This is a last-minute patch to address #113898. There are two remaining known limitations, which are accepted for now: - Drivers/keyframes don't transfer to the extra nodes in automatic conversion setups (such as for Subsurface Color) - Drivers/keyframes on Sheen Tint/Specular Tint only apply to the R channel, since they were changed to color inputs in 4.0 Pull Request: https://projects.blender.org/blender/blender/pulls/114300
