Vray Caustics Problem - Club house Pool - Help Needed

[IfthikhauAn]

Hi friends,

 

Here is a wip of my latest project.

Its a low quality with proxy hidden version.

 

And i am facing a problem here with Vray caustics.

Caustics is only visible in reflections and not in refractions(inside the pool). any solution?

i tried asking in evermotion forum as well but no response yet.

this is the only thing i am stuck with now and have to send this to client soon!

 

Using Vray sun with HDRI for lighting.

 

Attaching the images.
