After some first tests there are some open questions and some ideas how to improve on the current implementation of the environment medium.
Unfortunately I cannot judge how difficult or time consuming it is to implement some of those features.
Cameras and manually created volumes:
1) When I manually create a volume in the scene do I still need to use a sphere with inverted normals and place the camera inside?
Example:
Underwater scene
Do I now need to add a sphere with inversed normals and assign it the same material as the water volume?
or
Is it in OctaneRender 3 enough to just place the camera under water?

Medium shapes - sphere, cube, infinite plane?
As far as I understand it currently the only available option for the Medium in the daylight environment is "Medium radius".
This makes me assume that the medium is generated as a sphere with a specific radius.
2) Would it be possible to add some more default shapes that the medium could have?
- Cube with the options to define length, height, width
- infinite plane with options to define distance to camera, rotation of the plane

Index of refraction for the Environment medium?
3a) When we manually create a medium and place a camera inside is the index of refraction actually used?
3b) Will it be possible in later versions of OctaneRender 3 to also set an index of refraction for the environment medium?
or alternatively:
3c) Will it be possible to assign materials to be used as medium for the environment?
Example Underwater scene:
Assigning a water material with a displacement map to an infinite plane defined in the environment settings would produce caustics in the whole scene.

I just made some test with the Volume. and I realize the light passes doesn't work here the file attach.
