Anyone have a “simple” tutorial they could point me to that explains how to remove the background of a zbrush render pass using the zbrush render pass mask? I did it a long time ago but can’t figure out how lol 
With the mask and color pass rendered, I load them both up in photoshop.
- Select the entire mask-pass document and copy it
- Switch to the color-pass, and with it’s layer selected add a layer mask.
- Select it’s layer mask, switch to the channels tab, make the layer channel visible/select it, and then paste the mask-pass into it
Thank you man
