Another instance where you are on point and right on time. I needed to figure this out today. I don’t even need to leave the house now

Thanks so much for this brilliant, well-paced explanation! It helped me a lot.

[VR-fnwp]

Really clear, concise, easy to follow. It worked for me. Best part is you made it short and simple. Looking forward to more 10 minute tutorials! Great work !

I really understood the difference between before and after using the ForEach node! Thank you!

[zoltanracz]

just what i needed for my project, thanks

[katevandeweghel]

thank you so much for taking the time to explain everything so well! i hope you make a lot more 👍🏻 always looking forward to leatning new options ❤

[Daibutsumusic]

This is beautiful! Thank you. I have an idea of what I would use this for too!

Very helpful cordial newbie friendly tutorial,
Thanks for sharing,

[TheDuckyD]

how can I do this but all the points connect a line to each other, which would mean each point would have several lines coming from each line

Please make some video on how to make texture move along the spline mesh. for game-like VFX wind, smoke etc.

[kunemann]

Thanks for the great tutorial!

Just a small tip: using *0.1 instead of /10 can be faster because multiplication is simpler for the CPU to process than division. It might not matter for a single value, but in larger node setups, the performance gain can add up!

Thank you so much for your content, it’s super helpful!

I have something I’m trying to achieve using Geometry Nodes, but I’m not sure how to approach doing it. I don’t think it’s super complicated, but it’s not something I’ve been able to figure out by looking up tutorials or messing around with Geometry Nodes myself.

I am doing a VFX shot where a CGI ship crashes into the ground. I did a physics simulation of this crash using a particle simulation program called Storm, to which I have an alembic file which contains only point data. I also have a mesh that I created and fractured separately. I have the fractured mesh and alembic point animation lined up with each other in Blender and what I’m trying to do is have the animation of the simulated points drive the position of whatever chunk of the fractured mesh is nearest to that point.

Would you mind me asking you how you might approach this? If you are unable or don’t have the time I totally understand and no worries at all! If you are able to, I can send you a .Blend file with the alembic point simulation and fractured mesh so you could more clearly what I’m trying to do.

Thanks either way and thank you for making helpful videos!

how would you make multible connections lets say with the nearest 3 instances?

[danicamino]

Muy bueno el tutorial. Lo único que sucede es que algunas de las líneas que se generan se duplican. Si hay dos puntos aislados, unidos por cercanía, el método hará una línea por cada punto y se duplicarán. No sé muy bien cómo se podría solucionar.

[MikeRadjabov]

And if I want to connect single point into multiple closest points? how can I adjust this setup?

Outstanding tutorial.
Keeping the video under 15 minutes (as you do) is a great idea. There's already enough here to go practice and acquire something useful.
May I suggest you retitle the video by replacing 'in Blender Geometry Nodes' with "With the Blender For Each Node"?
Among all the nodes used here the new For Each Node is the most important.
