I have a problem with a lightsaber glow

[Bete]

After loading a MOD (e.g. phatMod 1.0) it occurs a few problems with a lightsaber's glow color during the game in MP. The lightsaber looks strange (around ligtsaber glow appear strange texture) and when I use a lightsaber then appear a n inscription :
WARNING :RE_AddPolyToScene :NULL poly shader

I would be very thankful if somebody explain me hat"s happen

This might be a case of the mod not having all the files it needs to work properly?

I think PhatMOD is a compile of Jetpack and JediMOD 1.2 isn't it? Do they work fine individually? Do you get this problem if you start your own server (using PhatMOD) and try playing?
