Here is a sword I’ve been working on. It has 5 different blade combinations, 3 different tsuka (handles), and 2 different tsuba (guards).
I’m happy with the overall design and the textures are OK, but I’m having some trouble with bump mapping. Specifically, a bit of text for the blade. I can get a positive bump to show, but I’d like a negative bump (like the text was etched or carved into the blade). I can’t seem to get it to work. For the positive bump maps, I’ve got white areas for the high parts, and when I try to use black for a negative bump, I get crap. And yes, I know the tsuka is non-traditional – the whole sword is actually.
Here is my node setup for the bump maps. Any help would be appreciated.
