How to render ultra-realistic looking models and textures in Blender? [closed]

I know I know, I sculpt a model, bake the textures >apply them and that’s it.

Come on, that can not be everything when it comes to ultra-realistic 3d models.

I have seen guys creating textures with applying 102381028310 stuff, like sub-surface scattering, then some extra layers of textures, once zoomed in, a user can see more textres that are like small and normally not rendered from far away.

Can you just make a list of such things that would not be included in the >bake them, difuse, AO, spec normal maps> apply them and that’s it.

So any extra technique that you know, please post it. Yes I know lightning is important but that is a whole different question. haha I probably sound a little bit irritated in this question, that is because I already asked in like 5 forums and no one is able to tell me some of the other techniques or whatever, so that I know where to expand my knowledge.
