Title: Ambient Occlusion Behind Transparent Materials
Post by: wiinter on 2017-01-14, 21:01:39

I've been able to get ambient occlusion to work with Corona A6 (Cinema 4D) using the multi-pass feature.  But it doesn't seem to evaluate anything behind glass or transparent objects.  No options for this, that I can see. Idears?

Sorry, but I think it affects everything globally. Same for 3ds Max version.
I can't even see a good solution to this - some parts of the image would have to be semi-transparent? What about reflections, and other features...?

This is typical of most render engines.

But..  If you tick the glass not to be visible in masks then the AO pass will ignore the glass and render as expected.  You may run into a problem with refraction of glass as I don't think the passes currently take this into account but I could be wrong.
