I dont know why but suddentlly I see squares where snoke should be.I havent touched or deleted a thing.what could it be ?

Just wondering if that is some sort of problem with an exhaust texture or even the contrail texture not showing up? I'm just saying because it appears centered around the engines and this thing pops up once in a blue moon with my FS9 when my video card is a little late displaying the contrails at high altitude. But then a second or two later, the contrails display properly for me.

Either something's not loading correctly, or your effects textures are somewhat broken.Is it your altitude contrails or smoke effects?
