Knobby: The chunk_pc file is a loadable part of the world. It is what is needed for a physical chunk of the world. This includes the level geometry, level collision, sidewalk data, traffic splines, world objects, textures, etc. I say etc, but it really is probably just the tip of the iceberg. This is a massive monolithic file full of all kinds of things.
sr2_chunk_extract_gmodels.py extracts obj from g_chunk
sr2_chunk_extract_materials.py extracts mtl from chunk
sr2_chunk_extract_texturelist.py extracts a list of textures used in the chunk.
sr2_chunk_replace_gmodels.py rebuild g_chunk from extracted models (and a very tiny bit of the old one).
Script usage:
python path/to/script.py path/to/chunkfile.chunk_pc
Use this to get textures: https://www.saintsrowmods.com/forum/threads/saints-row-2-chunks-texture-tool.12877/
Put textures to ./textures/ folder relative to mtl file.
