I think it's very very not simple problem ...
Because it is connected with crew skinmorphing and may be with adjustment
of bump mapping ...




You can simply turn off alpha in VolumetricFogPS.fx:
Befor:
return float4( fogColor/*+brightness*/, alpha*0.5);
After:
return float4( fogColor/*+brightness*/, alpha*0);
...
But this action will have the same effect as well as turn off Volumetric Fog ...
