As D_F_N, the weapon wear and dirt are implemented when the enemies are created by the engine, and so far I havent figured out how to separate Soldiers from bandits. There is a setting in the BlueSunMod,ini where you can set the max % of wear and dirt, it will be set at 25% as default.
The enemy bodies issue is out of my reach, but I use a little trick I'd like to share. Throw a grenade near the dead bodies and if you're lucky they'll shift position from the blast. This tactic has saved my bacon several times
As the proverb goes, when it rains it pours. The Blue Sun team has gotten a new 3d modeler, Geroj, and he has made several new weapons. Carkiller from the HLA team sent me some of his new models and then this weekend another member of the HLA team, cyr-v sent me even more. As it is now, 35 new weapon has been added and more is on the way. I hope I'll have time to implement and test them all before the next release.
