Title: Corona C4D Material masks
Post by: rubyrieke on 2019-08-16, 23:14:58

I can't seem to get Corona to render out material masks.  I have object with selection set and various materials but can't seem to get this to work.  I have set a material ID and have a mask in multipass that has the right material ID

I am thinking it has to do with the material i am using that was brought into Cinema from Sketch Up and converted.  When I do a test on a simple cube it works fine.

Hey there!

Try using ID masks (Multipass -> ID) and set those to "Material". Still not showing up?

I tried that but it just renders as 1 material even thought the object has 2 different materials and corresponding selection sets.  I have also tried with an Mask pass with material ID which should work.  It looks like the problem happens when I have Corona convert materials from Sketchup.  Even if the material whose mask I want is a Corona material it will not render the mask. If I delete the converted materials and use 2 corona materials it renders the mask fine.
