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.

Super cool and helpful! Not much PBD content out there. Thanks for sharing your process and the result looks great!

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?

@sumours 10 ай бұрын

This is mainly because we use Distance field for collision, and Skeletal is not in the distance field pass I think.

Superb! Straight forward thanks you so much - was struggling getting the collisions to work correctly , thanks to you it'll work perfect now !!

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!

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.

@sumours 8 ай бұрын

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.

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?

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.

@sumours 9 ай бұрын

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

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..

@sumours 11 ай бұрын

Thank you : ) I don't use path tracer, so I haven't tried yet.

@lummi_vfx 11 ай бұрын

I understand. I have a similar issue when using ray traced shadows with lumen that my shadows disappear. I guess it's not supported? :(

@citamus 6 ай бұрын

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

@metatrox 11 ай бұрын

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?

@sumours 11 ай бұрын

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

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!

@sumours 11 ай бұрын

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.

@eraniopetruska5701 11 ай бұрын

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

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 thanks for this awesome tutorial. i've also got a similar issue. I've checked the static mesh of my coffee bean and the collision mesh is accurate to the bean, but I can see from the way the bean rolls in the simulation that it's rolling like the collision mesh is a sphere. Are there any settings within Niagara that would cause it to use a sphere collision mesh over the one in the static mesh?

@@keithlynch9846 Unfortunately this process only work with a sphere collision, you cant use a custom collider. I asking Epic for more possibilities in the futur.
