X-ray lights render differently on different versions of vRay

[ANDREW_CHAN]

Attached is a comparison of two renders of the same scene using the same x-ray light material downloaded from your website- rendered using two versions of vray. As you can see, the material renders differently on the new vray beta.

I prefer how it renders on the current 1.05.29 build. Is there any way to get it to render the same way in the beta? Am I doing something wrong?

Thanks,
Andrew
