Fog Bounding Box

Environmental Fog is great to create a sense of atmosphere, however it can also slow down render times significantly, as well as be hindersome when its only needed in a specific area.

I've created a small and simple setup to restrict the fog to a bounding box which you can easily drag and drop and resize using a cube object. You can also adjust whether and how much the fog should become less dense towards the top of the cube, which mimics how fog dissipates in real life.

The setup is free to use, though it would mean a lot to me if you support the work I share if you have the ability to do so; even if its just a little.
In any case, have fun and keep on creating!
