Tutorial: CRAZY 3D Flow Fields in Blender 4.2!

[@PiginaCage]

Hi daddy thanks for the tutorial, I didn't understand it but I enjoyed looking at you.

[@mtranimation]

You're very welcome! Sometimes by just watching you learn the most ;)

[@dickie_hrodebert]

That intro was Hollywood level. Amazing Tutorial.

[@mtranimation]

Thank you so much! :)

[@PPKeyframes]

Pretty awesome tutorial here! I'm curious, would there be a way with dynamic painting to alter the noise texture to make it so the flow field would, let's say, go around an obstacle, like Suzannes Eyes for exemple. or if we'd want to make a river with that technique and have the flow go 'round a rock. Thanks for that tuts. Pretty great and easy to follow

[@man_art_man]

Very very interesting and as usual so clear explained! Thanks !

[@mtranimation]

Thank you so much! :)

[@vstreet7583]

Just BRILLIANT! A great technique and stunning effect. Thank you so much for sharing your knowledge. THANK YOU! Dg

[@mtranimation]

Thank you so much! Highly appreciate it :)

[@vco7285]

Just completed the tutorial. Now I`ll make sth to test it and I'll probaly post it on ig. Thanks for the tutorial!

[@mtranimation]

You're welcome! Let me know when you have the results!

[@pZq_]

Great tutorial! Thx 🧡

[@mtranimation]

Thank you so much! And you're welcome :)

[@axaneco]

Brillant as always, i do LOVE your tutorials. There must be so much hard work just behind the scenes in producing it. Especially the intro was - again as always - so high quality, really amazing. Thank you so much for all the effort, keep it up!

[@mtranimation]

Thank you so much! :)

[@johnmitterer5672]

Very cool! another winner! Thank you

[@mtranimation]

Thank you so much!! :)

[@Binarnik-Linux]

[@mtranimation]

Thank you so much! And you are very welcome! :)

[@FrancoDifilippomicro]

does anybody knows how to hide the monkey and keep the lights flowing? like a transparent volume... excellent tutorial! thanks!

[@MyntRoom]

Crazy tutorial, loved it!.

[@mtranimation]

Thanks! Glad you liked it :)

[@АндрейЛопатин-и1у]

Thank you very much man!!!

[@mtranimation]

You are very welcome!!! :)

What is the song at the beginning of the video? Need to add this to my playlist asap Also loved the tutorial, was very clear and extremely helpful!

[@youmix2664]

AWSOME! Great video

[@mtranimation]

Thank you! :)

[@derridastone]

YOURE INSANE, I mean it. You're INSANEEEE!!!!!!!!!!!

[@azizal157]

THANKS ♥

[@mtranimation]

YOU'RE WELCOME!!!

[@danialsoozani]

Amazing Tutorial as always! the 16:00 part was very nice humor you added ;) your tutorials make us feel GN is easier than it is.

[@mtranimation]

Thank you so much! Glad you like the new way of editing I discovered :)

[@azG-rz9bd]

awesome 🎉

[@mtranimation]

Thank you! :)

[@garrysalisbury211]

Great tutorial. It could be easier on the computer if you use a grease pencil line object to render curves and edges in cycles. Works well for especially for complex curves. There is a tutorial on youtube that gives the grease pencil settings. Not as good as using a shader like yours but may do the job if rendering is slow with a mesh.

[@leonardoromero4709]

I think the reason why the velocity attribute is not working in 15:54 is because Blender already has a velocity attribute for the particle system, so outside of the geometry nodes that name is already used.

[@mtranimation]

I think so too yes. Good to know for the next video ;)

[@yves8695]

Hello MTR man how are you? Nice project you got here, cheers to that. In the midlle of the video, I had an idea, it coud work in a cube area , for exemple? Not justi in a flat surface!

[@knmbsst]

Thank you bro!! This is awesome. May I ask how did you come out with all of this information and knowledge? Do you a mathematician background or something? I'm curious bc not even by reading all the documentation I would have the logics to pull stuff like this in combination. I would love to know that. That you for sharing all of this! I'm getting your book as well

[@mtranimation]

Thank you so much! Well, my bachelor was in Mathematics. However, basically 95% of my Geometry Nodes knowledge comes from practice, practice, practice... And watching a lot of Geometry Nodes and (Python) coding tutorials :)

[@ayomideadejumo2068]

Post notification does it again ❤

[@mtranimation]

That's amazing!! :)

[@mastermill79]

Goede video, je accent is onmiskenbaar en aandoenlijk Nederlands (jaren 90 MTV Katja Schuurman, nee echt zoek het op 😂). Je nodes/wiskundige aanpak lijkt op die in Midge Sinnaeve's video's. Prachtige renders. Subbed 😊

[@mtranimation]

Dankjewel! Ik zal het eens opzoeken ;) hahah

[@torher436]

Thanks a lot, really cool! I've been trying to loop the effect but can't figure out how, looping the seeds doesn't seem to work. Anyone having an idea how to accomplish that?

[@mtranimation]

Thank you! That would indeed be a hard task since the distribute points on faces node is randomized. But you can try to use some manual technique that might work :)

[@Frigus3D-Art]

When you put the scene time through a math node set to modulo the seed numbers should circle. With the B Value of the math node you can set the interval as far as i remember Didn't test it just speaking from theory. (Mb I give it a shot today when I'm back home)

[@torher436]

@@Frigus3D-Art I tried that. Maybe I'm wrong, but unfortunately, it doesn't seem to be that simple. Even if the seeds are looped, the simulation will be in a different state. If you find a solution, please let me know.

[@weihuadong8375]

Use name "velocity" is OK with EEVEE to show the velocity color, but not working with CYCLES, changed to "velocity1" , works both on EEVEE and CYCLES

[@robertosegado3944]

how can i change the velocity to something more slow?

[@SimplyRoar]

I've been trying for days now to replicate the first scene in the video with flow fields originating in the middle and going outwards. I get that it's probably mulitple layers to get the colors, but I can't get them to originiate the middle of a place/circle and create patterns like this

[@mtranimation]

I will give you a tip: Apply the flow field on a reshaped cylinder ;)

[@SimplyRoar]

@@mtranimation Thanks for the reply but I still couldn't figure it out (: I'm considering buying your book but I'm unsure if I'm going to be able to apply it well. I really want to learn geometry nodes thorougly, but I'm fairly new to this side of Blender. I love your tutorials though!

[@michaelvaughan2986]

Could something like this be done with node material, using gn to give this sort of flow to the noise texture node in the material?

[@mtranimation]

You could perhaps try to get a similar result but without the simulation of points it would be a very hard task which would probably result in a worse looking visualization. Plus I think with Geometry Nodes there are just more and easier possibilities :)

[@synapse349]

The compare groups can be groups, can they not? I'll tweak it to be a full node group after I follow this. Thanks

[@mtranimation]

You could do that indeed :)

[@synapse349]

@@mtranimation yeah I'm still learning as they invent more and more nodes lol

[@sharukhzaman3968]

my texture is not appearing if i use velocity1 Can someone Help me Please

[@luciox2919]

that was hard

[@bUildYT]

C4D still better but damnnn they catching up fast :O

[@mtranimation]

Battle of the software! ;)

[@bUildYT]

@@mtranimation yea, congrats to 10k btw, highly deserved!

[@mtranimation]

Thank you so much! Big party overhere🎉

[@allennorth9746]

Khronos looks way better than AGX if you set yo materials for its colormanagement (saturation hue etc)

[@noobmaster998]

Nice tutorial but its hard to understand because I becomes hard to keep track of what that node is doing 😢😂

[@mtranimation]

Haha practice, practice, practice... And you will get there! :)

[@AirZeee]

Agreed, but using named frames around what a group of nodes doing has helped me. For example, increment point age, increment trail age, cull old points, cull trail end. If i didn’t do this i’d struggle to follow now, and wouldn’t be able to understand when I revisit the file in future. Hope this helps? @MTRANIMATION, nice work! Lekker Lekker!

[@orenmatar]

Hi man thank you so much for all the great content! I'm just starting to learn 3d modelling and this is really helping! I liked this tutorial so much I made my own version: kzbin.info/www/bejne/p2W5i5Vtmr-sftU

[@mtranimation]

Very cool stuff! :)

[@t1sk1jukka]

I’d suggest to remove keyboard/mouse clicking sounds out, those are annoying and then i end up watching every video without voice. Otherwise nice tut

[@mtranimation]

Thanks for the suggetion! I shall see what I can do :)

[@leafy_5]

Might be subjective, I actually like that I can hear when he’s typing/clicking cuz it helps me keep track of the steps he’s taking and when to look closer 🤷‍♂️

[@myriadrhea]

There's a limit to what you can cut out in post when it comes to mechanical setups. It's one thing if everytime the mic was triggered by talking or keyboard that we could hear a fan whirring away, but it's just clicks and they aren't even that bad. Your just asking him to change his equipment because you dislike clicking and it has no impact on how good the tutorial is. 😅

[@marshallsober]

@@mtranimation wow that is a level of critique quite epic, he cant stand the mouse clicking then run the video without the voice....my gawd. Nice tutorial change nothing but maybe a little more separation and grouping of nodes to help keep up of the use and you should definetely make a serie out of every geo node that exist beginning simple and adding and adding while the serie is advancing. a less steeep learning curve and it could be quite enjoyable

[@VisualistAyush07]

Amazing

[@mtranimation]

Thankyou! :)
