I was bad as math and I decided to learn graphic design and 3d animation because I thought I would never have to learn math with that career. Now I have to do math AGAIN!

How cool is that?

Thanks Chris, you've really helped me to understand order of operations here! Had loads if fun👊🏾⚡

I know the mic quality isn't great in this video. The nvidia broadcast noice reduction was switched on after an update. Oh well...

Thanks so much for your time and effort making this tutorial. I'm a pretty veteran Blender user but couldn't get a grip on the simulation nodes, even after watching several tutorials. Apparently I needed your calm and detailed explanation to make some progress. ❤

Excellent tutorial Chris! Really love your explanations as you work through as totally helps me as a person who doesn't really get the math, but following along helps that understanding rather than just plonking down geo nodes.

Very easy to understand. Thank you for detailed comments of what you are doing

6:34 - 6:50. You test and figure it out instantly. That would be a day-ender toiling for me.

Hi Chris, Great tutorial. I like the way you explain everything that you do and why you do it. I also like the idea of subframes. It makes so much sense. What I did not understand at all was a step at 6:47 . When the the simulation not worked at expected you just added the location vector of the icosphere , which makes no sense, but made the simulation looking more evident. When I tried your setup on my system and I needed to do the same addition, but I was using Blender version 3.6.0. At the end the simulation looks good when you nuge the particles from the center to outside, but it looks not so nice when you nuge them into the center. There seems to be a bug in Blender 3.6.0 the causes this issue. I upgraded to 3.6.2 and immediately the simulation works perfect without the step (addition ) you did step at 6:47. I hope to see more such great tutorials from you. 👏

Thanks for your videos Chris. They inspire me to continue learning more aspects of Blender. Just this weekend I have been using Blender to do soft body sims for a lot of objects. Too many objects... The sim just never stabilizes. I ended up writing a Python script to do away with all the simulation and generate the image I want from scratch 😂

One of the best geometry Nodes tutorials out there

Really astounding! Thanks for sharing knowledge!

Thanks for your videos Chris!

thanks for your amazing tutorial. It takes me many improvements

This is a great tutorial, the level of detail you went into was at a good balance of not overwhelmingly complex but also not so basic the viewer struggles to understand - good job! I do have a question that I would be very greatful if you (or anyone here) could try to answer; I am trying to create a similar simulation to this, however I want the particles to collide with the boundary elastically and rebound changing direction (but not speed) in the process. I dont want them to be moved in the normal direction of the boundary surface but to instead have their velocity vectors reflected around the normal of the collision point. I have tried so many different setups using the vector math reflect node and a switch (if distance > radius, then use reflected velocity vector) the problem is instead of the particles bouncing off the boundary they just first slide along the boundary up until a certain point then stick there and shake back and forth - I have no idea what im doing incorrectly so any guidance would be more than appreciated. Thanks :)

Great tutorial, many thanks

Holy crap. This is rad.

This was amazing, thankyou so much

Amazing 😮

This is really cool

Awesome tutorial, I did it without checking your previous videos. I understand simulation is all about maths and calculations. I made an awesome music visualiser by baking the f curve to sound for the size of the orb, cracked up the particles numbers and it looks absolutely stunning. Thank you. I will tag you on IG when ready

Untill 11:42 i thought ...are you making the same Node setup as other in Tweeter.. but after 11:42 it became more interesting and I got new Knowlege with your help! Thank you very much!

this would be really cool for simulating those bioluminescent algae in the ocean

get it!

Well done sir, and thank you

Incredible :) Sooo cool :) That's why I love the virtual world :)

Impressive! Thank you!

Great! Thanks

I was following along and was getting confused why it wasn't working, I had the input nodes backwards on my subtract you made at 11:25, gotta remember that :)

Hey I was watching your first couple of sentences in this video and it made me think, Deconstructing other peoples files to learn how and why they work is an excellent and useful tool. Itd be cool to have a video where you choose some project file and then livestream as you figure out how it works, and think out aloud as much as possible, and then possibly edit it into a video about how to learn from a file.

Great tutorial! I prefer to use named attributes instead of piping a capture attribute node from the start to the beginning. This helps to keep the layouts clean. :) But it might be confusing, since you don´t see the data flow.

Awesome

sehr geil, Danke für das Tutorial.

incredible tutorial!!!

Bro can you make a tutorial about all vertex, edge and face nodes in geometry nodes I really couldn't find any great tutorials explaining them practically like you do in your videos please make a tutorial about it bro

25:47 Oh Yeah! I can see it! WAY WAY BETTER ! Awesome Dude! Your setup is the best currently! Excelent for Sand Renders... continue watching )))

very teacher-material.. i like the way you explain

I really appreciate this tutorial. I'm just wondering how people learn this kind of stuff?

Great tutorial, thanks! Is there a way to add a gravitational interaction? So that, for example, after a collision, all the particles tend to go back towards the collider. Would be very useful for planet collisions like Theia-Earth!

Hey Chris, great tutorial 👍 I'm a bit late to the party, but one question: when you try to determine if a particle is inside the icosphere, instead of subtracting the two position vectors and then calculating the length of the vector you could simply use one Vector Math node set to "Distance".

Great lesson! Chris, how to make the color transition smoother? The balls change their color too quickly according to the color ramp. How to make the color transition much smoother, not so fast?

How do I proof that I at least understood something? By spotting that you missed the later set radius of points instances to be calculated into the vector to to push them out of the big icosphere, hence they hug the border being half in. Thank you for the explanation. Great video. Reminds me that I think the capturing on attributes at each point is the hardest to understand, because you lose that context in the nodetree after some time. Most important feature to add is comment field for each node to allow documentation. In code you can do that, in nodes it is very difficult and I think an oversight from Blender devs.

how do you get the position of the particle from the 'distribute points on faces' node?

This is fantastic! One question... you were using multiple position nodes that were fairly close to each other. Could you have used the same one?

Awesome Tutorial Chris!!! Is there any chance to restrict the particles to only move on the X and Y axis (and avoid them to move into the Z axis?

grande crispy da Eraclea

can you make active ragdoll physics with simulation nodes?

how do you stop particles from moving in the z direction during the simulation?

Wouldn't it be possible to make a loop by having a loop index, that is output at the end of the simulation and increased at the beginning. So you can compare it with a max number and if the index is >= max number you do not do any calculation in the simulation. Now the big question is when to reset that loop index ? I suppose the simulation handles 1 particle at a time, so when the particle index changes, we set the loop counter to 0.

Hi, where can i get simulation branch PR104924

Hi, how can I scale the particles :')?

self collision 17:00 #bookmark for next time

Any one tried this with version 4 + of blender ?

i figured it out, but thanks for your reply! :-) kzfaq.info/get/bejne/ps94m9ak3ZrZgKc.html
