I had a nasty flicker when I selected a tool and moving it across the screen. Flicker was really bad when using the orbit tool. Disabled "Hardware acceleration" and hey presto!!" problem solved

I design for an Audiovisual gear company and get asked to do renders of stage designs showing the light beams.( like you get when using a haze or smoke machine) Is this possible in Vray for Sketch up.

Any help would be much appreciated
