ZBrush ZBrush Masking and Selection 1 — Questions and Answers
Question 1: How do you paint a mask on a mesh in ZBrush?
- Hold Shift and paint
- Hold Ctrl and paint (Correct answer)
- Hold Alt and paint
- Press M then paint
Correct answer: Hold Ctrl and paint
Holding Ctrl while painting applies a mask to the surface, protecting those areas from being sculpted.
Question 2: What happens when you Ctrl+click on empty canvas space with no brush active in ZBrush?
- Clears all masks on the active subtool (Correct answer)
- Creates a new subtool
- Deletes the current selection
- Opens the mask options menu
Correct answer: Clears all masks on the active subtool
Ctrl+clicking on empty canvas clears (removes) any existing mask from the active subtool.
Question 3: What does 'Ctrl+click on the mesh surface' do in ZBrush when masking?
- Inverts the current mask (Correct answer)
- Adds to the mask
- Blurs the mask
- Clears the mask at that point
Correct answer: Inverts the current mask
Ctrl+clicking directly on the masked mesh inverts the mask, switching protected and unprotected regions.
Question 4: What is 'Mask by Cavity' used for in ZBrush?
- Automatically masks recessed/concave areas of the mesh (Correct answer)
- Masks hollow internal geometry
- Creates holes in the mesh where masks are placed
- Selects only open-boundary edges
Correct answer: Automatically masks recessed/concave areas of the mesh
Mask by Cavity automatically generates a mask based on the concave areas of the mesh, useful for targeting creases with paint or sculpting.
Question 5: What does blurring a mask in ZBrush achieve?
- Creates a soft, gradual transition between masked and unmasked areas (Correct answer)
- Reduces polygon density in masked areas
- Applies a Gaussian blur to textures
- Feathers the mesh boundary
Correct answer: Creates a soft, gradual transition between masked and unmasked areas
Blurring a mask softens its edges, producing smooth gradient transitions that lead to less abrupt sculpting boundaries.
Question 6: What is 'Mask by Polygroups' used for in ZBrush?
- Automatically masks all polygons that belong to specific polygroup colors (Correct answer)
- Converts masks into polygroups
- Groups all masked polygons into one polygroup
- Removes masks from ungrouped polygons
Correct answer: Automatically masks all polygons that belong to specific polygroup colors
Mask by Polygroups automatically creates a mask based on polygroup boundaries, quickly isolating specific regions.
