Z - Depth Distance fade using material nodes

This is a method for calculating a Z depth distance fade
effect using material nodes and drivers.

I’m not 100% happy with the MIST effect; it produces a transparent alpha which is not going to work for my style of compositing, it also seems to be “stuck” on a blue atmospheric color.

The method here (see the blend file for the TLDR description :wink: ) uses drivers and a control object to create a Z-depth distance fade using material nodes:

That is interesting. If you add a noise texture to multiply the mix factor you can make the mist more cloudy or even animated. Poor man’s volumetric.
