Sculpting single side only (not x symmetry type question)

ZBrush Usage Questions
#1

Hi peeps,

I am pretty new to the wonder that is ZBrush but am getting on woderfully (nearly ready to post something for C & C :confused:).

My question is regarding sculpting, polypainting or masking coming through your geometry onto the adjacent face and how to stop this happening.

Basically I am working on a shield that I created the base mesh in LW then into Zbrush, now my problem is that the details I sculpt on the front of the shield are also being applied to the reverse of the shield.

Not the back of the poly but the opposing poly facing the opposite way.

I noticed this when you extrude a new subtool via a mask in ZBrush too, the new tool that you have created although solid, when you sclpt on the front face applies to the inside which is fine on clothing etc as it is not visible but some things like the shield for instance need the reverse to stay untouched.

Please help
Thanks in advance
Dean :wink:

Also too, in addition to the back face mask setting. Sometimes you run into areas where it’s too thin and then back face mask doesn’t work good. You can reduce your draw size on your cursor, which can help, but sometimes when areas are way to thin, it becomes impossible to effect just one side.

In those situations, what you can do is scale your object using the scale command in the transform palette and scale your object in the direction that makes it thicker.

Then you’d hide one half using control shift marquee select.

From there you’d go to Polygroups under the tools palette and click on the button that says Group Visible.

Then you’d show everything using control shift and clicking anywhere in the view port but not clicking on your model.

Then you’d scale it back to the original size.

So now even though your model is super thin, you have two poly groups! =D

So then you just control shift click on the group you want to work on and everything else becomes hidden and you can sculpt away. :slight_smile:

The groups method is interesting.

Can you bring groups from other packages into ZBrush, so if I created a mesh in Maya or LW could I apply groups there and import to ZBrush?

I don’t use those so I can’t say, but I would tend to say no.

You could do it with UVs and textures tho and then after importing implement the tools, polygroups, Uv Groups command.
