issues with Vray 2.0 in Rhino 5 (GI washout)

[dh]

Hi everyone.

 

First of all apologies if I have posted this in the wrong forum but I am having some issues with my render washing out when using GI (with sunlight on) but the materials having colour.

 

Then if I switch GI off my terrain I have modelled has very nice shadows but the materials are monochrome.

 

What I am modelling is a simple slopped terrain with some simple stairs in them (stairs have the material added)

 

Further, I have also attempted with adding bump and diffuse maps to materials which preview in the materials editor of vray but when I add it to a selection or layer the diffuse and displacement dont appear no matter how high numbers I am using.

 

I would class myself as a beginner and have started a new job which I have started using rhino and V ray again after a 4 year absence.

 

Any help would be greatly appreciated. and I apologise if this is a question with an obvious answer haha but I have searched far and wide and cant work it out

 

Thanks
