I have a quick question. I just got the Vray 3 interiors tutorial and I'm working my way through the series. I am using Maya 2015 Ext 1 SP5 with VRay 3. I notice that both in IPR mode and in the viewport window I do not get any GI rendering. My setup, I believe, is exactly what you have in the tutorial. If I click for a render, the GI comes through but both Vray RT and the Vray Viewport do not render GI. Is there some special check box I need to set for this to work?
