Conforming Mask Question :

Is it possible to have a mask ‘stick’ to the geometry when painting it onto an object?

I want to work on one finger. I was hoping to do this by masking the finger and then inverting the mask so that I can work on just one finger without disturbing the others. The problem is that painting a mask onto the finger without it spilling over onto the other fingers, is a real pain in the arse.

Is there a way to make the mask sort of stick to the geometry rather than just paint over everything?

The mask lasso / select lasso brushes would be an excellent choice for areas like the fingers.
Transpose + Ctrl will also do a decent job at isolating them.

Otherwise, you could hold ctrl and expand your Brush: Automasking options. Topological will give you a good start, but you might have to play with the values to completely prevent spilling.

Thanks, Topological is exactly what I wanted, it seems to be broken in mask mode though.

It works for sculpting without a mask, but any Topological options I set while in Mask mode (while I hold down CTRL) don’t appear to effect the mask at all, the mask continues to behave as if it has no Toplogical options set whatsoever.

:idea: Hide a bunch of the mesh you don’t need there and frame mesh, repeat as needed to get to the parts you want. Have fun.
Automasking doesn’t show ;).

Thanks Doug, but that’s not an option on something like a fist if you were wanting to unpose it after posing it, it would be too much messing around.

Can you please confirm that Topological is not working in Mask mode?
I just want to be sure before I report it as a bug.

Also, is there a list of bugs so that I can check whether it’s already been reported or not?

Question, are you using ZBrush 4R6 P2?

Yup, ZBrush 4R6 P2 here.

Your workflow differs from mine. Masking isn’t needed for my method of posing. After creating the T pose armature, I make an adaptive skin to refine into my model. Groups are created which make this a bit easier. I pose with the ZSphere armature after modeling by using the Rigging panel. As I stated you can hide parts that are of no concern and focus on the parts that matter. HTH.

Cheers Doug, I’ve never tried that before, haven’t really got into rigging yet, still getting used to the sculpting side of things!

I’ll look into ZSphere rigging, but I’d still love to know whether you or others have the same problem with the Topological Mask, and if so, is there a link where I can report it?

If you were to post an image with poly frames enabled we may be able to advise you better. Unless you can upload the tool for us to try and tackle ;). Images really help us out. About wordy enough here already. Searchable forums as well as searchable docs linked to below my post. HTH

Haven’t got the sculpt now, it’s been transformed beyond all recognition since yesterday!

Anyway, I came across a cool feature in the online documentation last night:

  • Go into Move, Scale, or Rotate Mode
  • Hold down CTRL
  • Aim the yellow dot at the tip of the finger, hold down the mouse button and drag-along up the finger.

You get an automatic Topological mask running up the finger without effecting the others, awesome. I still don’t know whether the brushable Topological mask is broken though, or where to report it if it is. Have to say it looks broken to me because it works in sculpting and even smoothing mode, but mask mode fails to have any effect.

I don’t need it is as much now due to the feature above, but it still needs reporting and fixing if it’s broken.
