Me and my friend just got build craft and we have the same mods but my pipes and like half the other blocks are invisible, he can see them but I can't. Even when I don't use a texture pack they're invisible.

Do you have optifine installed? If so can you try disabling antialiasing?

I've disabled antialiasing but still don't see any pipes texture. I'm using BuildCraft 7.99.24.6 for 1.12.2 and OptiFine HD U F5.

Screenshots just in case

I tried to disable anisotropic filtering and now it's fine
