Quote - > Quote - good leather and cloth for non-UV-mapped objs

I'm not doing that, so if that's what you're hoping for, forget it. A good UV mapping is required, i.e. the physical distance spanned by any given amount in UV space has to be the same. Boob sections cannot be stretched over the boob. Right angles must remain right angles.

I am truly astonished how many items do not have consistent UV spacing. Even new stuff from SM has really bad (almost pointless) UV mappings.

Cloth pieces are cut from real cloth, which is perfectly consistent in its arrangement of threads. If that's not how the UVs are set up, it looks like crap.

Sometimes, a partial solution is to import an obj geometry in Blender (keeping vertex order), open the UV window and select UVs-> minimize stretch (ctrl-V)... then resaving the object, again keeping vertex order.
