Zbrush - Is there a way to create a polygroup while using an alpha for height detail?

Dez

Hi, First time posting here.

I am using the DragRect mode with an alpha to create rocks on a dirt mound and I was wondering if I could create a polygroup at the same time. The idea is to later use the polygroups as ID masks.

Is this possible and if so how would I go about it?

One way to do it is to enable RGB while sculpting and change the colour for different rocks/groups of rocks. Then you can use the Polygroups from Polypaint feature.

Another way is using inserts(with a negative imbed) and dynamesh will preserve the groups.

Hopefully there will be a auto-masking feature for VDM brushes - just like IMM - in the future.
