I’m trying to sculpt a human and have made a nice hand. The polycount is quite big, so I wanted to test if it would be possible to make a retopology and transfer the details to it. As aspected, it didn’t work really well. The fingers are too close to each other, so Zbrush can’t project the details correctly. Is there a workaround for it?
If possible, try spreading the fingers apart (I recommend using masks to isolate each finger, draw a transpose line and then rotate). I understand you will have to redo your your retopo and (unfortunately) it may take some time. This isn’t the only workaround, but it’s one likely to give decent results. Goodluck!
Know that you can use the ‘ProjectionShell’ slider to control how far away in distance ZBrush scans from the target mesh to find the source mesh in order to transfer the detail. It could be that right now ZBrush is looking much further than the empty space between individual fingers to look for details and thus gets “confused”.
You can also play around with the ‘Farthest’, ‘Outer’ and ‘Inner’ buttons as they’ll further allow you to modify how ZBrush scans the area surrounding the target mesh.
Right, there’re so many options in zbrush, you overlook the one that are obviously 
It worked now really well, although, there were some wrong regions. So I stored a morph target and used the morph brush to clear the areas out and redo them. Thanks
