i like the node groups thingy, it allows you to make tutorials about more complex stuff without needing to waste time explaining all these little things, so you can instead focus on the more important bits.
Geometry nodes is REALLY not artist friendly. This stuff makes a lot more sense in Houdini. I've been disappointed with it's implementation and progress. Maybe in 5 years. Why are we wasting hours building something that takes 2 clicks in other software?
@@apoc519 i highly disagree, i started as a literal pencil and paper artist and ive done ridiculous stuff with geometry nodes. my profile pic is also a 3d model i made years ago. geometry nodes is complex because its powerful. once i wrapped my head around the workflow i RAN with it, it should be mentioned that i had experience with shader nodes beforehand though.
If you got to moving the points and discovered they’re moving vertically, instead of staying on the surface, here’s your solution! It’s because the noise texture we used way back at 7:40 to set the initial velocity (v) attribute is three dimensional-it has a Z component. That means when we use these velocities to move the points at 23:53 they move vertically. When @BadNormals previews the velocity attribute at that timecode (23:53), you can tell he’s removed the Z component because there are no blue colors in the preview. Blink and you’ll miss it, but at 22:18 you can see a Vector Math Multiply node has been added, multiplying Z by zero to remove that component just before storing the velocity (v) attribute in the fluid grid.
The two issues most will get are Moving points vertically:- can be solved by 22:18 you can see a Vector Math Multiply node has been added, multiplying Z by 0 Flickering:- Animate Radius node group and remove multiply math node above Float curve Happy Blending Artists Thank you Bad Normals for the wonderful tutorial 🤩
Man i was about to sleep, accidentally i find out your channel and i’ve been watching your videos for 2hours.. someone help me i can’t stop watching 😫 you are a genius frfr can’t wait for the course
This is awesome! I followed a similar tutorial to create a 2D fluid dynamics simulation in Touch Designer a little while ago. I followed the tutorial to a T and was very pleased with the result but I didn't fully understand each component until watching this video. Your visuals are really awesome! I appreciate you taking the time to put this together.
Ok I rarely leave comments glorifying tutorials, but not even half-way through this one is on another level.. the humorous touches here and there are definitely the cherry on top !
Funny thing: when you were making the pressure calculation using iterations and you said that we started to see a pattern, it seemed to me like the pressure was more than just a pattern: it was the perfect negative of the divergence. So on a whim, I tried replacing the entire pressure calculation with just the divergence multipiled by -1, and it actually worked perfectly! :)) Another note: instead of adding/deleting points continuously, just fix the velocity in the border cells at 0. I did this by making a boolean attribute for edges with more than one face neighbor (so now border vertices are zero, others are one) and multiplying this by the advected velocity in the sim zone. This causes the borders to become walls, and the particles stay inside them. With these improvements the sim is even more performant.
you make awesome content! I was testing and the advect node is different from the one I downloaded, I just changed it to how it is in your video and now it works
When i want to bring in the Named Attribute dt nothing happens and the projekt stops working. Can someone explain me how it get the Attribute dt in my Projekt?
6:13 if you dont see it moving and you've been pausing and backing up to follow exactly because some actions don't get said, and you deleted your group output like he did before making the simulation zone - add it back and this should fix it
I really love how amazing your tutorials always are! I was just wondering how could I adjust the speed of the overall animation? I can't seem to be able to adjust it without messing up either the pattern or something else? Thank you!
Very cool. I've already used this to make some cool fluid animations. One thing I'm curious about: When it's updating the velocity properties, does it overwrite the same properties that it's reading from? It seems like that could add some inaccuracy depending on what order it's evaluated, which you could avoid by using some kind of double-buffering. I'm not sure if it does that automatically in the geometry nodes, though.
I think it is the time now blender people should use and make Premade node that are optimized becuase at the end everything in computer is code and libraries that we use knowingly or unknowingly. thats why my long-term goal is to shift to linux as well.
what if I want to add an object that goes through the field, and the particles interact with it? How would I do that? Should I add a geo info into the simulation zone?
You mention that Delta Time was not working. This might be due to that Delta Time (in blender 4.0) is 0 at the first timestep. So if you scale using Delta Time from the simulation node, you clear your velocity field. If I replace the initial dt for frame 1 by 1/fps it works for me.
Brilliant tutorial. I'm using this technique with multiple cameras, though, and every time I change the start frame to render a new shot, the simulation resets itself - it basically starts from having 0 particles, rather than having the particle count it would have if I'd started rendering from frame 0. Is there a way to add a "run-up" variable somehow that will run N steps of the simulation before it evaluates the first frame? I tried using a repeat zone with the mesh part of the geonodes setup (distribute points on faces, store og_pos etc) but couldn't get that to work.
that is next level shit bro, I doubt few universities in the world have this level of teaching method I seriously doubt it thanks for the great tutorial the blender comminuty is unbelievable I can't believe this is free!
Pagan, mul on ikka hea kõrv. Kuulasin ja mõtlesin, et natuke nagu eestlase aktsent. Aga polnud päris kindel. Mõtlesin, et äkki on lätlastel sarnane aktsent või oled hoopis skandinaavlane.

Hey all, quick question: How would I transfer this across files? As in how would I attach this to another model. I've followed the tutorial in my Goe Nodes Asset library file and am wondering how I would have them marked as an asset. Do I need both the Fluid object marked and the secondary sim tree marked as well? And do both need to come along when I use it on another model, like the face example our esteemed teacher showed off? Thanks sir, stunning tutorial, awesome work as always!
Yes, you still do the movement on a flat grid, but move the points to the surface later on, after the simulation zone. A good option is to use the raycast node and a set position node.
solving the flicker gave me even more flicker idk why I have to set radius (under animate radius) to 0.5 or so anything too small and it has the same effect as setting maximum age to 0
@@yoyo_cortex Thank you for your reply! I already did that but it doesn't change anything... I'm on 4.0.1. I triple checked all nodes but can't find the problem...
Are you sure all the nodes are as downloaded? Also, make sure the new points are set to zero for their radius, right after the distribute node. And make sure the float curve output is multiplied with the radius controller.
Увеличение и уменьшение точек выглядит как костыль. На первом кадре стоит найти точки сетки в которых дивергенция не 0, и потом в этих точках создавать новые точки или удалять старые, тогда жизнь точкам можно не ограничивать временем и она будет более интересна
This is awesome! I try to do the same effect in Touch Designer and failed. Now I made it! Still have a question: I try to change the size of it. So I change the grid. But the effect didn't follow. Are there any other node need to be changed? Hope to be answered! Thanks！
Hey, this is a bit tricky to do, since in this tutorial I don't account for the distance between grid points. So when the distance is 1m or 1cm the result would be actually different. That's because the velocity would be multiplied with a certain coefficient depending on the grid measure. I recommend playing with the resolution, but I couldn't personally get very different results with this one either.
You have to ad the ripple animation on a plane and then use a raycast node to project the points onto the surface of the ripple plane. Do this after the simulation of the points.
I am unable to follow along. For some reason my grid is black and white and not black and red and can't see the animation happening. What am I doing wrong? :/ edit: after a long time, I finally managed to understand it. thanks
actually now I do have a "precise" question >>> how to render this for exemple with a local render farm and B-RENDERON ?... how to cache the sim for the tools to render the images. ?... I just tried. and all images are empty... no layers. nothing. but works fine from blender using the render animation from the application... but would love the accelerate the render process spliting on other GPUS... thanks ;))

Particles aren't rendering in eevee. finished the tutorial, particles are visible in the workbench engine and cycles engine but do not render in eevee. does anyone else have this problem? How do I fix this?
i cant choose "dt" in the Names Attribute, all steps before are triple-checked. what do i wrong at 9:45? ua-cam.com/video/l_vnAz0Yo8w/v-deo.htmlsi=pYzyPI7jvQAKKFTr&t=585
If there is no dt, then it hasn't been stored and you're most probably missing the store timestep node group in the start of your simulation zone. Let me know if you got it working.
Actually the only part I thought was stupid is that you could control the radius with a division slider. After changing to multiply I think it's the best solution for this use case

I wonder when Blender foundation will start updating their physics simulation engines. Donors nowadays only focus on UI and render engines. I hope we see more real world physics simulations in Blender.
Hi, I’m very new to blender. I made it up to 6:22 where you try the animation. Mine didn’t do anything but I noticed that the advect on your video has a 4 on the right side and mine has a 2. I don’t know what this means but, could this be the reason why mine doesn’t work?
if you're following it exactly like i was and also doing things he doesnt say (common thing i've seen with blender tutorials so i've learned to keep an eye out), and you deleted the group output at 5:37, re-add the group output and connect it's geometry input to the simulation zone output.
I really don't know what we could do without you, look at that style of explanation, i wish we were taught like this in school and university. Relly thank you. 01:35
Absolutely insane. I'll definitely be coming back to this. So impressed. The instructional visuals were top notch and made the whole thing so much easier to understand. There are sooooo many free beginner tutorials on UA-cam, but so very few intermediate+ tutorials (I have several assumptions for why that this). This was great and helped me feel a lot more comfortable and informed about Stored Named Attributes.
I'd like to create a similar swirling texture, but with a solid material instead of points. Is there a way I could store the velocities of each point as a named attribute, and then use the result as a vector map in shader nodes?
i like the node groups thingy, it allows you to make tutorials about more complex stuff without needing to waste time explaining all these little things, so you can instead focus on the more important bits.
If this gets generally positive feedback, I'll continue with that in future as well

How far away are we from performant cloth and softbody simulations using geo nodes?
Those are possible to do but I'm not sure this is the most optimal way. I suppose blender devs will add some more generic physics nodes in the future.

Google for simulation nodes cache. The cache gets stored into a folder and this needs to be sent to the render farm as well.

did bad normals invent the naviar stokes equations?

Yep, I'll send an email about the course in a few weeks. This video took so much time I could only focus on that
@@BadNormalsYes, i could tell, Thank you👍👍 This video is awesome
Particles aren't rendering in eevee. finished the tutorial, particles are visible in the workbench engine and cycles engine but do not render in eevee. does anyone else have this problem? How do I fix this?
You need to instance some geometry, like ico spheres on the points for them to work in EEVEE. But it can get heavy.
Hi , Can you check if your fractal machine addon is compatible with Blender 4 , i have dropped a DM as well .
Yep, I'll check today
hey, i can't find the advect node in blender 4.0 do you know why?
Download the file from the description, it has all the nodes you need. They are custom node groups and not included with blender by default.
My brain is just to small for this :(
i cant choose "dt" in the Names Attribute, all steps before are triple-checked. what do i wrong at 9:45?

If there is no dt, then it hasn't been stored and you're most probably missing the store timestep node group in the start of your simulation zone. Let me know if you got it working.
@@BadNormals I'm having the same issue in both blender 4.0 and 4.1, even having Store Timestep node group added. Crazy bug
Did u fix this problem?? Im stressed out of this😢
@@dharmaratano6508 nope sorry
you can’t say you did something in a stupid way and then show the exact solution i was just thinking of 😞
Actually the only part I thought was stupid is that you could control the radius with a division slider. After changing to multiply I think it's the best solution for this use case
hello ! thank you very much for your sharing good vibes !. >>> I stumble upon this little visual problem > using blender 4.1 alpha. and trying to link the Named Attribute to the Value ( VIEWER ) . was actually not working, not showing for example the nice RED.YELLOW.RED.BLACK color of the position attribute for example. >> was stuck for a bit trying to stick to the speed of your comentary in the video :)) HAHAHAA>. and even went on blender 3.6.5 to check if there was any potential bug in the beta 4.1 ...>>> well no ... same issue... >>> THEN > I TRIED >>> RIGHT CLICK on the ATTRIBUTE (node part thing) of the box :" Named Attribute" > and found this >>> (0) Link to viewer >>> AND BIM BAM BADABOOM >>> it works !!!. ouf!. >>> well >>> this is a note maybe to blender dev team... don't you agree this should work also by draging the link.node.rope.wire thingy thing to the Viewer box . it should not ONLY work when I right click and use this "hidden" function call (o) Link to viewer.. voila > my humble respectfull opinion ;))) cheers! and MERCI BEAUCOUP !. yann
Merci pour ton commentaire!
I wonder when Blender foundation will start updating their physics simulation engines. Donors nowadays only focus on UI and render engines. I hope we see more real world physics simulations in Blender.
the whole geometry node and simulation nodes are the building blocks for the physics simulation engine, I guess.
Hi, I’m very new to blender. I made it up to 6:22 where you try the animation. Mine didn’t do anything but I noticed that the advect on your video has a 4 on the right side and mine has a 2. I don’t know what this means but, could this be the reason why mine doesn’t work?
if you're following it exactly like i was and also doing things he doesnt say (common thing i've seen with blender tutorials so i've learned to keep an eye out), and you deleted the group output at 5:37, re-add the group output and connect it's geometry input to the simulation zone output.
I really don't know what we could do without you, look at that style of explanation, i wish we were taught like this in school and university.
Relly thank you.

Absolutely insane. I'll definitely be coming back to this. So impressed. The instructional visuals were top notch and made the whole thing so much easier to understand. There are sooooo many free beginner tutorials on UA-cam, but so very few intermediate+ tutorials (I have several assumptions for why that this). This was great and helped me feel a lot more comfortable and informed about Stored Named Attributes.
I'd like to create a similar swirling texture, but with a solid material instead of points. Is there a way I could store the velocities of each point as a named attribute, and then use the result as a vector map in shader nodes?
