- If some of the editing is weird it's because I used a tool to trim all the gaps of silence out and then didn't watch before posting. I guess let me know if you notice bad patches, and I'll stop using it.

Best intro tutorial for Simulation nodes btw!
how/where did u learn that?
I love these tutorials for intermediate users that assume basic working knowledge of the UI. Thanks
Idk why i plugged the position into the rotate node, it doesnt need to be there. I was just going fast and forgot about it.
1:15 - "Turns out you can kinda do a lot with that functionality."
LOL, understatement of the century! I love your style; no joke.
Great stuff! I've been putting geometry nodes on side, but watching videos like this give me the inspiration to dive right into it!
Thank you! So much golden info in one video. Love the long format
Please keep these coming! I love that you throw in some shading tips as well. Very cool stuff!
Thank you for this video, I'm getting plenty of inspiration to solve a few problemas I have with my particle simulation.
The things you say and the way you express them are incredible. The most understandable and clear tutorial I have ever watched. You have prepared a very nice resource for beginners. Congratulations.
1:47 - i have to pause the video before it even really gets started to say DUDE! I LOVE YOU! 😂
I'm embarrassingly new to 4.x because I only a couple of months ago FINALLY got a computer that can run anything past 2.79 ... I've been trying to keep up though. And now that I'm getting serious again for REALS - even with all the new advancements I spent most of the past two days fighting with the SAME particle system limitations and drawbacks that were there as long ago as 2.35... 🤬
In just the first few seconds you already showed there's possibly a way to do what I want that I never could. (guided particle systems with fine path- and timing- control.
I'm having more fun than ever! THANK YOU! 😻👍
I've learn so mutch watching this video, thank you !
very interesting. thank you!
amazing!
Thanks this helps alot
thanks joey
what if we wanted to make some points close enough to the start control point to a curve to be "sucked up", travel along the curve, and then "spat out" its end control point
Great stuff! The explanation of every node/technique with context of how they can be used really helped in wrapping my head around Sim nodes.
Do you know of any way to bake Geo nodes animations to keyframes? As in each instance becomes an object with keyframes on position, rotation, scale. Like the Cake Particles add-on for the old particle system, which I want to transition away from 😅
excellent
thank you joey, super helpful as always! how might i control the rate at which particles spawn? like if i only wanted 5 on screen at any given time
how/where did u learn that?
Yay
Can you skip frames inside the Simulation Zone ?
For example I want to spawn the points once every 5 frames instead of every 1 frame
i'm exactly the opposite, i put my end frame at 120 cause i hate pressing shift left click every damn node tree update i apply
19:11 - I think it's maybe a geometric progression?
So, if I wanted the points to be attracted to a complex mesh, how would I do that? It seems like the node set up is the points itself, whereas i'm trying to apply those points onto a mesh that moves. I'm a complete noob with geo nodes sorry
I showed that at 22:10
Hm? I'm trying to make fire but the points doesn't want to move up the way you made them do like in 10:00 and 13:00. what can I do?
If you can show me a screenshot on discord, I might be able to figure out what is wrong
why can't i find the simulation nodes?
Use version 4.0 at least
@@JoeyC-quel aw dang it! (several hours later because blender likes being difficult) ok, ready now. thanks for telling me!
we can generate it with geometry nodes I think
how do you know so much?
I look things up and practice a lot
Ever considered using Houdini given your skill?
Yeah, it seems great. It is just not a high priority compared to everything else I have going on right now.
