uvs are changing?

ZBrush Usage Questions
#1

i made my uvs in max, exported them, made my uv check (with max texporter and in zbrush), even made test displacement maps with subd level 7 with a resolution of 2048 x 2048>> erverything worked fine.
but after several hours of work, zbrush showed me overlaps on the uv check texture and crashed everytime with dmaps over 1024 px.
i switched to my mt and remade my uvs with guv tiles, but making my clean max uvs, was nothing but wasting a lot of time .

zbrush is a great tool, but it is getting more and more annoying, cause it makes u spend half of your working time handling with export/import, uv and crashing problems.:confused:

ZBrush doesn’t change UV’s that are assigned to the model, so I don’t know what might be causing this to happen. When you calculated the map, were you using Adaptive or DPSubPix mode?

#3

i’m always using adaptive mode. strange thing is, that on the current subd level, there are no overlaps, just on the lower levels or the mt now.

#4

What steps are you following to assign the UV’s? Are you creating a blank texture of the size that you will output your displacement map at and then pressing AUVTiles? Or are you just pressing AUVTiles?

i choose guv tiles and just hit the button, with no assigned texture. only a simple fast shader on the model.
