Might be another crash.

Probably want to check if p_mesh_arrays is sized ARRAY_MAX and all the requirements like vertex array existing is good.

Should be fixed by dca566a. I'll try some more glb test meshes later cause haven't found a mesh triggering this. the ARRAY_MAX check and vertex_array existing check are directly in the format generator which will just return 0.
