Hi!
After all these years i found a method to easily make 3d fog-like effect using only the built-in features of AE.

So: you place your 3d layers along the Z axis, usea proper camera (not a necessity, but useful) and place a simple point light and adjust the falloff radius and feather.
That’s it, the light’s falloff shades the further layers.
