Thank you very much for the replay.
Unfortunately I tried all you said, but no results. I also changed the shader in the Appearance category with nothing happened.
I happened to notice that there is a thing called “Shade Model4/5” we can choose from, which may have sth. to do with my situation? :rolleyes:
The problem is that why do I only have Shade Model 4??
I am using a quite new iMac with “NVIDIA GeForce GTX 780M” which should support Shade Model 5…Any ideas?
