Erindale: "I know some people aren't fans of a purple simulation zone..." also Erindale: *makes it more purple for the rest of the video* :D

I love how simple doing this has become after simulation nodes. Just a couple of blur attribute and storing inside the simulation, while the rest is the cherry on top. Really shows the potential of this node system.

Simulation nodes are so great, love seeing all the creativity in the community! Hopefully this means we will also get for loops soon

Thank you for making learning the hard things fun and approachable. 😊

Yet another stunning tutorial! Well delivered and easy to follow! Thanks one again!

Thank you so much!!! I have been trying to get a customizable version of reaction diffusion working in Blender for months. You helped a lot

Erin is the GOAT. Thank you for this I'm excited about simulation nodes finally being part of the main branch, its gonna be awesome seeing what everyone does with it.

Wow this is soo cool! You and Seanterelle are really pushing the boundaries for that organic generative content 🔥🔥🔥

Just BRILLIANT. Absolutely BRILLIANT. Thank you! Dg

Brilliant explanation and one of the few vids I’m still able to keep up with ;]

You're the best! 😍

This is very interesting! It looks like reticulation that you can get in photographic film. Simulation nodes are interesting too, that it can affect the material and the geometry.

Reaction diffusion? More like "Really cool information!" 👍

This is so cool, always loved programming things like this but they were super slow to run because of the laplacian smoothing operation, the blur attribute is so fast, cant wait to see what other nodes are added in the future, thanks for your tutorial.

There's a movie called Vivarium that I noticed using very similar effects on a TV screen in the movie, so that kind of brought me back to this

26:58 Basically, the simulation zone can have constant inputs, varying inputs, and varying outputs. Varying inputs come in through the Simulation Input node, and varying outputs exit through the Simulation Output node (and are also fed back to the Simulation Input for the next iteration). Constant inputs go direct into the simulation zone, bypassing the Simulation Input node. And you’re not allowed to have outputs that bypass the Simulation Output node.

4:57 Notwithstanding that Named Attribute node is outside the simulation zone, if you follow the chain of nodes to the right to find the geometry from which the attribute value is taken, you get to the Geometry input that is within the simulation zone. So that Named Attribute node is effectively also within the simulation zone.

Absolutely jaw droppingly amazing. My big inquiry is less about the actual process, but more about how one comes to have the knowledge to even approach the development of the technique to get to the result. Do you have a scientific background, like in molecular physics? I fell down a mathematical rabbit hole one day reading about molecular flux etc, trying to make sense of the concepts and equations that are just way too advanced. Now, bringing those concepts into a 3d environment wih a node system... it boggles my mind. Where and how do you start? Anyways i am defintaley messing around with this when i get home, even thoughi feel i am just following a technique blindly without fully grasping the why and the how of it. Anyways. You're one of the GOATs.

Great video as always. Here's a video idea and community favor that I would like to ask for - make a video about every node in geometry nodes. I've seen some video but I feel yours will be the best one in terms of clarity, example and concept. You can also then expand over the video with a full series about newly released nodes. The community really needs something like that. There are so many nodes and so much to do but we do not know every single node's purpose. It would be very helpful to have a video about it.

That was amazing as always! How do you even come up with these good ideas?? and how long does it take to find the best possible way to solve it? (in this case, cuz I know it varies from project to project)

This is awesome! How do you get it to loop, like in the intro? I tend to make seamless loops and haven't been able to use it because they never loop... (and no tutorials explain how they loop) I was super excited because you showed it looping in the intro! But then completely skipped over that part!

Legendary mathematician Alan Turing wrote a paper about the theory behind this, back in 1952. I’m still trying to make sense of it.

Loved this tutorial alot! So fun to play wit. One question though is how do you control the simulation speed? Or perhaps I miss this somewhere. Thanks 😺

Hi Erindale, thanks for the tutorial. That was an amazing explanation. I have a question: I was wondering if I can use the texture and color info to create vertex groups in order to create a mask using the mask modifier. Thanks in advance!

Erindale = Daddy AKA the GOAT. Thank you KING !

When I connect Nmaed Attribute node to Store Named Attribute like shown at 4:56 in this video, the sphere surface in Object Mode remains black and doesn't change to show the texture (Blender 3.6.0 LTS). Any idea why this can happen?

Thanks! could you say some pros and cons of this method compared to the Tissue one?

Been a while since I've stopped by. Awesome simulation and tutorial. I had a question for you though. It's probably been years now, but do you know what happened to your procedural bridge video? I was trying to find it and it seems to have disappeared?

21:44 looks like the alien keypad from Obduction.

i am so far in the futchure it is 4.1!

Is it possible to fill a mesh with this reaction diffusion. Ive seem that a lot in houdini animations? Basically a volume texture?

Dude, you are a total Blender bad ass. I recently got serious about learning Blender because I'd like to share an idea, with like minded people, that would change the World in a way that places a higher value on human potential than money. What good is money if all your needs are being met? The Blender community is a perfect example of what can happen with open source sharing of information, and I have an idea that would take this type of cooperation into a new dimension.😉 We are at a crucial point in history where the current technologies available give the citizens of Earth, the opportunity, to end a system based on competition but on cooperation. Do you know in California the homeless problem will never end because there is too much money in it? The non profit organizations "Fighting" homelessness are making tons of money. This rat race has to stop and only a large group of free minded people can make it happen. Would you have any interest in collaborating your talents with mine? Where would we be as a human race if the entire education system worldwide wasn't totally corrupt and inefficient? You are a very good teacher my friend.😁👍 I'd love a chance to talk with you about a very practical plan to literally change the world, I believe you'll get the whole idea in a millisecond.

looks like brain lobes

Technically interesting, but not too useful. I'm used to better from Erindale

I can't get my values balanced 🥲
