This mod for Red Dead Redemption 1 makes wooden structures more flammable and the fire on them burns longer. Bullet and explosion effects are replaced with fire or gun related effects. The mod comes with an effects list file, combined into one, so you can replace any effect you want. You can open the fxmaterials file using Notepad++, press ctrl+F or ctrl+H and replace any effect, but always keep a backup copy of the previous file in case an effect doesn't work.
