Material editor issue

Hi,

I guess I reported this issue before, but cannot find the post, here is the screen shot of my material editor, please help.

Ps: restart 3ds max solved the problem, and it come back after few hours

Can’t say. Try using the V-Ray material swatches instead (untick 3ds Max material swatches in Render Setup> Settings> System).

Hi this issue come back randomly, picture 1 : 3ds Max material swatches tick picture2: 3ds Max material swatches un-tick
