Zbrush Normal Mapping Issues
polycounter lvl 10
hey so i wanted to try out zbrush's new uv mapping function, and it's pretty cool.
a quick disclaimer this model is not mine, i just needed a topoed model with multiple subdivisions to test this. i can't recall who did it so forgive me.
anyway, i ended up making 4 normal maps for this guy because they were all coming out botched. i tried adaptive on, adaptive off, smooth uv on, smooth uv off. adaptive shouldn't affect anything, but i wanted to make sure. as i understand it, "smooth uv" tries to generate the map as if the low poly looked like the high poly, and attempts to compensate for the fact that it doesn't (particularly visible at sharp creases).
this seems to be the problem here, that it's not working correctly.
the creases aren't appearing on actual seams, so i'm pretty confused as to how to resolve this. please forgive me if this is a trivial issue
