Had a little time on my hands and wanted to test out the vdb sky clouds I purchased. I'm trying to improve my lighting approaches at the moment without going full panic and trying ALL the hdri's and then resorting to early evening corona sun & sky. I'm really digging the results and the atmospheric lighting the clouds help accomplish while casting accurate shadows based on sun position and shadows from the clouds. I'm a wee bit excited about the result and haven't bumped into this topic yet on the forum so I hope this may be helpful to someone.
Some of these are straight from the interactive frame buffer, others are rendered and denoised so the quality of the renders aren't consistent. Also, no post-processing outside of the frame buffer tone mapping.

I did this so many times :- D
This is pretty cool, wanted to play with VDBs as well since Corona4 fixed the overlapping volumes.

The worst part is doing that on an uninspired project hoping for a glimmer of inspiration from the lighting and getting bubkas in return.
Have you played with the grid volume before? I am trying to get those cotton candy puffy clouds look out of these in the daytime condition and to no avail. I've been able to achieve the look with volume mat and geo but not with a corona volume grid.
My settings are attached below in case anyone has any input.

Can you post what you are getting with volume mat and geometry and what you are getting with the grids?
Maybe you should try enabling/disabling the channel color mapping for absorption, or try adjusting its curve. You can use it to, for example:
- create something that has a hard layer on its surface and becomes more transparent inside
- create something that has a soft outline, and becomes more dense in the inside
