Technical note

What changes when you convert OBJ to HPG

An OBJ model is often a set of files rather than one: the geometry in the .obj, its materials in a .mtl file next to it, and textures as separate images. The .obj on its own describes shape only, so copy the whole set together whenever colour and texture matter.
