Can't control color ramp node color values with drivers
Closed, ResolvedPublic

Description

System Information
Windows 10

Blender Version
Broken: All versions. "Works" slightly better with new depsgraph.

Short description of error
Attempting to control the color value of a color ramp color block with a driver either A.) fails completely with old depsgraph or B.) fails to update properly with new depsgraph.

Exact steps for others to reproduce the error
Attached blend file already has drivers set up in a way that would be expected to work. RGB nodes should drive the color values of the color ramp node. In old depsgraph, nothing happens. In new depsgraph, values only update when interacting with the color ramp node.
