Hdri Reflection/Refraction

[carlofollo]

Hi, sorry but I didn't find an answer to my problem.

 

I'm making my renders with vray on sketchup, using an HDRI from Peter Gruthie's pack.

The problem is that I have some glass that reflects and refracts the HDRI, which is what I wanted, but it's also doing the same for the big black background of the hdri. I havent constructed a background for the scene, cause I simply find myself more comfortable doing it after in Photoshop and it wouldn't be a problem if I didn't see it on the glass and through it.

 

Do you know how to deal with this?

 

Thanks in advance
