Vray 2.0 for Rhino Interiors issues

[alessandrasalerno]

Hello! First, let me introduce myself: I'm a young architect and I've always used Rhino 4.0 + Vray 1.5 for my very basic renderings. I've never been good at this so I never really went into Max and more complicated stuff. The issue is that our "official" renderist at the office decided to leave our office yesterday, leaving us with some renderings to finish before the deadline of a competition we've been working on for the last couple of months.

 

I have to deal with this file, now. It's Rhino 5 + Vray 2.0, and I must say I find it way more difficult than Vray 1.5. I'm really lost.

 

I have an interior scene set with Standard Materials, a Sun system and some inernal rectangular lights, (settings screenshots attached) but the result is far from being acceptable. I have absolutely no idea why this is happening. Plus, the rendering time of the image I posted is over three hours, and I'm working on a good computer.

 

And anyway, what do you think that weird rainbow reflection is? (Circled in red on the image attached).

 

Here's a link to my complete vray settings, both screenshot

If anyone could help me I would really appreciate this.

 

Thanks a lot,
