Hi, all zbrush masters 
I am finding a render passes tuto for zbrush.
thanx
I’m not familiar with any actual tutorials on this subject. Many people have shared information about their techniques, which you can find by using the Advanced Search feature here at ZBC. But no full-fledged tutorials that I know of.
There’s a short section on compositing various Zbrush renders into a final image in Scott Spencer’s Zbrush Character Creation book. It’s a fairly simple technique using Photoshop.
