How To Create And Use Cloth Simulation In Unreal Engine 5 (Tutorial) | Flag Physics With Wind In UE5

[@Greenman4890]

That's surprisingly simple to implement, cool

[@MartKart8]

That's so bizarre I have a flag with the union jack as well in Unreal Engine, the flag works and blows in the wind, when using the Wind Directional source. Yes, I'm British as well

[@MattAspland]

Oh wow that’s great! :)

[@CharlyGuisante]

Clear, easy to follow and perfectly explained. Thanks mate!

[@nicodela6854]

It can't create a physical asset : The bone size is too small to create Physics Asset 'Foodstand_Flag_PhysicsAsset' from Skeletal Mesh 'Foodstand_Flag'. You will have to create physics asset manually. I guess it has something to do with blender export. but I don't understand how to solve this. So it does work with the wind, but I can't interat with it.

[@DenisZaharenko]

Is it possible to setup thet the wind automatically gets less and more after a while? Like real wind. So sometimes the flag is just hanging.

[@coystt7233]

Can you animate the wind force?

[@eobet]

When I follow this tutorial and import the FBX from Blender, I get an error saying "bone size is too small to create physics asset". But I don't see you creating any bones? The weird thing is that my flag is over 1m in size and I get the same error message even when I try to create the physics asset manually.

[@lasciviousembrace]

Same

[@lasciviousembrace]

yo make the flag absolutely huge and it worked for me

[@faheemmushtaq3514]

how i can simulate a flag without pressing the play button, is there a way to simulate a flag in the viewport?

[@GPT-City]

What does your physics asset look like because mines not working properly

[@SiLiDNB]

Thanks, this is exactly what I was looking for.

[@paulbeeley6210]

Great tutorial thanks! I had issues importing it and it creating a Physics asset. Worked out that you cant use image as planes in blender.

[@IsaacCode95]

Great Tutorial ! i really learn alot from your videos matt cheers ! Is there a way to mey it work with the weather system that has just released free for the month ? Any tip would be great !

[@jamesonvparker]

Hi @Matt Aspland, is it possible to make the wind always point towards a certain actor in the scene? Like if I had a black hole that moved around in the scene and I wanted the wind to always go towards it?

[@MattAspland]

Hey, great idea! You could do something similar to this video. This covers how to make something always face something else. You can use the wind direction to the black hole. kzbin.info/www/bejne/gJzZpKqojd51maM

[@jamesonvparker]

@@MattAspland awesome. Thank you so much! Can’t wait to try this!

[@jamesonvparker]

@@MattAspland this definitely helps. I just need to check on having multiple wind elements in the scene with an area of effect so that the wind on the opposite side of the black hole would still point towards it.

[@MattAspland]

If you want them all to point toward the same black hole, I believe this should still work for you

[@kevCarrico]

great video - thank you! 🫡🇬🇧 i had the same issue with 100 not being high enough for the Paint Value - and causing glitches - but that was fixed when i set both the Brush Strength and Falloff to 1.

i have a problem please help, if we render this animation out with AA or Sub surface samples more than 8 it start going crazy fast, please please guide,

[@Blacksuitor]

Hi, I have created exactly what you do. It works well in simulation, but when I export it, the flag moves 100 times faster. How could I solve this issue? It works normally before export, but the result is totally different after export. It's been a week, but I could not figure out what went wrong.

[@dkfox9737]

muito top ajudou muito, simples e prático 👏

[@monteeldas]

Thank you.

[@somerandomindiegamedeveloper]

Very well :D

[@travisbehrendsen6992]

okay, so how do you unpaint a painted area? obsviously CTRL Z but.... i messed up

[@dubblesnup4457]

instead of painting with the "Paint Value" to 1000, set that to 0.

[@SLAPMYGORILLA]

My physics assets are always capsules, and changing it to a cube does not help.

[@Rogueixpresents]

whats the impact on the GPU for these cloth physics?

[@Greenman4890]

I'd avoid it when you don't need it, you can get cheaper performance with either animations *or* what I like for some wavy cloth effects is using the simplegrassshader node and apply that in your material instead. Cheaper. Personally i'd use cloth physics mainly for objects that need high detail, like characters for example with a cape or something.

[@althedude7730]

im sorry i was genuinely looking for a video like this, but lost my shit at the Queen Elisabeth half mast thing... Am i a bad person?

[@Lars_Ekstrom]

Nothing happens for me when i deactivate cloth paint, mesh doesnt move at all:S

[@seanposkea]

Great as always, Matt. Question, is there a way to have collision? When there was no wind your flags just fell through your pole. But I could see a million uses if this was able to drape over things and not pass through.

[@MattAspland]

Great point! This somehow slipped my mind when creating this video as I didn't really notice it. The below link should hopefully help out and explains it pretty well with pictures. I can look into making another video where we add collision however if you think it would help. dev.epicgames.com/community/learning/tutorials/p4a1/unreal-engine-cloth-collision-with-world

[@GTAIV327]

For da queeen

[@rathore3991]

Can we bind it like we have 2 flag but wind direction should affect only one and for second flag we can use another wind direction with less speed or strength!

[@crackedeggstudios]

Just a note that your cloth must be exactly 1 vertex deep along one axis (so your material must be 2-sided). If the cloth is more than perfectly flat (2 or more vertices), it will inflate like a balloon, rather than sag/flap.

[@emptybruh]

So it has to be extruded in 3d program to have some sort of depth and not just a flat plane?

[@unrealdevop]

I believe you can control that with the pressure settings. I would have to test it to see.

[@routeone4790]

how do i fix this as mine is going like a balloon?

[@kevinoconnor7001]

If anyone is still having an issue with ballooning of their mesh, double click the physics asset and move the collision capsule until the mesh behaves the way you want it.

[@LawsOnJoystick]

bro.. this was the comment of the year,Thank you so much :)@@kevinoconnor7001

[@warfighter4129]

Hey Matt i`m using this clothing system for my Character`s hair in my game. But it clips through the body, maybe you could make a video on doing basic hair physics using cloth simulation!

[@MattAspland]

Great idea!

[@rob_meade]

Hey Matt, quick question, how would you add some "weight" to the material? For example, whether that was a flag, or a cape, or anything, its very floaty, is there a way to dampen that down so that it doesn't bounce/flap around so much? Also, collision? I noticed your flags wrapped around themselves/went through themselves, is there a way to prevent that? thanks in advance :)

[@kevCarrico]

the free Content Examples project in the Samples section of the marketplace has a map for cloth, and in there you can see the different setting for things like silk, rubber and burlap.

[@jbbird3548]

I love this channel, haven't watched enough of your content! Have you made a video on general soft body/flex body physics? Like how you'd simulate rope laying on the ground etc. I've been digging and haven't found a good UE5 video on it yet

[@rifat.ahammed]

How many tutorial must a man walk down Before you call him an UNREAL man ? The answer, my friend, is blowin' in the wind The answer is blowin' in the wind...........🎵🎵🎵

Thanks for posting this, it was very helpful. How do you record the wind movement in Sequencer? It seems to only work in game mode but when I render the wind doesn't work.

[@MegaEthee]

Yeah, I've been having this same question too. A tutorial on this would be great!

[@chetosaakula1226]

hi, did you find a solution?) now I have this problem

[@chickishot8172]

RIP Queen Elizabeth II. Also great tutorial, I’ve been wanting this type of tutorial for awhile. I would love to know how to implement this on a player’s clothing or hair.

[@MattAspland]

RIP And that's great to hear man. Also, this should work the exact same way for player's clothing, however hair has it's own physics that you can use instead. I'll link the docs for it below :) docs.unrealengine.com/5.0/en-US/hair-physics-in-unreal-engine---overview/

[@chickishot8172]

@@MattAspland Thank you very much! I figured it would be a similar method for clothing attached to the character, but I wasn’t sure because things to me for UE usually seem much simpler in theory than in practice. I will definitely be using the link you sent.

thanks for the video. how would i render this so the flags move when rendering a video?

[@kevdillon7223]

This is good but how do you get it to work using Sequencer i tried adding physics in Sequencer and still no movement can you do a video on cloth in Sequencer please

[@_jeffrey_williams]

cloth works for me when using a camera cut track in sequencer

[@maddened3746]

when i used this on my character's cloth, it inflated as if there was a baloon there lol...... what's with that ?

[@kevCarrico]

the cloth needs to be one vertex thick... a single poly that's subdivided... then the material is set to "two sided."

[@ronelm]

Every time I activate cloth paint the mesh disappears, anyone else?

I don't have the "clothing" option in my window menu. Am I missing something? Edit: Got it, I'm on the skeleton and not on the skeletal mesh. There are two buttons on the top right, with a drawing of a skeleton and another one next to it. The right one should be selected.

[@alltradesjack6594]

Hello everyone, I'm having a problem in one of the steps of this workflow. See, when I press "activate cloth paint", my mesh turns completely invisible and non-interactive ... if I press "h" I can see it again, but only as long as I keep the key pressed and I cannot do anything else with it... My version of the engine is 5.0.3, and weirdly enough, in 5.1 it seems to work properly. Does anyone have any clue on why this could be happening?

[@forrestarnold666]

Thank you for the awesome video Matt. I noticed that both your flags are moving in sync with each other. Do you know of an easy way to offset the wind or cloth solver so they move randomly and not the same? I've got a line of flags all flapping and moving in the exact same way. Not very realistic.

[@aryyadey2700]

Hi. I want a solution for my problem. I have a character with pose static mesh import from maya. character had a cape cloth. I export it individual and enable skeletal mesh option.

following this tute, when I right click and 'create clothing data from selection' and then 'create' it does not appear in the clothing window. I'm working on a dress with a hood. There are no bones in it - just an export from marvelous designer.

[@howtostartaclothingbrandd]

did you figure it out

[@ScottBarrettihq]

@@howtostartaclothingbrandd well, yes and sadly, also no. If I cut away the hood part of the dress then it allowed the cloth painting. However when I attempt to simulate it immediately balloons out into a capsule shape surrounding her. It might be because it’s 100x too big when I add it to the metahuman. I have to scale it to .01 size. So, still experimenting

[@howtostartaclothingbrandd]

@@ScottBarrettihq i figure out how to do it , when you are in the skelital mesh you just hover over the object and right click and it will pop up to make it cloth
