Smoke and flames disappear and reappear??

[AlfredIl2AlfreS]

Hello everybody

 

I have detected a strange behavior using Tank Crew... when a vehicle is destroyed, the flames and smoke left over from the explosion are ONLY VISIBLE at very short distance or with high zoom levels... because of the latter, through the tank's own scope the effects are visible... but in external views the problem becomes very evident...

Is it possible to solve this? Graphical Configuration problem perhaps?

Many thanks in advance
