I purchased a model of a guitar from TurboSquid.com and I’m trying to apply my own custom shaders to it, and it’s working on some parts, but not others, and I can’t figure out why. I’ve been searching for the answer for 2 hours, and I can’t find it. I’ve updated to the latest version of blender (2.82) in case it was a bug, and nothing. You can see what I’m talking about in the attached link. I tried making a shader from scratch, and nothing appears. I tried making a shader using extreme PBR add-on, and nothing appears. I tried eevee, and cycles render, and nothing appears. It’s VERY frustrating, and I’m betting it’s a box that is check marked or something causing the problem.
What am I doing wrong??? Much appreciation for anybody who helps me solve this problem!
