Is There a Way to Use a Subtool as a Mask?

ZBrush Usage Questions
#1

Aloha Z Brushers,

I have a character I am working on. I am sculpting his belly out so his excess weight hangs over his boxer shorts a little bit. I have the boxer shorts as a separate subtool; is there any way I can use the boxer shorts as a mask so when I push his belly fat around it won’t push through the boxers, but instead be stopped by them and push up against them?

I would guess this is a feature in Z, but I am not locating it and google searches are coming back empty handed.

Any help is greatly appreciated.

Generally other subtools get ignored when sculpting. That might sound lame in this regard, but I think that might be what enables each subtool to contain the maximum number of polygons that the system can allow.

What I’d try, if the clothing doesn’t stick out too much, is to give it a black MRGB, and use Zapplink/Projection Master (or ZProject) to project it over and convert to a mask. In Zapplink/PM’s case:

1.turn on the black subtool (boxers), get a good view
2.export the document as a psd file
3.turn off the black subtool
4.use projection master then zapplink over to photoshop
5.paste the exported psd into the zapplinkfile, and then zapplink it back to zbrush
6.pick it up from projection master and then mask by intensity.

Thanks for the reply and the workaround. I’ll give it a go.
