It’s that time of year when we have to add snow to all manor of things, so i got my hands dirty with our favourite silicon overlord, chatgpt, and wrote a snow shader, good for snow, dust and ash type effects.
Enjoy!

Love your work. Thanks 
Polite feedback 
:
Is it possible to have some presets like the ones you are showing in your demo?
I am on a linux box and I can see some hard edge clipping on some snowflakes. I’d be interested to know if it is just linux or mac as well

Is that in the default setting?
i haven’t tested it on Linux, just on a mac, it might be because your flake size is too big,or too much softness, i havent really tested it to the extremes.
For dust just turn gravity right down and lower the wind to very little speed, then add some turbulence and make the flakes much smaller, the clump distance will prob have to be adjusted too, along with reducing the softness.
For ash, you can reduce the layers, reduce the gravity, reduce increase the softness a little and increase the clump distance, then just down stream composite over black and lower the opacity.

OK made some changes that should fix the clipping issue on Linux / Nvidia.

Missed ya buddy!

Love this! Thanks Ashby! If you can save some basic setups here for everyone! Snow storm, gentle snow, windy snow. calm snow….just a suggestion.
I don’t think the Matchbox interface let’s you save presets unless anybody has any ideas on how to do that
OK added a damping function to that we can now have higher values of turbulence without the flakes cutting off, also added per flake value/brightness variation.
