Here are some cloudy, foggy doodles I created during meetings on Zoom and Teams, some geometry deformed with twist and displacement modifiers in 3DSMax and rendered with volumetric scattering in Toolbag 4. I used Gaea to create a swirly landscape that I used to displace the top of the cloud geometry. Look dev and post processing in Photoshop.
This one was created during a call with the amazing folks at Mojang!
