Question regarding masking

ZBrush Usage Questions
#1

Hi, and thanks for reading my post.

I have a question regarding masking. Is there a way to prevent the masking brush from bleeding over an edge to another face? I will use a simply example. Lets say I have a cube and I am painting a mask on the front face. I want to mask the complete face, edge to edge. When I do this, I notice there is some mask brush strokes on the side faces. I don’t want that. I want the strokes just on the face that is facing me, not around to other faces. Is this possible?

Thank you.

It bleeds across faces because the faces share the vertex, and the masking value is stored at the vertex level (extremely similar to vertex colors / polypainting). It’s not possible for a vertex to exist in a state where it is both masked and unmasked at the same time, which is basically what you’re hoping for.

If you want to mask a single face and no others, the solution is to split/disconnect the face so that it does not share vertices with neighbouring polygons.

(sorry for my english):

Go to Brush Menu > Depth > and there, before you now activate the button -Depth Mask-, hold the Ctrl key down on your keyboard (for masking), so that the -Depth Mask- by activation is activated for masking.

Now the circle there at the left side, in that menu, has get tree new points (at the botton one, in the middle and above). Now push the bottom point of that circle into the middle of the circle so that the circle halves, so to speak).

Now you can with holding Ctrl (for masking) mask your one side of that cube, without reach an other side.

If you finished with masking, you can to check if you’ve sure only masked one side of the cube, with the:
Tool > Visibility > HidePt (Hide Unmasked Points).

And wuala… :wink: You’ve your evidence.

PS. Otherwise check here:

You could probably just use one of the Group options (ie group front) the face you want to work on.
