[C4D] General Discussion / Alpha channel behind glass
« on: 2015-09-24, 18:09:59 »
Hi to all, I'm newby with Corona, and I need some help in order to obtain an aplha channel that works behind the glass.
Anyone could suggest me how to resolve?
I have an interior scene with a glass window, outside the window I have placed a sphere object mapped with an HDR material.
My need is to extract the alpha channel in order to replace in post production the background.
I've tried all the way but I have always a full white where I have glass panels.
Thanks.
Fabio
