So me and E3po used some new deswizzle methods with some of the source from Alterations and released this tool that can rip models and bitmaps from both halo 3 and halo 3 ODST.
We don’t have all deswizzle methods so you will not be able to rip every single bitmap, but you are able to rip about 70%. Models are completely rigged with uvs as well as its markers.
Before the release I have been testing my HLSL skills by making shaders.
E:We are currently working on extracting sounds as well as BSPs. Sounds seem to use XNA compression so it should be easy.
