A predefined Mist effect always uses a vector from the camera view axis, doesn’t it? How can I give it a new vector of my choice?
For example to create a fog that changes its desity from left to right, not just simple from near to far. Or to give it a direction of a Spotlight then use it to tone the searchlight effect made by this lamp. Of course due to the distance from the light sorce, not to camera location again.
