stack traceback error on fw:Render() command?!?!

[Soamp]

Hi,

We have an FPS player and I create an emitter (fire particles) in front of the weapon when player is shooting.

sometimes we get this weird error :

 

stack traceback:

[C]: in function 'Render'

[string "AliFPS.lua"]:63: in main chunk

 

where line 63 of alifps.lua is : fw.Render()

 

when I comment the lines that create the emitter, everything is fine and we never get this error again! did anyone face this problem before?

 

this is how I create the emitter :

 

SetWorld(fw.transparency.world)
object.shootemitter=CreateEmitter(5,100,Vec3(0,0,0),1)
object.shootemitter:SetVelocity(Vec3(0,0,0))
object.shootemitter:SetRadius(0.01,0.05)
object.shootemitter:SetWaver(10)
object.shootemitter:Paint(LoadMaterial("abstract::fire.mat"))
object.shootemitter:SetPosition(object.shootpos,1)
object.shootemitter:SetRotationSpeed(1)
SetWorld(fw.main.world)

any thoughts?
