This week I followed a rabbit hole that led me to rediscover some projects I’d previously not liked, but now they have the potential to be what I need.

Another update and a look at some interesting resources for learning to take astronomy data into Blender for visualization. It’s how the magic gets made!

I saw this on my YouTube subscriptions feed last week. Very cool stuff. There is a good blog post on using the add-on as well: https://darkfallblender.blogspot.com/2021/03/blender-add-on-shader-library-version.html
Downloaded the python script from the Pastebin link provided in the blog post . Then installed the add-on through Blender Preferences.
The Shader Library is accessed through the 3D View. If you don’t see the tabs on the right, hover over the 3D View and hit the “N” key on the keyboard.
There are several shader types and options to choose from.
The add-on creates the node tree for the shader. This is a great way to quickly see what node trees can do without creating them from scratch.
I added some compositing to get a nice glow in Cycles.
Have to separate out the Environment (background as set up in “World” panel) and blur foreground alpha separately from the image to get that nice glow.
I always look for a Cycles way to make things glowy since I ultimately use fisheye for use in the dome. Eevee is super fast and that bloom is wonderful, but it’s a no-go when rendering straight to fisheye.

Had a bit of fun making videos to celebrate in the weeks leading up to the Mars Perseverance landing. This one was one of my favorites.

So I spent my morning digging into a tutorial by Chris P on YouTube building a lovely Plexus Effect using Blender and Animation Nodes. There were a few stumbling points due to the tutorial being for slightly older versions of both, but they weren’t so different as to be a huge problem. And if I were more practiced with Animation Nodes it would have been much easier to figure out those differences.
My resulting video isn’t a super high quality because it was rendered for upload to Odysee/Lbry. I don’t know if there is a way to embed as there is with the other video players out there.

Another fine video tutorial from Ron Proctor!
