ZRemesher to preserve poly groups?

ZBrush Usage Questions

Hi,

Is there a way to get Zremesher or Dynamesh to preserve polygroups?

Thanks

ZRemesher has a FreezeGroups option.

The Freeze Groups mode retopologizes each Poly*Group independently, keeping their borders frozen and then welding the edge vertices together along each PolyGroup border.This results in a model with the same PolyGroups, but with a different topology flow within each group.

Because it preserves the existing vertices, it may make it harder to get a result with a significantly lower polygon count. Instead you could use Stroke:Frame Mesh to create curves around each polygroup, and use them to drive zremesher. You may have to rebuild the groups afterwards though, but the edgeflow should be there for it.
