SporeMaster reads models from the OGRE3D mesh.xml format, and textures from S3TC-compressed (DXT5). Also note that texturing is somewhat limited – I haven’t really figured out how the different texture channels interact – and mesh-level animation is completely unsupported so far. So don’t expect the workflow to be completely smooth. This is still a very new development – literally the only parts mods in existence are my cheesy glasses and cube.
This makes it possible to add new parts for the first time. The new SporeMaster 2 has the ability to pack models and textures into the renderware 4 (.rw4) format used by the game to store parts.
