Square pattern and stair-steping issue in Simulation

[turner_studios]

Thank you Kresimir for your response. I'm used Vray 2.45, I haven't tried it with Vray 3.0 Beta but I will do that to see if it happens there too. Also I'm not using GI, that's just when I add a Vray Dome Light or if I have a Vray Rect Light with the Directional setting to anything higher than 0, then it happens.

It sounds like you said that it's a Vray issue but wanted to clarify so if you though it was happening only with GI, you know that there are other things causing it as well.

Thanks,
Mario.
