View Full Version : zbrush normal map issue

08-06-2012, 12:37 AM
having an issue with a zbrush normal map

attached you will see a seam down the nose..this disappears once the normal map is disconnected..

I am not sure of the proper normal map settings for GoZ but I have tried most possible settings with the same issue

also UV check passes fine in zbrush....so no overlapping UV's as far as I can tell

manually fixed the map in PS....visible artefact at that point
must be a zbrush issue...not LW

still any insight welcome

don't forget to turn off mipmapping of the normal map image in LW.

if still buggy, so the problem comes from zbrush : smooth or lineear uv of zbrush vs smooth or linear uv in LW...

And make sure correct color space is used by normal map image.

If you're using Quick Preset it needs going to every image with normal map in Image Editor and changing.

ya i did all that...not that i dont appreciate the help:)

like i said.... the map itself had a visible artifact that i fixed in PS...
had to be a zbrush issue...it was there on export
