cg_forceWeaponColor is a bitmask to force the color of weapon trails / beams / projectiles:
|8||lightning gun / Shaft|
Example: Set this value to 1 + 8 = 9 to force the color of grenades and shaft.
The color of the trails / projectiles are defined with the cvars:
- cg_teamWeaponColor <hex color>
- cg_enemyWeaponColor <hex color>
It is recommended to set cg_forceWeaponColor to 1 to force grenades.
