Okay, so I am using blender to create all of my assets. However all of the custom meshes that I use turn grey when I build the lighting. I have never experienced this issue before and I do have two UV channels. Also, I have made sure that none of the Uvs are overlapping. Can someone please tell me how to fix this because I cant make anymore progress, and I have a deadline by the middle of October. Please this is really important
