OniSplit
OniSplit, written by Neo, is an integral part of the Anniversary Edition and an essential modding tool on its own. It does the work of splitting and recombining Oni's data files. But it also does much more such as extracting and creating TXMP files and M3GM files.
Export/Import textures
To extract all the TXMP files:
onisplit -extract:png destination_directory_for_image_files level0_Final.dat
TGA and DDS are also supported using -extract:tga and -extract:dds.
To import image files:
onisplit -create:txmp destination_directory [options] source_image_file
where options can be
-nouwrap - set the "U wrapping disabled" flag -nowwrap - set the "V wrapping disabled" flag -format:bgr555 (or dxt1) for most of the stuff -format:bgr32 for skyboxes -format:bgra4444 for transparent/reflective stuff (in a couple of places bgra5551 is used but probably it's not big deal if bgra4444 is used instead) -genmipmaps - generate mipmaps if they are not already present in the source file and if the source file is not dxt1 compressed
Example:
onisplit -create:txmp imported -format:bgr32 -genmipmaps tga\concrete.tga
To batch process a folder of image files:
onisplit -create:txmp imported -format:bgr32 -genmipmaps tga\*.tga
source_image_file can be dds or tga. "Color indexed" and "black and white" tga files are not supported currently. Other image file formats (png, jpg, bmp, tif) may work depending on Mono/.NET support for them. onisplit will automatically prepend TXMP to the output file name if the source file name does not start with TXMP already.
For TXMP files that contain envmaps:
onisplit -create:txmp dest_dir -format:bgra4444 -genmipmaps -envmap:envmapname imagefile.tga
The envmap name can have the TXMP prefix but it is added automatically if missing.
Export/Import 3D models
M3GMs, ONWCs, ONCCs and now TRBS can all be exported (in OBJ file format):
onisplit -extract:obj dest_dir M3GMnotfound.oni onisplit -extract:obj dest_dir ONWCw1_tap.oni onisplit -extract:obj dest_dir ONCCbarabus.oni
Or for a total export:
onisplit -extract:obj dest_dir level0_Final.dat
Importing obj files:
onisplit -create:m3gm dest_dir TCTF_Shotgun.obj
For importing obj files the obj file must only contain triangles so when exporting a model from a 3D design tool it needs to be triangulated. If the obj file uses more than one texture then only one will be taken into consideration. If the obj file does not contain a texture or someone wants to use a different one then the texture name to be used can be specified with -tex option:
onisplit -create:m3gm dest_dir -tex:TCTF_Shotgun TCTF_Shotgun.obj
Just like in -envmap option case the texture name can start with TXMP but it is not required. Note that in both -envmap and -tex cases a .oni file is not created for the specified texture. The .oni file for that texture must be create separately.
For TRBS files
onisplit -extract:dae dest_dir level0_Final/ONCCkonoko_generic.oni
This will generate a ONCCkonoko_generic.dae collada file in the directory dest_dir plus the tga texture files used by the specified character.
onisplit -create:trbs dest_dir some_dir\ONCCkonoko_generic.dae
This will create a TRBSkonoko_generic.oni file in dest_dir
Blender's Collada importer/exporter is buggy and you need to add the options -noanim and -zup when extracting collada files for use with Blender:
onisplit -extract:dae dest_dir -noanim -zup level0_Final/ONCCkonoko_generic.oni
noanim prevents the export of the default idle animation. That's needed because Blender doesn't import animated objects correctly. -zup exports a collada file with a coordinate system where Z axis points up instead of the default (Y up). This is needed because Blender uses Z up but the importer gets it wrong and convert to something else.
