Maybe i’m getting this wrong.
But what is the Z input for if it doesn’t change the output of the Z Pass at all?
No matter what i do with it…
It’s data for defocus and vector blur nodes. Normalized version is used in other compositing softwares and can also be used as a mask to compose atmospheric elements, very similar to a Mist Pass. Yet you will get better results using camera depth of field at cost of higher render time.
Obs: There are more advanced compositing techniques using z-depth.

thank you for that in depth(!) explanation, but i was actually just wondering about the Z input of the composite node which does not change the output of the z pass even if you connect a black RGB node or something else…
