Rendering Clear Glass with Shadow Catcher and Transparent Background (Glass looks white instead of clear) This is the coffee cup that I made and it is rendered with the cycles engine on top of a white plane:

This is the coffee cup that I made and it is rendered with the cycles engine on top of a white plane acting as a shadow catcher. AKA for the plane I selected &quot;Object Properties&quot; &gt; &quot;Visibility&quot; &gt; then checked the box &quot;Shadow Catcher&quot;. I also checked the box labeled &quot;transparent&quot; under &quot;film&quot; in the &quot;Render Properties&quot; tab:

I am trying to composite this cup into a video (using davinci resolve) so I need the background to be transparent but the cup just ends up looking white instead of clear. Is there a way to make the cup have a shadow while still being mostly transparent?
Btw, I'm using Blender 2.83.5
Under &quot;Film&quot; also check &quot;Transparent Glass&quot;
You must use a Glass Shader on your glass, adding a Gloss Shader mixing a with Fresnel works, too.

It is possible to save the alpha channel separately.
