In reply to YOYOK9:
This worked for me. nice.
what happened to me before my sh** randomly broke:
I changed around the versions of better-minecraft-modpack from 13.5 to 14.5 and i didnt like it so i tried switching back, messed with the textures barely too and turned a shader on then off. then i found the new verson (for whatever reason) wasnt as good to me and also was laggy out of nowhere. it like crashed, broke, messed up, so i just gave up. turned my computer to sleep woke up today and tried messing with it and now it just doesnt work?
and this has fixed it for me. thank you.
