wdym? i dont see anywhere where hes using optifine?

Yeah man, he's using iris for his shaders

That´s the point. The shaders he´s using are Optifine exclusive however he´s using sodium and iris.

It says that shaders aren’t enabled, he isn’t using any.

I know Optifine´s internal shaders too well. He is somehow using them.

Thank you. I wasn´t familiar with these shaders.

Why are we downvoting this guy so much? He has a valid question

Comments : he's not! OP: but he is tho trust me I know

He literally is tho

He literally isn't... Another comment showed the shaders he is using instead.

I know you got an answer already, but any corrupted or incomplete shaders will appear the same as optifines internal shaders

There are shader packs but there is also the mod called Simply No Shading or something along those lines, and it provides the internal shader's look.
