Here's another early access perk for you, a rather beefy video about how to make these animated dust particles with Blender. I considered splitting this one up into several episodes, but then I thought I'll make use of chapter points instead. In the YouTube description, you'll be able to click on a timecode and jump straight to a desired section.
There's a lot going on in the process, and practice makes perfect. I've included two scene files for you too, one that I've built during the video, and another one with 4 different particles that will serve as a starting point for another video that's coming soon.
I'll put this live next week, probably as a YouTube Premiere. If you have any questions, please let me know :-)
I've also got some written instructions here, and while I was writing the article I've generated another blend file that I thought I'd share with you too. Comes out a little different every time ;-)
