Well, I lean more towards the artistic side than the technical side, but I tried to explain a bit how to use the Position Based Dynamics from the content example because it seems mysterious to many people. I hope you will appreciate my little tutorial.

Super cool and helpful! Not much PBD content out there. Thanks for sharing your process and the result looks great!
Awesome man! Thank you so much for this! I've been searching youtube and google for pbd niagara tutorials and I couldn't find very much. This is the best explanation Ive seen for this so far. I don't know why there aren't more videos covering this topic.
Superb! Straight forward thanks you so much - was struggling getting the collisions to work correctly , thanks to you it'll work perfect now !!
Whoa, that's so cool! Finally, interactive motion graphics!
Thank you very musch! I waiting for this long time!
such an awesome tutorial. Thank you so much for sharing this!
Wow! All this content and info is pure gold! 😅
This is awesome, super fun!
This is amazing!
The best tutorial on Position based dynamics you can find right now. I noticed using it, that collision is fine with static meshes but they ignore my player, maybe because it's skeletal mesh?
This is mainly because we use Distance field for collision, and Skeletal is not in the distance field pass I think.
Thank you!
Cool stuff
Хотел бы выразить Тебе благодарность за то что Ты делаешь. Я купил эту подписку на и просто восхищаюсь твоим трудом, а постановка кадра это вообще отдельный разговор. С самыми наилучшими пожеланиями.
Thank you very much for your nice comment : )
t'es le meilleur !!!
So good. Might I ask where you got the coffee bean mesh from? Thanks
Epic my man! BTW I have tried to add 3 different meshes to the mesh renderer but it only see one. Any idea or setting?
Work fine on my side, in mesh renderer you have to clic on + (right side of the mesh to add a new mesh), after that in the initialize particle / mesh attribute tab, you need to set the "Mesh renderer Array visibility mode" on random
Amazing man, thank you so much for this. Any chance you could explain how to make the particles follow a render target using this PBD effect as a base?
You can follow this tutorial ua-cam.com/video/CrOWIqJcguM/v-deo.html or using this file from my patreon to dig in it www.patreon.com/posts/project-files-5-95330243
Very cool tutorial! Is there a way to render out the sim cache with path tracer? It works great with lumen, but as soon as I turn on path tracer all the niagara particles disappear..
Thank you : ) I don't use path tracer, so I haven't tried yet.
I understand. I have a similar issue when using ray traced shadows with lumen that my shadows disappear. I guess it's not supported? :(
Hello! Where can I find these Niagara Levels? Is it an effects pack made by you? I use version 5.2 but it doesn't appear here for me... Thank you!

Omg thanks a lot.
I have one question tho.. if the mesh is not matching the collision ( I need to simulate a tennis ball so my mesh is a sphere with some texture on it and a sphere collision) should I have to decrease the collision size in niagara? Because it's making some strange effect.. thank you again man
how i can make the Collisions smaller with mesh
Amazing tutorial! I got everything to work except for one thing. My meshes don't collide with each other. They do with the table and such, but not with each other like in your video. My mesh has no scale factor. it's all set on 1,1,1. So I figured it might be the collisionRadius or the distance mesh field. So I tried increasing those values as well, however I keep having the same issue. If you have any tips it's much appreciated.
Mmmh this is weird you have collision with ground but not between particle, I don't know : / as you say is probably the radius of collision. Keep in mind this is only a sphere radius for collision not the shape of your mesh.
I'm very novice. Can you make a tutorial on how to create the original PBD system? Would love to learn how you made the Populate grid and populate Neighbor Grid.
I just use the PBD created by Epic in the content example. I'm more visual than technical artist, so in fact I have absolutely no idea how they do the original system =D
can I know whare can I find niagara advance level?

Hello! Can you share the UE5 version that you're using.
A lot of dependencies are lost when I am trying to migrate.
I use UE5.03.
Thanks!
Hello, for this tutorial I use 5.3, but I did differents tests with 5.1, and 5.2 and everything is fine on my side. Epic add this niagara exemple in 4.26 so theoretically all following versions should be good.
Unfortunately is not the case as of today in 5.03. When you open the content examples project you get a message that the Initialize particle module is softly deprecated and will be fully deprecated. If you replace it with a Niagara module a whole bunch of dependencies start to fall apart. @@sumours
Sorry, I want to follow the tutorial but when I start I already encounter my first obstacle, where do you get the particle system that you start with? Is it something active payment?
completly free :) www.unrealengine.com/marketplace/en-US/product/content-examples
@@sumours Thanks!
Hello! ? need your help! The particles don't touch the surface or floor very well, it seems like a collision error. How can i solve it? Thank you!
Upscale the resolution of your distance field mesh as explain in the video or Another thing I don't explain is your mesh should have a uniform scale don't deform him to keep a good distance field pass.
@@sumours Sorry, I scaled the object using 0.04 but I have problems with the collision on the floor. If i put bigger scale like 0,2 the collision it's ok. The problem is that my object now is out of scale. How can I resolve this? Thank you very much!
@@beatricedibiagio5236 try to >> scale your mesh as you need and export your mesh in FBX, reimport your new mesh and that should work (distance field don't like scaling all your should be at scale 1, 1, 1)
used the same 3d model but lags horribly when bumped the particle to 1500
Everytime I use a 3D model as particle I drastically reduce the number of polygons in blender
@@sumours can you tell me how much you reduce it for example?
@@terabaap2104 there no specific number, if the model still look good I reduce much as I can : )
@@sumours one last question my all partricle stay flat on wood they dont stack , please help?
Them accents are wild 💀
Good Job! can it be simulated with skeleton mesh animation?
I did not try, but I've seen few examples that do it like this one vimeo.com/425280683
thanks~@@sumours
