black dot lines on normal map

onionhead_o · Oct 2008

every normal bake i do thats part of the this mesh becomes screwed up. i tried different settings like global supersampler with or without it. I tried redoing the projection. I tried baking it in xnormals, which looks even more retarded. but if i rebuilt a mesh that is the same and bake the highpoly it is fine. My guess is that there is some bug in the original mesh.

whole mesh

my question is there anyway of fixing it or do i have to redo the whole mesh and unwrap again?

thanks. i just have to apply a different material and change the uv channel from where?

i have tried the scaling method and it didnt change anything. ive also tried the different material, which also failed. So now im stuck.

I had this problem a while back. I just retouched it out in PS.

Have you tried creating a box in the top view port, apllying a edit poly modifier and attaching your problem mesh to the box. Then delete the box in element subobject mode? you might have your geometery fliped and cant tell.

UNCHECK FILTER MAPS!

Squirmy: thanks you saved me. attaching to a new box seems to work the best.

if you reset x-forms and collapse down it does pretty much the same thing as the box trick (although a character artist was doing this to some hair last week and every time he reset x-forms the hair moved a bit...very weird $:\$ Box trick fixed it though)
