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 "Object Properties" > "Visibility" > then checked the box "Shadow Catcher". I also checked the box labeled "transparent" under "film" in the "Render Properties" 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
