A big headache from Extracting to create another subtool - Any help?

ZBrush Usage Questions
#1

Hello guys,

I seem to be having a lot of trouble with extracting a mesh to make a new subtool. I’m not sure if I’ve used the correct words here, as I’m not used to all the technical speak.

What I am doing is masking a pair of legs, then extracting them in an attempt to make a tight pair of trousers. The problem I’m getting is that the edges seem to be very jagged, but when I turn the edge smoother up it still looks quite jagged and it loses some detail around the edge. I just can’t figure out what I’m doing wrong.

I’m using ZBrush 4R3

EDIT

I’ve played around even more and on close inspection it appears my ‘masking’ isn’t very smooth, and ZBrush is replicating the jagged edges of this. I could be wrong though, but I’ve included a couple of pictures to show you what happens.

Is there something wrong with my mask tool, and that’s why it’s all jagged like that? I’m following a tutorial and it uses the extraction tool on both the same subdivision I’m currently on (6) and on level 3 and none of these problems occur for him.

Try with brushes like trim dynamic / adaptive to make the edges look better and maybe extract at bigger SubD level.

I’ve edited the post above and added a couple of links for pictures.

I’ve tried going to a more higher subdivision level like you suggested but it’s still giving me the same results.

The problem is that the leg is on an angle and it looks like you are just using a Rectangle stroke for the mask, making it flat on the top. You are not following the topology of the leg. Turn on PolyFrame (Shift+F) so you can see the cage and follow the topology. Use the Lasso stroke instead of the Rectangle stroke.

I would do one of these:

  1. Go to the frame (shift F) mode somewere on low or mid subD lev and try to mask the foot along the edge loop with mask lasso tool then maybe move to higher level of subdivision and extract

  2. Extract as itis now, then mask up the region I want to edit, inver4ese mask and smooth it down and use a trim brush a lil.

Both ways should work fine.

Or if you don’t care about a polygon count you can extract as it is, then dynamesh it and then use clip brushes to cut out the bad area.
