I agree with Žuger (albeit its tone of speech could be a bit more urbane) as far as the explosions go:
Bombs and shells: a flash immediately covered by very dynamic projection of matter and smoke (smoke only for flak shell explosions!), then drifting or diffusing smoke. Note also that the delay-fused bombs are impacting the ground in a specific way (small cloud of matter and dust ring); their later explosion will be conventional.
Aircraft crashes: "Hollywood-style" explosions (A/C "explosions" are only high speed gazoline dispersion) except if bombs were carried and one or several of them decide to explode: it should be a compound of the two types mentioned.
A bit different, the explosions within fuel depots and the like, whose visible part would be a ball of flame immediately engulfed in massive fires with billowing smoke (you do not have the high speed fuel dispersion of an airplane crash for most of the concerned fuel)
In any case you never "see" across the flames or matter/dust dispersion clouds at explosion time. I think this effect is a limitation of the Il2 engine and the way the effects are implemented.
That's about as polite as I get
I don't agree that this is a limitation of the game engine, notice when you hit a A6M5 in the gas tank, that seems to be fairly well modeled. Now if that were taken to another level and some how incorporated the existing effects for like you said
it should be a compound of the two types mentioned.
a flash immediately covered by very dynamic projection of matter and smoke
it may look closer that what it is. So if there is anyone that can answer this... even a simple yes or no would do, I and JV would appreciate it
