So I saw this program,smart bump it takes a photo and somehow makes a nice bump map form it anyways I can't find it and would like to turn a tile texture into a bump..
Could someone recommend(doesn't have to be smart bump) a free bump map program that works well for what I'm trying to do ? Also for tile grout I'm assuming I'll have to add a displacement map and a bump for the texture of the grout .
Right ?
