Project all on clothed model

ZBrush Usage Questions
#1

I have a question about modelling clothes in Zbrush. I created a character (comic) that should wear trousers and a shirt. I modeled the character first and then added shirt and trousers by using masks and Extract to the highpoly version.

Then I polypainted the whole model and merged it to one subtool.

I used Zremesher now to get the lowpoly version and then I used Project All to project the highres to the lowres, continouesly deviding the lowres.

If I do this process with the clothes, I get holes on some parts of the clothes.

If I leave the clothes away then the projection is just fine.

Could someone give me a hint were my workflow is bad and what I could do better to get a clean mesh with clothes on which I can project to?

Kind regards
Jay

Are they actual holes, or just areas where the projection didn’t happen? Project All can’t unweld points, which means it can’t create holes unless those holes were actually there from the start in the form of points that aren’t welded. In all other cases, what would be happening is that part of the mesh moves and part doesn’t.

This latter situation should be able to be handled using the modifiers next to the Project All button. For example, you can adjust the distance that ZBrush will look at to find something to project onto.
