Chiseled-me, BetterFPS crash.log

Was trying to add chiseled-me to a Hexxit 1.12.2 pack that I got from Twitch. Did some binary searching to narrow the incompatibility down to this mod. Did my testing with only the two mods above and caused the crash.

Oof, might be same as with OptiFine - some rendering incompatibility, there is a probability of it being unfixable (well, I mean hard enough to fix to not bother trying).
Will check anyway.
