This may be me just being a Blender noobie, but when I try to render a Cryptomatte pass I only get one or two colors, usually green or white, with full alpha transparency for some reason (I had to check in the Image Editor to show RGB only so I could at least see what the pass rendered). The other passes seem to render OK, though.

Is there a setting I need to check or is it a bug? I'm using Blender 2.81a. Thanks in advance. enter image description here

  • $\begingroup$ How are you viewing the image on the left side? The correct way of picking the objects would be in the compositor with a view node: image. Otherwise for storing the Cryptomatte you'd save them in a multi-layer OpenEXR. $\endgroup$ – Robert Gützkow Dec 17 '19 at 9:31
  • $\begingroup$ @RobertGützkow Thanks, indeed it worked when I used it in the Compositor, but I couldn't get them to work when exporting an OpenEXR, the colors are all different when I open it in Affinity Photo. What I did was pluging the Render Layers node outputs to the File Output node, but I'm sure there's something I'm missing. $\endgroup$ – Igor Harmendani Dec 18 '19 at 2:08
  • $\begingroup$ Cryptomatte doesn't simply store color, how it works and what is stored in the multi-layer OpenEXR is explained in this answer. $\endgroup$ – Robert Gützkow Dec 18 '19 at 7:41
  • $\begingroup$ I'll read that, thank you $\endgroup$ – Igor Harmendani Dec 19 '19 at 12:03
