Optifine broken textures

[tzeapa]

When I install the optifine mod on FTB, the mob, player and chest textures are starting to mess up. To fix it i need to restart the game, but then it begins again. I tried to reinstall the mod, the game and even the operating system.

It's a known issue with optifine. It doesn't play nice with several mods. In the instance I use it reacts badly with Metallurgy, causing the same problems you report. I don't know what causes it specifically, but you're not the only one who suffers from it.

I get the same thing. So, it's Optifine's fault?

Disabling portal gun fixes it.
