I’m working on a Guitar Hero style game, and was wondering if it’s possible to just have the one note model and apply the different color textures to that one model for better efficiency.
You can add several materials to an object, but as far as I know, It’s not possible to rearrange what polygons get what material in Unity
However, if you enter your modeling program (maya, 3ds max, blender), there you can assign certain materials to certain parts of a model. You’d have to do that and then import as .fbx to Unity
When you open the model in Unity, you’ll see it has several materials (or texture slots). These slots are the same as the ones you created in your modeling program. So drag your textures into the slots and it should work
Hope this helps =)
