Title: render elements: Glass mask
Post by: johan belmans on 2016-06-03, 19:36:47

Hi there,

it could be that the following is possible, but I did not find a solution up till now.

We have moddeled some high detailed windows with glass planes included (one mesh).
We do not want to detach the glass planes from the original mesh.
If the glass material has the "visible in masks" option enabled, The glass will show up in a mask (render element CMasking_Mask). Which is obvious.
But whenever a tree is behind the glass, the mask (again render element CMasking_Mask) of the tree will only show the part which is not behind the glass.

Whenever the option "visible in masks" is switched off, the whole tree will be visible in the mask. Which is obvious. But I cannot create a mask for the glass.

So I would like to have a mask of the glass and a mask of the tree behind the glass without rendering twice.

Anyone an idea?
