I went ahead and created another separate UV paint texture so I could make my rivets brassy. That worked out great. However, I wish that I could make my black/gray brackets very slightly metaliic. I guess there's no way to do that now that it's in there together with the wood? Maybe this is a dumb question. This part of blender is new for me.
I see. I think there is more on this in the next sections of the tutorials maybe, too.
That's where I am BTW. Yeah. My lock is quite different. It actually has a slot in the top where a tooth from the top rim fits in when the chest closes.
