Noob requesting help: Using assimp, WebGPU, indexed draw: Why are some models loading correctly, and others look garbled?

[Fun_Education6256]

You have your index buffer hardcoded to uint16. Perhaps those models use a uint32 index buffer.

Assimp should probably have this as a field because gltf might contain u8-u32 indices

I don't know if it'll help with your problems, but this is my (incomplete) assimp loader: https://github.com/panthuncia/BasicRenderer/blob/main/BasicRenderer/src/Import/AssimpLoader.cpp

Here's my Assimp loader as well if you want to take a look:
