Vray 5 refractions way to dark

[o-v]

Hello there. I have on big and pretty urgent issue at the moment. My refractions are extremely dark and I can't figure out why. And oh boy I tried...
Any hint or help is very appreciated.
Thx a heap!

up refraction max depth in your VRayMtl.

It is at 20 already. Scene is attached as well btw.

It is the falloff map in the 'Backdrop' shader...switch off, no problem
Although if just reflection is used then the problem persists...weird....must be a solution...

And there is...just up the max reflection in that shader

sure but saving to 2021 in 2021 is just way too optimistic.
