Above image rendered with Unity 5. Guitar was modeled from scratch in Blender and textured in Substance.
Substance is amazing. It allows you to texture according to PBR standards ridiculously easily, as long as your mesh is well made. The coolest thing to me is the fact that I can easily texture different parts of the mesh with different “materials.” For example, the metal thingies are metal, while the body is plasti-wood. It all renders down to one material! The guitar itself is just one mesh! That’s amazing to me. It only adds one draw call to the scene. Now I see where all the PBR hype comes from.
