Edge feathering on volumes

Hello.

C4D has an edge feathering option within volume objects that allows for seriously cool fog renders like this by station02:

viewtopic.php?f=5&t=70670

What would be the equivalent in Blender? Is it something that could be implemented?

Hi,

you can generate an smoke simulation and save the cache. Then you'll be able to load any OpenVDB frame and use it in your scene to simulate that kind of smokey fog (Use as Octane VDB option).

I'll bear that one in mind, Lino - thanks. Now what about edge feathering? :)

That's something that would be important to have implemented, but it totally depends on Standalone.

There is a cool workaround involving a simple plane in front of camera with a Specular material. The setup looks like this:

The fog can be easily moved back of forward to get desired effect

You've got to be kidding me... Tried this and within 5 minutes have sandstorms and god rays.

Increasing phase setting in medium node gives interesting results:
