How does the torch light up?

I took minecraft sildurs shader medium today. Because high and extreme fashion need too much power. But does that make a difference that the torch in the hand shines. Should actually be. And I don't think you need a mod for that because nobody has mentioned it yet. Does anyone know how to light up the torch in your hand?

To light up a torch in your hand, you need Optifine

Yes, I did the whole thing with optifine. But the torch stays like the night
