Zbrush Masking Not Working On Certain Subtool

supermoby

Hey folks,

Just like the title says, I press Ctrl for masking and instead of masking the area I get this (see attached).

Any ideas why this might be happening - it's only on a certain subtool, the rest work okay.

Thank you

Looks like you're using the special bumpviewer material
