It doesn’t seem to work with mask rectangle.

Is that a plane? I don’t believe that’s going to work. Maybe a different approach with the ZModeler brush will work for you.

#6

the plane like any mesh…the same thing…the backface fail?! how can use it?

If I try to mask an sphere or cube with backfacemask active using MaskRect it will mask also the back faces of the opposite place of the object, no matter how far away they are. Not sure if this is the expected behavior and certainly it is not intuitive.

Also if you use the normal Maskpen it will mask the back faces no matter if the backfacemask is on or off.

The masking settings I’m talking about are in brush - automasking. Do we have any other backface menu that I’m missing?

Sorry, perhaps it is my fault, but I can not see in your link or the link inside of the link anything that solves it or it is related to backfacemasking. It seems the only way to avoid it is hiding the faces.

What version of ZBrush including the patch number, OS? I’m afraid I can’t help you much more w/o that(we all want to know) Sorry if there was no answer there that you wanted to read or hear.

This seems to be the expected behavior of Zbrush unless I’m missing something. Tested with the last version windows 4.7r3 64 and 32 bits and also with the version 4.6 also windows.

Polygroups> Group Front>> Hide the back polygroup. Cheers

Well, that is an excellent workaround. Also I was trying today to select some tricky front faces and this would have done it a lot easier.
