I have added the V-Ray Environment Fog as a V-Ray Atmospheric. It can already be found in the nightly builds.
The next nightly build (the one from 2015-06-23) will also include the ability to specify a list of lights to affect the environment fog.
Note that there are two flavors of the Environment fog :
- One is a global object that is created/viewed in the "Item list". This object can have gizmos and lights specified for it.
- The other is created/viewed in the Shader Tree and can be masked, so it attaches itself to a specific mesh layer.
Internally they are treated differently, and should be used in different situations. That's why I decided to split them
into separate MODO item types, so the difference is apparent.
The "atmospheric" version will correctly handle overlapping gizmos, and it will also work when the camera view-point is inside one of the gizmos.
The "volume" (shader tree) version will make the fog twice as dense, where its objects overlap. It also doesn't work, if the camera view-point is inside the volume.
But it will be faster. It should be used in case you want to replace the standard material fog from a V-Ray material.
Here is a comparison of how these two work with overlapping gizmos/volumes :
The shader tree(volume) fog is on the left, and the atmospheric(gizmo) fog is on the right :
