I've been quickly applying regular non-PBR textures to my mesh before changing it to "PBR Metallic Roughness" and using PBR Materials so people using old viewers can still see a textured product. Now I'm wondering if I am adding any image/rendering 'weight' to it by doing this. Just thought it would be nicer than them seeing blank white or wood, lol, but don't want to start a bad habit if it's not a good one.
