Prepass issues with High and Low preset settings!

[Farhan]

I am trying to render a walkthrough of an interior using saved IRR Map. When I try to render the Irr Map, there is only prepass for both High and Low preset settings. I think it should be more for High preset settings, right? I have 21 vray lights in the scene, for different rooms of the villa. Does anybody know why Vray is behaving this way?...Thanks in advance!

If you have DR checked, there will be only one prepass.

Yes, or make sure you have multi-pass radio button checked.
