I have a problem with my Object that I want to apply a linear gradient onto to simulate a 3D effect (glow on top of a button).
It looks fine in the editor but when exported the gradient area is going to transparency instead to a lighter version of the base color.
When trying to edit it I can't see any way to define the "destination color".
I'd like to make the destination color (marked with red arrow in screenshot) a lighter red instead of transparent. I can't figure out how to edit that.
