Problem Generating Subtools Normal Map?

ZBrush Usage Questions
#1

I just recently picked up a copy of ZBrush after seeing many wonderful things you are able to achieve with this program. So far, I am loving ZBrush.

However, I ran into a problem when I tried to create normal maps for SubTools. I imported a character I have from Maya to sculpt details. The character was then separated into SubTools using UV offset (I followed the video tutorial Normal Maps for Maya in http://www.pixologic.com/zclassroom/homeroom/) After I am done sculpting, I used the Normal Map subpalette to generate normal map for each subtool, but I was not able to create a single normal map like the tutorial, instead I got many individual maps.

So is there any way to combined normal maps in ZBrush?

that tutorial is from 3.1 I believe.

In 3.5 you can do some 2d work to achieve what you want. You’ll need to import each texture (if not still in your texture panel). then crop and fill the canvas with one texture. create a new layer. fill with the new texture. erase away the extra.

basically the same thing you’ll do in photoshop, but you can do it in Zbrush.

I was wondering how to do the same thing and I accidently figured out how to make them all one normal map without doing anything extra. I took each subtool into Zmapper and created a normal map for it, but instead of exporting the texture after each one I left it there as I went to create the next normal map. For whatever reason whenever I’d move back to the main screen it would add the normal map for the next subtool directly to the texture I left. After I normal mapped all the subtools I just exported the entire texture with all of them including :slight_smile:
