other, best if the points are on same spot)
snap function for move tool: Snap > Enable Snapping; check "Points" (if not already active)
relax (smooth warped UVs): [Control] + [R] (usually pressing several times that combination)
a new projection can also be applied to currently selected UV parts
freeze object to bake projections (green lines in the 3D view will disappear)
getting a picture of the UV: apply first a black texture then enter the Texture Editor [Alt] + [7], Edit > Stamp UV Mesh [Shift] + [S], save the texture

Rendering

Rendering doesn't work well on my PCs.--paradox-01 (talk) 01:09, 9 March 2016 (CET)

Especially PNG, it works one time. But as soon as I import another dae the next render will fail.

So, for creating a object library we might use blender. Nice thing is, it can also render in the background when called from CMD. This means you could keep working in XSI and render images in blender at the same time.

example of a batch file:

cd C:\Program Files\Blender Foundation\Blender
blender -b --python C:\Users\Paradox-01\Desktop\blender-out\pythonScript.py

example of a render script:

import bpy

# delete blender default cube object
bpy.ops.object.mode_set(mode='OBJECT')
bpy.ops.object.select_by_type(type='MESH')
bpy.ops.object.delete(use_global=False)

# load new object
bpy.ops.wm.collada_import(filepath = "C:/Oni/r.dae")

# render settings
bpy.data.scenes['Scene'].render.resolution_x = 900
bpy.data.scenes['Scene'].render.resolution_y = 900
# default resolution percentage seems to be 50 
bpy.data.scenes['Scene'].render.resolution_percentage = 100
bpy.data.scenes['Scene'].render.use_antialiasing = True
# 5 | 8 | 11 | 16
bpy.data.scenes['Scene'].render.antialiasing_samples = "8"

#TGA IRIS JPEG MOVIE IRIZ RAWTGA
#AVIRAW AVIJPEG PNG BMP FRAMESERVER
#no gif ? could be created by more code, maybe merging single frames of jpgs
bpy.data.scenes['Scene'].render.image_settings.file_format = 'JPEG'
bpy.data.scenes['Scene'].render.image_settings.quality = 100

# file suffix is overwritten by file_formate
#bpy.data.scenes['Scene'].render.filepath = 'C:/Oni/renders/test.jpg'
bpy.data.scenes['Scene'].render.filepath = 'C:/Oni/renders/test'

# start render
bpy.ops.render.render( write_still=True )

Animating

an animation that got scaled down from 116 to 58 frames

preparing ModTool to save animations Oni can use: File > Preferences... > Preferences > Tools > Output Format
- Frame Step: 1
- Frame Format: Custom framerate
- Frame Rate: 60
for real-time playback click on "Playback" option button and then "Real-Time Playback"
opening the Animation Editor : [0]
opening the DopeSheet: from any other Animation Editor, Editor > DopeSheet
making an animation shorter or longer: in DopeSheet click Region button (arrow with rectangle), click and hold to select keyframes, at selection edge a) [shift] plus left-click and move mouse or b) middle-click and move mouse

Issues when saving and sharing animation files (.dae, .exp)

That what you currently see in Mod Tool and that what you get when saving data can be different.

1) *.dae files might save data differently than expected.

Rotation flips might appear.

2) *.exp and *.dae save data differently.

.exp files store the frames as they are.

.dae file store their actions (rotations/translation/...) in seconds and eventually depend on what framerate a Modder uses.

Following scenario: a modder wants to share an animation as *.exp and another modder wants to use that animation.

Modder A uses 30 fps in his settings and exports an *.exp that is 58 frame long.

Modder B uses 60 fps in his setting and imports the *.exp, to his surprise the animation is 116 frames long. What now?

If Modder B saves the *.exp under a new name would not help, the frames will be still the same.

Instead Modder B could scale the animation. The way to do so is described in the Animating section, "making an animation shorter or longer".

Modder B scales the animation and saves it as dae.

Now he wants to see if it worked. He opens a new scene [Strg]+[N] and loads the dae.

Summary of issue-holding aspects

Frames Per Second (FPS)

When you share *.dae files with other Modders be sure that the output formate is 60 fps. Different framerates among modders can cause confusion.

Dae file store their actions (rotation/translation/...) in seconds.

An example:

<float_array count="10" id="pelvis_rotation_x_ANGLE-anim-input-array">
    0.000000 0.166833 0.333667 0.500500 0.600600 0.934267 1.267933 1.601600 1.768433 1.935267
</float_array>

action at [s] * framerate [f/s] = frame [f]

In this example the last rotation occurs at 1.935267s.

Modder A uses 30 fps, his last frame is 58.

Modder B uses 60 fps, his last frame is 116.

Euler rotations

you will get BEZIER (cubic) interpolation instead of LINEAR if you use

"Convert Quarternion Rotation to Euler"

"Spline Interpolation" in the animation (fcurve) editor

Those smooth the rotations.

[...]

Quaternion rotations

Don't use this.

[...]

Make Rotation Keys Continuous

[...]

Animation mixer

This could help with creating cutscenes and complex animations (e.g. run cycles for FILM files).

Open the animation mixer with [Alt]+[0].

Further information over HERE.

Here are a few videos:

Sounds

Within the animation mixer also sounds can be added.

Further information over HERE.

This could be used to synchronize sounds effect with physical actions in the scene.

Scripting

open the Script Editor: [Alt] + [4]
run the current code in the Script Editor window: [F5]
clear the log: Edit > Clear History Log
Actions from button embedded code will be logged.
Actions from code files that are linked in a button won't be logged. (This results in a performance boost.)
Logged stuff will be rewritten if you change the script language. (File > Preferences...)
You can also change the language by right-click the white script box and click on "Set to JScript" or "Set to VBScript".
Python can be added as script language if you install it on your PC.
Right-clicking the white script box gives you also access to a few code piece, e.g. "Syntax Help" > "If..Else" or "Catch Error".
Mark code you want to disable ("Comment Out") or enable ("Comment Remove").
You can save your code to a file via "File" > "Save As..." or "Save Selection"

Notes about polygon extraction

a grid of 9 polygons (ID 0 to 8)
you extract the middle polygon (ID 4)
grid's polygon of ID 8 will change to ID 4
if you now extract 5th, the 7th gets the ID
now the ID order is: 0, 1, 2, 3, 6, 5, 4
this means that an automatic extraction of several polygons requires two changes in the code
1) the ID array of selected polygons must be sorted
2) the extraction must start with the last ID to avoid ID shift during the process (see code pieces)

Some basics of VBScript

In VBS you declare variables only as a variant e.g. "dim PolygonCount". Mod Tool decides what type it becomes when it uses the variable the first time.
You can put "option explicit" at the start of your script. Then you will be forced to declare all variables with "dim". That looks quite unnecessary but help to find mistakes for example if you mistyped a variable somewhere in a long script.

The commands are not case-sensitive, e.g. you can write "LogMessage" or "logmessage".
Vbs functions can be found HERE.

' while it is possible to use + in strings,
' you should actually use & only for strings
' and + only for numbers

logmessage "How about ... " + "a riddle?"
logmessage "Where can you find following phrase in Oni? " & "The day is mine !!"
logmessage "Did you know that Bungie likes to hide sevens? The digits of the year 2032 add up to " & cstr(2 + 0 + 3 + 2) & "."

' INFO : How about ... a riddle?
' INFO : Where can you find following phrase in Oni? The day is mine !!
' INFO : Did you know that Bungie likes to hide sevens? The digits of the year 2032 add up to 7.

More tips

You can replace each "logmessage" with a variable. In that case don't forget the = sign.
Selection(0) means that from all selected objects the first one is taken.
Use a loop to get all objects.

for each n in selection
	logmessage n
next

In order to shorten the code you might want to set script objects.

The command to create a standard cube is CreatePrim "Cube", "MeshSurface"

If you use set name = the cube or other object will be available under that name.

Then you can use any valid method or property with that name.

Example:

set c = CreatePrim ("Cube", "MeshSurface")

logmessage selection(0).name
logmessage selection(0).length.value
logmessage c.name
logmessage c.length.value

' INFO : cube
' INFO : 8

Some ModTool commands in vbs language that might be interesting for Oni related stuff

LogMessage [string \| var \| object]	A command to log information. It requires a string or a variable. Example: LogMessage "The object's name is: " & selection(0).Name
logmessage selection.count	Logs the number of selected objects.
logmessage selection(0).Name	Logs the object name.
logmessage selection(0).Materials(0).Name	Logs the material name.
logmessage selection(0).Materials(0).Library.name	Logs the material library name.
logmessage selection(0).Materials(0).shaders(0).name	Logs the material shader (e.g. phong).
logmessage selection(0).Materials(0).CurrentImageClip.source.filename.value	Logs absolute path of the texture. Output example: C:\Users\RRM\Desktop\TV_tex.png
logmessage selection(0).Materials(0).CurrentImageClip.source.Parameters("XRes").Value logmessage selection(0).Material.CurrentImageClip.source.Parameters("YRes").Value	Logs the horizontal (X) and vertical (Y) pixel length of the texture. Output example: 512
logmessage selection(0).sclx.value logmessage selection(0).scly.value logmessage selection(0).sclz.value	Logs object's scaling (X, Y, Z).
logmessage selection(0).rotx.value logmessage selection(0).roty.value logmessage selection(0).rotz.value	Logs object's rotation (X, Y, Z).
logmessage selection(0).posx.value logmessage selection(0).posy.value logmessage selection(0).posz.value	Logs object's position (X, Y, Z).
logmessage selection(0).rotorder.value	Logs object's rotation order. Oni characters have ZYX as rotation order. 0 = XYZ 1 = XZY 2 = YXZ 3 = YZX 4 = ZXY 5 = ZYX
SelectObj [string \| var]	select one or more objects. Comma serves as separator. Example: SelectObj "grid,grid1"
ToggleSelection [string \| var]	Adds one or more objects from current selection. If the objects are already selected then they become subtracted from the selection. Example: ToggleSelection "grid2,grid3"
SelectAllUsingFilter [SelFilter], [CheckComponentVisibility], [AffectSelectionList], [CheckObjectSelectability]	Selects everything that matches the filter and other options. Example: SelectAllUsingFilter "object", siCheckComponentVisibility selects all roots, lights, cameras, and geometry (meshes) SelectAllUsingFilter "geometry", siCheckComponentVisibility selects all geometry (meshes)
DeselectAll	deselects everything
DeleteObj [string \| var]	Deletes one or more objects. Comma used as separator. Example: DeleteObj "grid" DeleteObj "grid,grid1"
FreezeObj	Makes all changes final. But saving those changes is still necessary. (Click on key symbol so it gets red.)

Important:

Mod Tool has its own drag and drop event handler for dae and xml file.

If we succeed in modifying and shipping that new file, we could finally trigger scripts with those files and process them.

The original file can be found at:

logmessage XSIUtils.ResolvePath("$XSI_HOME/") & "Application\DSScripts\Model.vbs"
' C:\Softimage\Softimage_Mod_Tool_7.5\Application\DSScripts\Model.vbs

A backup of the original file can be found here: https://dl.dropboxusercontent.com/u/139715/OniGalore/ModToolScript/Model.vbs (dead link)

There are two issues that can be fixed by modifying this file.

import of xml files created by onisplit
import of dae and xml files with relative path from a html page

Relative file pathes will be transformed to absolute pathes whereby an unwanted "file:///" is added.

A solution to is to transform the path again.

if instr(in_Filename,"file:///") = 1 then
	in_Filename = replace(in_Filename, "file:///", "")
end if

Following function is always triggered, so we will modify it.

sub ImportDotXSIProc( in_Filename, in_Parent )
	if instr(in_Filename,"file:///") = 1 then
		in_Filename = replace(in_Filename, "file:///", "")
	end if
	Set objFSO = CreateObject("Scripting.FileSystem<Object")
	FileExt = objFSO.GetExtensionName(in_Filename)

	if application.license = "Avid 3D" then
		SIImportDotXSIFile in_Filename, in_Parent
	else
		Set oFS = CreateObject("Scripting.FileSystemObject") 
		if oFS.FileExists(in_Filename) = True then
			if FileExt = "xml" then
				' is this an Oni xml file ?
		 		Set xmlDoc = CreateObject("Microsoft.XMLDOM")
				xmlDoc.Async = "False"
				xmlDoc.Load(in_Filename)
				if xmlDoc.selectNodes("Oni").length > 0 then
					logmessage "Oni xml file detected"
					read_xml "OFGA", in_Filename
				end if
				exit sub
			end if

The lines in red has been added.

[40] layers

how to access scene layers

To access scene layers switch from Main Control Panel (MCP) to Keying Panel/Layers (KP/L) and then click "Scene".

After the user became used to layers, they can help to organize work in a scene. This is especially interesting for some scripting tasks like getting TRGV/FURN data for xml files.

' get current layer

logmessage CurrentLayer

' create a new layer named "FurnLayer" if it doesn't already exist

	SetCurrentLayer FurnLayer
else
	SetCurrentLayer "Layers.FurnLayer"
end if

' get objects in FurnLayer and count objects
' exit sub if there are no objects
SelectMembers "Layers.FurnLayer"
if selection.count = 0 then
	MsgBox "No OFGA data found to export.", , "Export canceled"
	exit sub
end if

' if there are Furn objects
