  1. For most models, auto generating is fine. Things that the player will frequently bump up against may need custom collision.
  2. If you are baking normal maps, you want to triangulated your meshes first. If you are using tiling normal maps, it doesn’t matter.
  3. I use the same packing as Substance, a RGB for the Base_Color, a packed RGB using R=Metallic, G=Roughness, B=AO. If you don’t need metallic for a particular model, you can use the metallic texture for anything else (generally masks).

  1. Making smart use of tiling textures can save memory and increase the texture resolution the player sees. Generally you’ll use both unique and tiling, sometimes both on one model.
