Thermal series machines and Create brass + andesite casing textures missing with Optifine installed (This isn't an issue in other modpacks)

Try to change Mipmap levels back and forth. It Helped some people to solve messed up textures with optifine.

Another workaround is to install Optiforge along with optifine, that can help too.

But keep in mind, that optifine by itself is not doing well with modded. That issue can be unsolvable, since easily can be reproducable only by you.

Alright I've messed around with the settings and the cause appears to be both anisotropic filtering and antialiasing. Oddly enough mipmap settings had no effect
