Third person custom muzzle flash problem

[JakusPL]

I'm trying to finish my Handheld Airboat Gun but I can't solve my problem. Muzzle flash works well in first person but in third person there's still default AR2 muzzle instead of AirboatMuzzleFlash (even if there is return true!!!!).

My code:

function SWEP:FireAnimationEvent(pos, ang, event, options)
    if ( event == 21 ) then
	    
			local muzzle = EffectData();
                muzzle:SetOrigin( self.Owner:GetPos() )
		muzzle:SetEntity( self.Owner:GetViewModel() )
		muzzle:SetAngles( self.Owner:EyeAngles() )
		muzzle:SetAttachment( 1 )
		muzzle:SetScale(2)
		
		util.Effect( "AirboatMuzzleFlash", muzzle );
		return true;
		
	end
	
	if ( event == 5001) then
	local tpmuzzle = EffectData();
        tpmuzzle:SetOrigin( self.Owner:GetPos() )
		tpmuzzle:SetEntity( self.Weapon )
		tpmuzzle:SetAngles( self.Owner:EyeAngles() )
		tpmuzzle:SetAttachment( 1 )
		
		util.Effect( "AirboatMuzzleFlash", tpmuzzle );
	
	
		return true; // Function returning true, so there shouldn't be a muzzleflash, but it is!
	end
	
	
end

5001 is usually the first person muzzle flash, and I think AR2 and Airboat muzzle flashes are pretty much the same or very similar, if not the same.

No. But do not judge is it similiar or not. I need a help with coding. OK?

Ok, here's what appears to be working for me:

		local data = EffectData()
		data:SetFlags( 0 )
		if ( !self.Owner:IsPlayer() || self.Owner:ShouldDrawLocalPlayer() ) then
			data:SetEntity( self )
		else
			data:SetEntity( self.Owner:GetViewModel() )
		end
		data:SetAttachment( 1 )
		data:SetScale( 1 )

		util.Effect( "AirboatMuzzleFlash", data )

Just attach this to your proper events.
