VrayEnviromentFog falloff + emissions

I have problems with enviroment fog connected to a spheregizmo.
If I add some fog emissions and add a falloff something breaks and it turns out completely white, overexposed.
Using vray 3.60.04, tried both max 2017 and max 2018.

Am I doing something wrong? is this a known issue?

There is something suspicious about that indeed, I am looking into it right now.

It looks like very similar issue that already got into our bug-tracking system where fog emission texture produce overexposed result.
I’ll add additional note about that just in case and will keep you posted for updates.
