Export
TRAM files can be extracted A) as pure XML files or B) as a pair of XML and DAE files. For editing the actual animation, you will want to use method B. While exporting an ONCC, you might see errors such as:
Cannot find instance 'TRAMKONCOMthrow_rev' Cannot find instance 'TRAMKONCOMthrow_rev' Cannot find instance 'TRAMKONRIFturn_right' Cannot find instance 'TRAMKONOKOlev18_ZomStand' Cannot find instance 'TRAMKONOKOcorner_hide' Cannot find instance 'TRAMKONPIScorner_hide'
Ignore them, as those files doesn't exist. (Someday we should remove them from the TRACs.)
Via command line
To export a single TRAM:
onisplit -extract:xml output_path -anim-body:path_to\TRBS_or_ONCCname.oni path_to\TRAMname.oni
To export merged TRAMs:
onisplit -extract:xml output_path -anim-merge -anim-body:path_to\TRBS_or_ONCCname.oni path_to\TRAMname1.oni path_to\TRAMnameN.oni
Via Vago
When you start Vago, the "General" tab should be open by default. If not, click on it. Then follow these five easy steps.
Step 1: Select "ONI" as input format ("From").
Step 2: Select "XML" as output format ("To").
Step 3: Check "Another TRAM" to chose a character animation file.
Step 4: Click "Add" button to choose an ONCC file.
Step 5: Click "Convert".
Via Simple OniSplit GUI
There was a long-standing problem with combined ONCC/TRAM files where the textures would be missing.
Simple OniSplit GUI post-edits the DAE to fix missing textures. The character-related .oni files must be all in one folder. Usually the level0_Final folder does the trick.
Step 1: Drag and drop TRAM and ONCC into the big field. (One by one or simultaneously; the order doesn't matter.)
Step 2: Hit "Convert".
Editing the actual animation
You can load the DAE file into a compatible editor. So far, the community's favorite is (formerly "XSI") Mod Tool.
- For the correct Mod Tool settings, see HERE.
Here are some hints for creating animations when there is no rigging available:
- Use the ONCC model in your 3D editor that is also intended for the animations. This makes sure the pelvis height will match and feet will not float in the air or go through the ground.
- First frame and last frame should match the probable previous and follow-up animations. This will reduce the necessity for long interpolations.
- When setting keyframes each body part should have been moved. This rule of thumb will give a more natural looking animation.
- The first body part to be animated is always the pelvis.
- Watch out for pelvis rotations so that the xyz rotations don't overlap too much otherwise you will get into a gimbal lock.

Extents and XML
Ever wondered how the AI can recognize incoming attacks and block or dodge them? Extents (found by geyser and fully uncovered by Neo) are the key. Imagine the character looked at from above, and visualize a circle with this character being at the center of the circle. Now divide this circle into 10° segments, and those are the 36 units of horizontal extents (that is, the lateral reach of the attack). The 0° point is directly in front of the character and 180° is behind the character. The segments run clockwise around the character. So the first Extent tag is the horizontal reach on the 0° line, the second tag is for the line 10° clockwise, and so on. Note that a frontal attack like a simple kick could hit a target not only if he's standing at 0° (directly in front), but also at 10° or 20° to the right, and also at 340° and 350° (a bit to the left). When setting these manually, you should guess the inner and outer ranges of the reach of the attacker's bones that have damage attached to them. Test these values with an AI that blocks often. If you did it right, your attack will often be blocked, but if the extent length is too high, the AIs will react when too far from you, which does not look good.
There are two types of extents:
- <Extents> stores this info:
- <Angle> at which this extent radiates from the character.
- <Length> of this extent.
- <MinY> minimal height of this extent.
- <MaxY> maximum height of this extent.
- Length, MinY and MaxY serve to create an invisible area in space which is "dangerous to be in". If an AI intersects with this area and notices it (refer to the Notice field in MELE), it will attempt to block or dodge according to its modifiers in its MELE profile (again, see the MELE page).
- The number of <Extent>s is equal to the number of attack frames: <End> minus <Start> plus one (because start frame counts too). For example, for TRAMKONCOMkick_low1: <End>30</End> minus <Start>22</Start> plus one = 9 <Extent>s.
- These extents are pretty impossible to guess, so leave them alone until Neo comes up with extent computation (probably from attack bones and bone rotations). However, always add at least one set of component tags, because those Length, MinY and MaxY components will be taken as the longest extent, the highest Y value, and the lowest Y value. Without those, a character won't react to this attack.
- <HorizontalExtents> stores this info:
- 36 fields (exactly 36, otherwise it won't compile back into a .oni file), which correspond to areas in 10° intervals around the character as described above.
Adding colorful trails
Open the XML-accompanied TRAM, search for the "Particles" tag, and insert your markup.
First example: TRAMSTRCOMcomb_p_p.xml
<Particles>
<Particle>
<StartFrame>0</StartFrame>
<EndFrame>12</EndFrame>
<Bone>LeftFist</Bone>
<Name>contrail</Name>
</Particle>
</Particles>
"contrail" is looked up by the character class (ONCC) that emits the actual particle; here it is "h2h_strtrail_e01".
This second example is about creating two different contrails in a TRAM at the same time. The animation is "TRAMSTRCOMpunch_heavy.xml".
<Particles>
<Particle>
<Start>0</Start>
<End>54</End>
<Bone>RightWrist</Bone>
<Name>contrail</Name>
</Particle>
<Particle>
<Start>0</Start>
<End>54</End>
<Bone>LeftWrist</Bone>
<Name>contrail_2</Name>
</Particle>
</Particles>
Note that you need to register the second contrail in the ONCC as well. Using your own contrail particle is also possible; just insert its name between the <Type> tags.
<ONCPParticle>
<Name>contrail</Name>
<Type>h2h_strtrail_e01</Type>
<BodyPart>-1</BodyPart>
</ONCPParticle>
<ONCPParticle>
<Name>contrail_2</Name>
<Type>h2h_murtrail_e01</Type>
<BodyPart>-1</BodyPart>
</ONCPParticle>
Adding extents to an existing animation
Let's say that you want to convert a non-attack animation to a damage-dealing animation. Non-attack TRAMs do not have extents information used to notify the AIs about incoming attacks, so how do you generate this information from the animation?
- 1. Export the animation to XML with a body attached. If you extract using just "-extract:xml dest_folder TRAMsomething.oni", you'll get the 3D animation data inside the XML (namely, the tags Heights, Velocities, Rotations, PositionOffset, and Positions; for an attack animation, you'll also get Attacks and AttackRing, and inside Attacks' elements, each Attack element will have Extents at the end of it).
- However, if you extract this same animation using "-extract:xml dest_folder TRAMsomething.oni -anim-body ONCCtramuser.oni", the animation data will be placed in a DAE file along with the character model geometry. Be sure to pick a body with a representative size for the character classes that will actually use this TRAM, because the extents will be calculated from it. The XML file will be very short without the 3D data in it. This is how we want the non-attack TRAM to look. We do not know the extents information that should go in Extents or AttackRing, so we just want to add the part that distinguishes a DAE-extracted attack TRAM XML from a DAE-extracted non-attack TRAM XML. That part is the Attacks section, without the Extents under each Attack.
- 2. First, consider whether the TRAM should have something added to its Flags section, like Attack or ThrowTarget.
- 3. Now add to the XML of the non-attack TRAM data in the following format (after the <SelfDamage /> section, typically):
<Attacks>
<Attack>
<Start>1</Start>
<End>10</End>
<Bones>RightWrist RightFist</Bones>
<Flags />
<Knockback>4</Knockback>
<HitPoints>10</HitPoints>
<HitType>KnockdownHead</HitType>
<HitLength>5</HitLength>
<StunLength>8</StunLength>
<StaggerLength>0</StaggerLength>
</Attack>
</Attacks>
- Do not add an AttackRing section after Attacks.
- 4. Import this with "-create dest_folder TRAMsomething.xml". The Extents sections and the AttackRing will be calculated by OniSplit from the attached DAE.
- 5. If you need this information for a patch mod, run "-extract:xml" on the TRAMsomething.oni you've created, without using "-anim-body". Now you can copy the Extents and AttackRing data to your XML patch. For an example of how the patch should look, see the Domino Knockdowns mod.
Throws
Throw target animations are registered in the TRAC of the throw initiator (AKA the throw source). Target animations are forced onto the other character, removing the need to have that animation in the target's TRAC. Throw target (TRAM*tgt) animations can cover only up to 256 (0-255) frames.
Forward throws
Scenario: you load two characters into Mod Tool and rotate (+/-180°) the throw target character because you need them to stand face to face as you work on an animation. When you are done animating, the target animation would need to be reversed again. This means multiplying the velocities by -1; the rotation also needs correcting. So it looks like you need *(-1) for the x rotation and -/+180° (depending on your initial change) for the y rotation.
Excel macro to tweak forward throws
- Here's the macro (for all TRAMs except overlays). Demo vid here. Usage:
- Put your files into the "input_and_output" folder.
- Disable macro security if you don't want to have to click on the macro options button every time.
- Close other worksheets before you run the macro.
- If you are not afraid of VBA code, you can enter the dev environment by hitting Alt+F11. If you want to extend the attack library with more screenshots and settings, search for: "LibraryThrows", " LibraryAttack", "Picture", and "CBAttackHelp.AddItem".
Run animations
Here's a breakdown of the Striker's run animations, meant as an illustration for what would be needed to make new run TRAMs.
Run cancel:
- STRIKEidle1 / another idle animation
- STRIKErun1stepa
- STRIKErun1stepb
- STRIKEidle1 / another idle animation
Run – a minimal cycle:
- STRIKEidle1 / another idle animation
- STRIKErun1stepa
- STRIKErunstart
- STRIKErun_rt
- STRIKErun_lt (optional)
- STRIKErunstop
- STRIKEidle1 / another idle animation
Follow the images below from right to left.

List of unused animations
Here are all the known unused animations. These could be reintegrated/recycled/whatever....
From the original game
- KONOKOconsole_punch: what the name says (the engine can use that animation depending on the console's configuration, see CONS)
- KONOKOlev3_intro: looks like she was placing something (bomb?) and then running away
- KONOKOlev4_undress: from an aborted clothes-changing cutscene
- KONOKOlev16_bomb: planting a bomb
- KONCOMsuper_kick: now used in OTA scripts (mod) as spawn event
- KONCOMsuper_punch: KONCOMpunch_heavy but without the shouted attack name, has HalfDamage flag, and does 10 less damage in its first attack part
- COMPISidle_special1: Comguy checking environment and his gun (meant for a feature that would visually depict an elevation in the AI's level of alertness after, say, hearing a noise)
- STRPISidle_special1: Striker checking his his gun and communicating with an ally (another unused alertness animation)
- THUGlev1_direct: Thug probably directing a truck driver
From modders
The following files are available in DAE (and maybe .oni format).
- Fury double flip (.dae)
- Konoko enters prone mode (.dae + .oni)
- Konoko leaves prone mode (.dae)
- These are artifacts of Paradox's work on his Prone Mode mod.
- Female stun (throw pair) (.dae)
- Needs to be slowed down by adding more frames.
Speeding up existing animations
s10k has created a XmlTools patch that allow the speedup of any existing TRAM (by removing frames). More information and download here.
Interpolation drifting
Issue
For unknown reasons some animations are unexpectedly interpolated.
So far this has been observed with transitions from idle to other animations (any attack or movement).
- chr_debug_characters = 1
- Use slowmotion cheat "carousel" or single step frame progression in developer mode for better visibility.
Normally, interpolations are encoded in TRAM files.
- Example in XML, KONCOMidle1:
<Interpolation>
<End>0</End>
<Max>65535</Max>
</Interpolation>
Despite the fact that idle interpolation is set to 0, ITO will always force an interpolation, most often it is 8 frames long.
Example in character debug display, KONCOMidle1 to KONCOMpunch_fw transition:
0/8 KONCOMpunch_fw 0/37
When you let the character perform an animation via command line or scripting the transition will not happen which makes us think that ITO interpolations behavior is hardcoded.
chr_animate 0 KONCOMpunch_fw
KONCOMpunch_fw 0/37
Proposed solution
To compensate this phenomenon you can add a Z position offset to the pelvis either manually or by script.
The offset would be applied to each keyframed Z position that is higher than 7 frames, if missing, create a Z keyframe at frame 8.
By changing the later positions by the same amount only the delta value of frame 0 to frame 8 will increase - compensating z translation ITO shortens.
ToDo
- create easy repeatable test setup
- determine type of interpolation (is it linear?)
- record and compare positions of each frame of ITO and programmatically played animation
- write script to alter the Z keyframes (8 to last)
- finetune the script if necessary by taking into account interpolation type
