I've edited Toy Bonnie's materials a bit more and I think I've pretty much nailed his textures. Obviously this isn't 1,000% 3ds Max accurate, but it's good enough for me.
I haven't yet been discouraged by my lack of node and porting skills and I'm glad. I'm still learning Blender nodes, and I like to do this stuff myself. I can use other people's assets, but it won't feel the same. I like to make nodes myself and will continue to.
When people make a Toy Foxy model and give it materials, the hook is always Withered Foxy's textures, or just the endo texture. This isn't right. It's like the endo texture but super reflective. It's reflective in the teaser image if you use your eyes and look.
