Weird rendering results

[wassupdoc]

I'm trying to get a decent rendering setup, but every time I try to render a simple glass, I keep getting these unsightly reflections/refractions, any help/tips/solutions would be greatly appreciated.

I am using Sketchup 8 Pro with V-Ray for sketchup.

Thanks

I use 3DSMax wuth V-ray also, are you sure it is not set up problems?

I'm looking it better now, it looks very odd really

I have used a blank setup, tried and tried again, it just happens on curved surfaces, I've tried smoothing edges and coplanar edges but nothing works
