The system is one animation per set for all throwing weapon types, everything from frags to molotovs to throwing knives, its not possible to have anything more detailed then a simple generic toss. As for a belt fed LMG, I can probably jury rig something up that acts like it should, or at least at least looks better then having it static. But that said I'd only go through that pain in the ass ordeal for something truly special, I'm talking a fully modular M60 with fantastic models and textures made for F4, from the Vietnam model all the way to the E6 with as many attachment options as possible. That's the only thing I'd really be willing to try it for but the odds of getting that stuff are slim to none haha, so I wouldn't get hopes up. How would the MG3 or HK21E sound?
