How to Bring your UV layout into Zbrush?

ZBrush Usage Questions
#1

I unwrapped my creature and I was wondering how do I bring in my UV into Zbrush so I can see them.

thanks in advance

#2

go to your lowest subD
tool>import>pick OBJ with UVs

done.

#3

So I do it twice? I have the obj opened already in zbrush that has the UVs. I used XSI and Roadkill to do the unwrapping

#4

if you already have your UV’s in zbrush, then what was the point of this thread? or am I missing something?

#5

I just dont see them in Zbrush. I am new to Zbrush, and will be texturing my sclupt and just wanted to know if I need to load my UVs or anything. Do I have to do anything in Zbrush or are the UVs just for when I take it back into XSI?

#6

Ahh…i see the question

If you want to check your UV layout just
tool>texture>UV check

In your texture panel you will see a small version of the texture layout. Gray = good. Red = bad.

If you import an obj from XSI with UV’s already on it…then you’re all set. If you start in Zbrush, or want to change the UV’s that is a bit different.

#7

when I did this my Model turned Red… I have already started sculpting, I unwrapped in XSI using Roadkil, my Clusters in XSI might have been messed up I might of had multiple UVs. or something…

Can I go back and fix this problem without loosing my sculpting that I have done already? any suggestions how to fix this?

Thanks

At level 1, simply import a new version of the model with updated UV’s. You won’t lose anything that’s been sculpted at earlier levels.

Did you store a morph target before dividing the model? If yes, switch to it before you import the new UV’s, then switch back from it before you return to the higher levels. If you didn’t store one, then do so before you import the new UV’s, and switch to it before you go back to the higher levels. Otherwise, the new import will be larger than the level 1 that’s been affected by subdivision smoothing, and that will affect the higher levels when you go to them.

Changing UV’s has no effect on geometry. However, it is important that you don’t do anything to change the point order of the model. If the point order changes, the model will explode when you return to the higher levels.
