RTT Reflection map

I’m completely stumped.
I have some hirez stones with a vrayblend material, mixing between some procedural granite and some dust through a vray dirt map.
I originally wanted to proxy this out and use it in Railclone, but Railclone goes completely nuts when adding the proxy as a segment, even in box mode.
So I need to bake this down to a low rez version.
How can I get Vray to RTT-render out the reflection map I have set up. There is no reflection option in the RTT dialogue, only vray reflectionglossiness.

Is there no way of doing this?

You need the reflection color? We added support for that in the recent nightly builds, I guess I can get you that if you need it.

Best regards,

If it gives me what I’m piping into the reflection slot on the vraymaterial, then yes. Why has this not been possible until now?
