Material cancel subsurface BUG

Just find a small bug when cancelling change material which affect subsurface.
Here is two cubes,one with green material on a subface.

Modify the color of GREEN to yellow affect the subface.

Cancel this action let the subface yellow.

Simple to reproduce



What Rhino version do you have? I believe this is fixed in the latest Rhino 6 Service Release.


6.12.19023 i’ll give a try to the new one

No… i’ve just update to Rhino 6 SR12 2019-1-29 and it stillo working… give a try.

If you modify the color definition everything update normally, but if you cancel it with the image the subsurface won’t update.

Thank you @BEMAD - I can reproduce the bug when using Undo.

I made a YouTrack item:

RH-50584 is fixed in the latest Rhino 7 Service Release Candidate
