ZBrush Hard Surface Sculpting 2

Question 1

In ZBrush hard-surface workflows, what is the purpose of Polygroups when used with ZRemesher?

Accepted Answer

They guide ZRemesher to keep edge loops aligned to polygroup boundaries, preserving hard edges

Answer

When 'Use Polygroups' is enabled in ZRemesher, it treats polygroup borders as hard creases, ensuring the remeshed topology follows the panel layout of the hard-surface design.

Question 2

What does the 'Make Boolean Mesh' button do in ZBrush?

Accepted Answer

It converts a Live Boolean preview into actual polygonal geometry

Answer

Make Boolean Mesh processes all Live Boolean SubTools and outputs a final, committed triangulated mesh representing the boolean result, placed as a new ZTool in the Tool palette.

Question 3

What does the QMesh action in ZModeler allow you to do?

Accepted Answer

Extrude, bridge, or push through geometry from a face with a single drag, including punching holes through meshes

Answer

QMesh (Quick Mesh) lets you click-drag a polygon to extrude it outward, push it inward (subtracting through the mesh), or bridge to another polygon — all in one gesture — making it extremely fast for hard-surface modeling.

Question 4

What are Slice brushes used for in ZBrush hard-surface work?

Accepted Answer

They cut the mesh along a drawn curve, inserting new edge loops and creating separate polygroups on each side

Answer

Slice brushes (SliceCurve, SliceRect, etc.) insert a line of new edges along the brush stroke, assigning different polygroups to each side — ideal for defining panel splits on hard-surface models.

Question 5

What is the recommended method for getting clean, hard-edge topology on a ZBrush hard-surface sculpt for game export?

Accepted Answer

Retopologize using ZRemesher with polygroups and creases, then bake detail to a normal map

Answer

The standard pipeline is to sculpt at high resolution, define panels with polygroups, use ZRemesher for clean low-poly topology, then bake high-poly surface detail to a normal map.
