This mod for Red Dead Redemption removes bullet marks. Now, when you shoot, there will be no visible traces of flying bullets, which makes the game more realistic and can improve immersion in gameplay.
Installation:
Move the .rpf file to the Red Dead Redemption/game folder.
Or replace the files that are in the loose files folder using MagicRDR or any other archive tool of your choice.
The files that need to be replaced can be found in tune_d11generic.rpf/root/tune/settings/weapons/.
