How to transfer high resolution details to a resurfaced mesh
While at your model’s highest resolution level, import the low resolution version of your resurfaced model. ZBrush will ask if you’d like to transfer details. Click “Yes”. The imported mesh will automatically subdivide and the high-res details will be transferred. At this stage you have the capability to refine the projection – an important capability that wasn’t possible with ZMapper – or even continue sculpting the mesh. When satisfied, proceed with the usual process of creating displacement, normal and color maps.
I want to try this but I cant figure out how.
