  Ambient Occlusion Shadow Multipass?

  Posted by Jason Shevchuk on November 18, 2010 at 2:58 am

  I’ve a scene lit with a sky object. Creating shadows on the floor with GI and Ambient Occlusion.
  No lights.

  I’m doing a multi pass of AO and GI as well as my Object buffer…and the shadows aren’t coming through at all.

  what am I doing wrong?

  thanks

  Yes. I’ve tried Shadow…even Depth.
  It’s not recognized as a shadow

  the multipass Ambient Occlusion channel will have the AO but I don’t think you can pick up the “shadowing” of GI only it’s additive lighting.

  Thanks.
  I was able to do it by adding an External Compositing Tag to my floor.
  Worked like a charm

  Hi,

  Is the only thing you added an external compositing tag? I have tried this to and can’t get it to work even with that tag. Perhaps there is some more setting I haven’t considered?

  Could you repeat in just the few steps I need to do to get GI shadows in multipass?

  best regards
