ReShade (graphics enhancement) v4.2.1
ReShade is an advanced, fully generic post-processor for games and video programs developed by crosire. Imagine your favorite game with ambient occlusion, real depth of field effects, color correction, etc. ReShade provides an automated and general way to access color and depth information (the latter is automatically turned off during a multiplayer game to prevent use), and all the tools to make it all work.
Setup:
1) run the application (ReShade 4.2.1.exe);
2) choose the path to the game (the standard path is C: \ Program Files (x86) \ Steam \ SteamApps \ common \ Spintires MudRunner \ MudRunner.exe)
3) select “Direct3D 9”;
4) load the standard effect and click “OK”;
5) start the game and press “Shift + F2”, press “+” and touch “shader”, select the option from the “shader” that you want.
Works in multiplayer. SpintiresMod.exe supports ReShade.
