A question about the grenadelauncher zasleh fx

[At.St_Walker]

hello
i've a ww2 flamethrower under costruction using Mav's scripts .
The flamethrower work fine (it's a grenadelauncher) ingame but i wish to add a pilot-flame on it using the standard BIS muzzle flash (aka "zasleh").

My problem is.. i can't see ingame the transparent smoke-textures on it that occur the split-second the weapon is fired but a damned puff of smoke <_< perhaps because the mm1 addon was added with Resistance :hm: ..

How i can show a zasleh fx when the weapon is fired ?

tnx,
At (sorry for bad english)

PS: with a standard smoke cloud class placing it OUTSIDE the class cfgVehicles section i've removed the puff of smoke but  i can't still see the zasleh
