This video shows ambient ground bullet hits at the front. They work, in essence, like the flak does in that they are only cosmetic with no actual damage associated with them. The effect will render the closer you get to the ground, as if soldiers are taking pop shots at you. There are no tracers associated with the effect and, like the ambient flak, they are centered around the player's POV.
Here three more stock ground explosions and a low level of battlefield flak have been added to the front line ambiance.
This video shows Summer/Autumn Front Line trenches which have been colored chalky. Textures for all trenches have been reduced in size too. Bomb craters have been made invisible because of flickering. Includes all the mixed Ambient Front Line Ground Explosions and Front Line Flak set for mild intensity.
Everything was tested in Single Player with 'Mods On' mode! If you have any questions or suggestions, or are interested in tweaking the files, please let me know! Thanks!
