Hi guys!!!
Ive been working on a male head for quite some time now and i finished the model… but now comes the problem. Im TRYING to use ZBrush to make a normal map to apply to the head (im exporting from max 09(finished UVW))but i always get some kind of error. Recently i got zmapper but when i make a normal map i get only fragments. PLEASE HELP!!!
low poly model 
Turbosmooth model
Normal map export! WTF!?!??! 
Does that texture map reflect how you unwrapped the model? Did you use GUV tiles? Or did you unwrap it in max?
It looks like you’re in Object Space when you should be in Tangent Space. Also you’re going to want to UV unwrap it a bit better. It currently looks a bit computer generated which isn’t going to make it easy to texture.
That’s what GUVTiles mapping looks like. It doesn’t make much sense to the eye, but the computer has no trouble understanding it.
Ok here are the results with tangent:
ZMapper
Basic normal map creation
As you can see still not working :td:
Oh and heres the zbrush sculpt (WIP) stilll need to finish some details
And the unwrap
Make sure to tell me what i need to add to this guy!!
ok heres the procedure:
-Make a low poly head
-unwrap UVW
-export to zbrush
-skulpt to hight detail
-export normal map(THIS IS WHERE IM STUCK)
-place on low poly char
THE END
i really have no idea what im doing wrong so please help!
Why does my map look like a crapy mosaic??
I want to export the normal map so i can use it in 3dsmax 09 on a low poly char… you know the procedure. the point is i want it to be in the shape of my UVW unwrap:
and not a mosaic xD
so please help me!
At some point you changed the mapping to GUVTiles. ZBrush didn’t do this automatically. You had to manually press the GUVTiles button.
To get your original mapping back, go to level 1 of your mesh and store a morph target. Now press Tool>Import and load your original mesh again – the version that has the mapping you want.
THANKS! I FINALY GOT IT TO WORK!
so heres the story…
i was using zbrush 3 and normal maps didnt work until i pressed guv tiling so i tought it was the right way… but now thx to you i finaly did it with zbrush 2!!
THANKS!
It works just fine in ZBrush 3.
It sounds to me like at some point along your process you pressed Tool>Texture>Disable UV. This erased the UV mapping. To get the mapping back you would have needed to go to level 1, Enable UV’s again, then store a morph target and import your original model again. This restores the UV’s to what they were before you deleted them by pressing the Disable UV button.
