HI Cheshire!, Thanks for your compliments . I didn't know about this whole thing here, I would never have checked my messaged here. So thanks!, It's actually quite cool.
In zbrush you can paint a mask on your object, lets say for example a circle with a hole in the middle. Then under the subtools menu, hit 'extract', and it will create a new mesh from the masked portion. Then, you can model on this mesh, and when done, hit 'project all' , to bake it back into the original model.
This can be used to model ripped clothing, armour, buttons, and many other things.
Hope this is useful, feel free to ask anything else
I didn't know there was such an option to create torn fabric in Zbrush.. I mean I'd know how to import a low poly mesh with "holes" in it and then detail it in Zbrush, but how do you create "holes" (torn fabric for instance) in Zbrush?
Did you import a low poly mesh?
