I can’t figure out how to use and export displacement maps and normal maps with my rock.obj in ZBrush. Can someone please pm me and help me through the process. There is no reason it should be this difficult to export a rock from ZBrush into Unity. Thank you
Sure it should be, zbrush is a sculpting program. You need to have a low poly version of your rock, but it still needs enough density to displace in unity, you also need to have a shader setup that accepts that displacement, usually in a game engine tho your relying on a normal map. Altho you could also fiddle with teselation.
You need to be able to bake your maps, texture, displacement etc in another program, zbrush does not bake anything for you.
Also note that zbrush can export to obj format.
