Vray and FumeFX Rendering issue ..

[TobiRe96]

Hey guys, whats up ? 

At the moment I´m working on a small project on which I am doing the CG effects. In one Scence there is a helicopter crash on that I´m working since today.

However the problem appeared that when I want to render the chopper breaking into pieces , causing a huge explosion done with fume, the flames and the smoke seems very dark and rather dense. it is transparent and you can barely see any smoke.

My seen Vray setup is :

Vray Sun , CIE Overcast, Intesity about 0.8, Size 30, ( and indirect illumination turned on )

Exposure control --> Vray --> from Ev parameters with the Value to about 1,1

and a Vray sky 

The problem that I think causes this issue is the Exposure control. I played with the smoke and fire opacity and the Shutter speed ( at exposure control ) however I could not fix it .. 

I attached another project but sam issue  ( one time with Vray one tim with Scanline )

Vray is version 2.4 and fume is 3.5.1 

I hope that someone can help me ?
