Details of the issue:
Can't add shaders or game crashes at start up
Launcher Version:v1.4.11
Modpack:Direwolf20 or FTB Infinity Evolved
Modpack Version:2.3.5
Log Link:Details of the issue:
It appears that if I add any mod not included in the modpacks, the game will crash during start up. I'm trying to add shaders (and optifine if possible). My computer specs are plenty good so I know thats not the issue, its acting similar to out of RAM crash but Im giving it 12gigs, which should be overkill.
