Not an expert, but this seems really useful for realisticer walking without having to do a water or practical sim!

it's pretty exciting to have loop functions inside GN, I'm waiting until it matures a bit to get into it since I feel like the workflow will change

This is roughly the same idea as the Solver Node in Houdini, and using it to fade attribute transfer attributes overtime. Incredibly useful for doing things like footsteps or things pushing the ground up from underneath, and of course WETMAPS! It's great as well that you can move the object in the viewport as it's calculating, as far as I know Houdini still can't do that.

best explanation of the whole setup by now! Thanks for keeping it simple and making it easy to understand! Now I got to actually use that :)

Hi Chris nice to see you again, I will never forget that the first video about Geometry nodes was yours one, explaining some simple things. Unfortunatly, about the Simulations Nodes is not the first, but you stay in my mind any way. :). By tha way, nice intro to SN. Thank you.

These nodes are really great, they are the loop nodes we needed! For the moment I made a procedural disolve simulation node groupe inspired by the classic houdini projet, next I will work on a rbd solver

From the top of my head, 2 things I can use this for. Interactive water with falloff, and fire!

Well done Chris, great Turorial as ever, Broken down and simple introductions are useful. Bb19 is doing great things! (it's now named Cartesian Caramel)

I spent the last month learning scripting because I was so frustrated that there was no way to access values from a previous frame in GeoNodes. This is going to be very nice.

well i am excited for it as well, this demonstration of a "dynamic paint modifier" geonodes version is actually really interesting, giving the power to the user to acquire the data "as is", what were other awesome uses for dynamic paint? maybe we can try replicating some older functionality of dynapaint for insight? i'm new to 3d software as well

A fun challenge for you: Create a Geometry Nodes system that automatically orients a caster wheel as it is moved. The general problem is you can't rotate it based on the direction, because it instantaneously flips on a direction change. One way to make it look good is to create a cylinder and parent it to the rotation pivot of the caster (not of the wheel, but the vertical pivot of the whole assembly). Then put a sphere inside that object. Move them both down to the same level as the wheel axis. Now make that a rigid body simulation so that the sphere stays in the cylinder. Have the vertical orientation follow the sphere. You have to get the sizes right for the best look, but that's the basic idea. There are a few ways to accomplish it that work in real-time also. I created a single hair with an object at the end of the hair, and that created the drag needed. But that's not ideal. I'd love to see a couple geometry node solutions. I'm guessing the raycast node could accomplish this. Or maybe set the position of a point to be based on the stored position After the position has been set so that if done in a simulation group would always set the previous position, causing the object to "drag" 1 frame behind? That worked in animation nodes, but it was fairly time consuming to set up. I'm curious what you could come up with. I always see simulation nodes as doing things like particles or complicated organic lightning looking things. Being used basically as a rigging tool would be interesting.

How awesome! thank you for sharing this video. Great setup!

Chris nice to see you again!for some reason I haven't seen any of your Tut's in my time line?? happy to see you're still on it! Kind greetings jan

I like how you explain everything you do. I find a lot of videos where people just say what nodes are connecting but not why. I can replicate what they do and get the result but I need to know what I'm doing and why. That's exactly what I find in your videos. Thanks!

This kind of makes sense , so its really just value based interpellation from one scene frame to another .It seems like its could just be one node with a before value and after value and a 3rd input and output geometry and attribute but I obviously dont understand the variety of potential use cases that would dictate it needing to be 2 nodes , it will be fun to experiment , since I only played with it based on a default cube experiment. I really wish i had a overly simplified unicode diagram for each of the nodes ,so I could understand what they do better, as their descriptions can be vague and the documentation can be limited with examples or overly opiniated which makes it hard to think of the possibilities of use , thank goodness they have great error handling to make them easy to just splatter down and try different combinations and placements to unerstand how they can work for us . My biggest real gribe is that everything is hidden in popup menu and there are no icon toolbars to quickly just drag and drop with visual descriptions for fast testing and iteration of the trees , just a early gui limitation for now but Geo nodes are really useful for visual composition and sharing for people who dont feel like mastering/learning python libs and api's .

Everytime I come to this channel I remember that new's anchor that loses it when he covers a story about Chris P. Bacon, The Pig. 😆 Thanks for the tut Chris!!!

You can now grow corrals with mesh to volume, volume to mesh trick

Cool!

¡great video, Chris!

As always, awesome video by Chris P Bacon

Is there a way to "spill" falloff when all I have is random distributed points? In other words I'm trying to find a way to unclamp looping this falloff so it could grow from pointed location but not on mesh (bbn19 showed how to make this on mesh with interpolation points and faces) but on distributed point in volume.

Thank you so much, Chris! This is an amazing video. Question: How would you go about if you'd had multiple objects? E.g. multiple monkeys around the surface. How to show a heatmap based on each element's proximity?

Thanks for tutorial

Hey Chris the viewer node works in geometry nodes now, you don't have to use shaders to visualise the values anymore.

Is it possible to use simulations in geo nodes but for weight mapping with a similar technic?

Liked the video just from the intro😂 good content

I am downloading more than 2 blender in a day.

Smaller scale but still physically proper molecular dynamics simulations could be done. With forces from potentials not only for changes in distance but also changes in bending angles and dihedral angles. 🤤

Chris your videos are always so educational, thank you! Is it possible that the Mac (intel) build of 3.5a is missing the simulation nodes? I don't see them. Anyone know?

Can we export this node into Unreal Engine ?

hi Chris, could you please produce a short tutorial about how to make the colorbar from data in Blender.

I am waiting for blenderto integrate fire ,water ,rigid sims into geo nodes

I don't normally have to patience to stop any blender node tutorial, but the way you explain is soooo frictionless

It's a nice feature but i still didn't figure out how to loop it perfectly

If you're going to do a "loop" simulation node, why does it have to be linked to the animation?!?! Just add a socket value for number of iterations and loop it that many times. It would be immensly useful. Instead the animation loop is kinda useless for static things like procedural hard surface models. I dont get it... It seems to me like they did huge work for only 5% of benefit

very cool
