Heads up, some viewers wondered why Cycles doesn't work to render the lines. Oddly, the orbs had color in Cycles, but the lines didn't. While investigating, I promoted the Orbs from Instances to Mesh using Realize Instances, changed the Orb shader to read the 'color' attribute from Geometry instead of Instancer, and it BROKE in Cycles. Quick web search reveals there is an open bug in Blender that renders colors black in Cycles when the attribute name 'color' is used on vertices. I've updated the Gumroad file, but if you want to fix your own project, the fix is to change everywhere you have 'color' as an attribute name to something else, even 'colour'. Cycles will work after (though you'll probably want to add some Glare in the compositor). Cheers.
For all those using Blender 4.2 (or higher) you cant use the "Bloom" effect in the Render Settings. Go to Compositing -> click use nodes -> and set a glare node between the two nodes -> set the menu from streaks to Bloom -> I recommend to set the mix to -0.9 to get the old fancy bloom look.
Such a great tutorial thank you for sharing this. Commenting about your question at the end: I get overwhelmed learning geometry nodes sometimes because I learn so many new nodes all at the same time and even though I can reach the result I don't think I'm really grasping the understanding about what I'm doing. These detailed in depth walk throughs are really helpful!
I'm glad this was helpful. And thanks for sharing your experience. I know the feeling-I've definitely followed tutorials in the past and felt overwhelmed. Many show the how but not the why. I'll keep your comment in mind as I make more tutorials for everyone.
Thank you. Glad to hear it was helpful. With all the videos you could have watched, I genuinely wanted to say thank you for taking the time to watch this one. And especially for taking the time to leave me a comment. I really appreciate it.
the tutorial is fantastik, the resolution scale is better. thank you (maybe only a little bit more zoom on the nodes, but it's already readable like this, thanks.)
Since the Noise Texture has been reworked it now has the Normalize option. If you would disable that, the output no longer ranges from 0 to 1 with an average of 0.5, but from -(detail+1) to detail+1 with an average of 0. So you don't need all that math to center it (only scaling maybe if you want to increase or decrease the offset effect).
Thanks so much for this excellent tutorial. Is there any way to attach text to each orb? Sorry if this is a dumb question but I'm pretty new to Blender. Thanks!
Great question! Take a look at my other video here to see how you can add text at different positions. I think this should help: th-cam.com/video/DQ1FBD6K0IE/w-d-xo.html
@@TiFiDesign That's brilliant, thank you so much. I just need to work out how to replace the numbers with text from a list, I'll keep you posted. Thanks again!
This is really strange. EEVEE works fine, and the orbs work in Cycles. Somehow the lines go black in Cycles. Disabling the Set Material on the orbs, the scene is completely black. I'm still trying to debug (will be a good learning lesson for me). Still scratching my head on this one.
Hello sir, thank you making this tutorial. I have a question as a beginner. If I wanted to make the random shape turn into a precisely a cube or a sphere (wireframe alike), what I would need to do? Anyone is free to point me to the correct docs or videos on the topic.
Hmm if you mean how to turn the plexus into an organized shape, that I’m not sure how to do really easily. If you had a cube to begin with you could use a set position node, take a Position input and plug it into a mix vector node, then plug a random value into the other vector input. The slider then would shift between the cube and the random points. That could be a good place to start.
Repeat Zones are designed to not be multithreaded, so you're geonode setup will quickly get slow when more orbits are added. On the Blender Science Discord Server we just discussed faster approaches, which can be e.g. achieved with the "Instance on Points" approach. Here's the blender file: discord.com/channels/940526858800336936/1104836157516284034/1262548263890845759 The Blender team has plans to have a 'foreach zone' in the future wich can run in parallel but it isn't there yet.
Thanks for the heads up and taking the time to circle back with your finding. I studied a way to optimize this until it finally clicked and I’m blown away how much faster it is.
Awesome content! Are you on the Blender Science Discord server? A few days back, we had a conversation in the #geometry-nodes channel about exactly this idea, and I think you came up with a great solution to it!
Heh, that's good timing! No, I'm not on the discord, so the timing was totally coincidental. Be sure to share the video in the channel! I'd be interested to hear how others improve and iterate on it.

i love ur clear logic and great voice, they makes everything much easier to understand

such a good and clean tutorial. subscribed😃
Thanks for the compliment and the sub! Welcome to the community. :)

Thank you, I’m glad it was a better scale. I’ll see what a 1.3 scale would look like as well since this was 1.2.
This was fantastic, thank you for sharing. Liked & subscribed.
Thank you very much!
this was great. so helpful
thx bro

How to Laser impact geometry node
This is something I plan on playing with and sharing as well.
thank you for this insane tutorial. Could you explain why it seems to does'nt work in cycle for lines ?
Hmm I wonder if the radius is too small and the lines are too thin. Have you tried increasing the radius of the Circle Curve?
@@TiFiDesign yes i did it but nothing change. i downloaded your file to compare and same probleme. Is it from main setting in blender?

Did they add the repeat zone in the latest version coz I haven't heard of that node yet
It's pretty neat! Looks like it goes back as far as 4.0.
Great tutorial! The fact that you sound like Elon Musk makes this tutorial feel 10x smarter as well
Thank you! 😊 I’m glad you enjoyed the tutorial.

what Blender are you using? The Equal nodes towards the end is not a node I can find (I'm using 4.1)
Hmm can you find a Compare node? You’ll want to add the Compare node then set it to Equals.
Thank you for the guide! But I can't implement the line color in Cycles. It only works in EEVEE. Can you give me some advice?
My first guess is the Curve Circle radius may need to be increased as it may be too thin.
@@TiFiDesign Increasing the radius didn't affect anything. The issue lies elsewhere. (4.2)
