For anyone following this tutorial, if you can't see the "Activate Cloth Paint" button at the top of your skeletal mesh window, make sure to head on over to the top window bar for your project, click edit, editor preferences, then with after clicking "all settings", search for "cloth", then at the top of the list, click enable clothing tools, and then restart unreal engine.
hi man ive done what you said about "turn on cloth tool and restart" well i did that and it still wont show
@@Frizzler go to window > Cloth paint and enable cloth paint. :)
i searched for "cloth" and got 0 results. (this was while using Conan Exiles Devkit).
Ok , great Video , but nothing works on engine version 4.24 , the simulation doesn't do anything and the wind doesn't blow anything.
-----> Here is the fix for that version :
CLOTH SIM : you have to APPLY DATA only AFTER you have painted the mask( the pink and white painting thing)
THE WIND : you have to input a NEGATIVE value in the strenght slider
Dont't ask my why they are only workaround the bugs of the engine version.
5:14 hello guys, sorry to interrupt with such a non-sense question from me. At the time I mention, when I finish painting weight and click "Deactivate Cloth Painting"; mesh doesn't affect gravity in the video game at all. It still stands there at the same original post I import as .fbx
Do I miss something or do I need to activate anything before it will activate
Thank you guys
Yeah, same problem
same problem
Please see my above post. I had the same problem and wasted a day trying to get cloth simulation to work and then found this workaround on the Unreal community site: forums.unrealengine.com/development-discussion/content-creation/1724703-4-24-i-can-t-get-cloth-physics-to-do-anything-at-all-need-someone-to-tell-me-what-i-m-missing
Pleae redo this tutorial for 4.24. After following your instructions EXACTLY, the flag will still not work (stays static).
Same problem for me. In fact if I create it in 4.23 and then upgrade to 4.24 it still works, but when I do exactly the same steps building in 4.24 from scratch it doesn't work. Anyone have a resolution for this yet please?
I found the following on the Unreal community site, which seems to work. Not very satisfactory but at least there appears to be a workaround. forums.unrealengine.com/development-discussion/content-creation/1724703-4-24-i-can-t-get-cloth-physics-to-do-anything-at-all-need-someone-to-tell-me-what-i-m-missing
The Wind don't affect the clothing simulation, I did everything same as you :(
Doesn't work for me, after painting the cloth and exiting paint mode, exactly as in the video, nothing happens, no simulation and the flag stays still
same for me. doesn't work.
@@jeffreywarf4568 I found a solution where on the Mesh section (where the others are skeleton and Physics section), beside the clothing tab for cloth brush, there is the skeleton tab, right click the Flag_Pole bone and go to remove selected then select From LOD 0 only. Hope this helps.
The way works on 4.23. But when I do the same thing on latest 4.24.2, it does not work.
@@kenshin2430 This worked for me and I'm using 4.24
if you cant start the simulation, try to press reimport mesh button
awesome..thank you so much, its sooooo dam cool the amount of realism this kind of stuff adds. holy freakin crapsacs i love game development(most of the time :P) have a fantastic day!!!!
For anyone having problems with this in 4.24: AFTER painting you need to select your section and click "Apply Clothing Data" again
And 4.24 - you need to TYPE the brush value. The slider only goes up to 100. Spent whole night trying to figure out what was wrong. My cloth was just falling up to a point, hitting an invisible plane afterwards.
when i use the wind directional source nothing happens..any ideas? :S
Hi, I have problem. I've done everything correct till 5:11 and then my Flag didnt fall just stayed as it is...
How to solve this?

04:07 is the actual simulation, lovely tutorial btw!
What about hair ? Almost Characters need hair , but look like not even the Unreal market sale hair for our female characters...
Hi everyone, for those with 4.24, hit "Apply clothing data" only after you paint, otherwise it won't work.
Yes, delete all and apply only after the paint
Looks amazing. I've never done anything associated with cloth before and will probably try this out one day.
The results looks amazing and of course I understand the simpler it is and the less time you spend the "cheaper" results you get (even though it looks amazing already), but using your video as a reference - is there a way to give the flag an ever smoother animation? the cloth meets itself beautifully in the animation, but everything "outside" or around the flag or whatever you wanna call it, sort of stutters in the animation. Is there a way to make it stutter less and give the flag overall a much smoother animation?
Hi, thanks :) Definitely give it a go yourself, it's super easy. As for the 'stuttering', this can be fixed just by tweaking the wind settings. Maybe by setting the strength lower and putting the speed up, the motion will smooth out. I'll do a bit more testing and have a look into it, thanks again!
Thank you :)
It's gonna be exciting to play around with this some day :)
how do you do when you have a complex mesh with alot of different parts that has a cloth onto it?
I cant seem to make it work in 4.24.2... :/ I looked into my physich asset capsules and it wont even react to those, my cape just stands there straight :/
Having the same issue, a quite baffling thing I noticed is that if you light up the flag with a spot light for example, you will see that the shadows of the flag will appear as if the flag is moving in the wind, but the actual flag is standing still - this is some next level quantum stuff seemingly happening right here
Hello. I am using 3ds Max, and when you attach "flag_flag" to "flag_ pole" i don't know what function that is in 3ds Max. Could anyone help with this?
2018 he is using winamp ? wtf
Best PC mp3 player ever made! ;)
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,
Will it interact with your character if you collide with it? Or only with wind and movement?
If I want to record that to sequencer how do I do that? thank you.
works great! thank you. how can you make two independent constrain points so you can like stretch and move the cloth?
Beautiful, thanks for the tutorial. Can you add thickness to the cloth?
I want to make a flag that flutters in the flag, breaks off, comes off from the flag, flutters in the wind, and lands on a rock. How can i do that?
Awesome quick little tutorial. Thank you. Used concept for a hanging banner in my 4.23 sci-fi project with no problems. Also, tested in 4.24 with no issues.
Nice tutorial! But It doesn't work in UE4.24?
It's tested and working in 4.24 :)
@@underscore00 After testing, it can't be implemented in 4.24 version, it can be implemented in 4.18, I don't know if there is a bug in 4.24
@@qianyingqiu8310 I've tested it myself in a fresh project using the tutorial assets in 4.24 and it's worked exactly as it does in the video. I'm not sure why people are having issues with 4.24, but I can assure you, I've tested it myself and it works fine :)
What if I wanted part of a game character to be affected by cloth physics? Like a character wearing a robe or a loin cloth, or long hanging hair, that sort of thing?
You can do that in the exact same way as described in the video - as long as the robe or cloak is included in the physics asset of the character, it should work just fine :)
Excellent quick breakdown video tutorial. New sub coming in hot.
perfect .. thanks for your time
Thats cool thumbs up man thanks buddy worked for me well done :)
great tutorial
but i want to ask you how to make the wind strength and speed random ? , so the flag fly and stop randomly
Definitely possible! In fact, I'll make a video about it very soon :)
thank you very much
I seem to be having a really strange problem with creating my asset and importing it into unreal. I used blender to create a cylinder with a plane next to it, subdivided the plane, triangulated the mesh, parented the plane to the cylinder, then exported it as an fbx file.
It imports into unreal just fine, and I can apply the cloth as well. The simulation runs and the cloth deforms just how I expect it to, but when I do so it tells me that there are 0 simulated vertices in the clothing data and the wind doesn't affect the material whatsoever. I've been trying to figure out where I went wrong for hours. Any ideas?
Note: When I use the fbx file in the video description everything works perfectly, but I want to be able to create my own assets for this as well. I've also tried creating the mesh in 3DS Max to no avail.
well blender is garbage but I forgive you because you used 3dsmax :D There was an issue I encountered where geometry wouldn't behave properly in UE4 exported from 3dsmax. Basically, if the object is not set as "editable mesh" and then exported as a .fbx you'll have issues.
Awesome thanks, what about if you wanted to anchor the cloth in more than one place? How would that work?
Thanks for the flag
wow....It helped me a lot. Thank you.
This is great! In 3D max would it be a straight forward group or would you need to link objects?
collision with actors or only wind ?
Wind only by default, though there's probably a method for getting it to collide with actors
There should probably be a button somewhere somewhen that will make it interact with other actors.
can i use this for hair?
Section Selection Selected, Section Selection Selected, Section Selection Selected :)
XD
Ohhhhh snap! That's freakin awesome! I needed a flag and a parachute for one of my projects but ended up creating an animation for it because I couldn't figure out how to go about it. I never realized I could do that in UE4, that is truly fantastic and a huge time saver, thank you so much!!
Let me guess battle royal?
can you add weight to the flag
Window 7. Iam so proud
this is the right way for 4.24
1. right click, create clothing data
2. activate cloth paint
3. start brushing
4. deactivate clothing paint
5. right click, apply clothing data
it works for me
Totally AWESOME:(. Thanks😁
Nice tutorial thank you!
I have a question. How to make cloth simulation for game? Too high polycount (lots of subdivisions) would be to expensive for games? So what is the compromise to make nice looking cloth simulation while keeping performance good?
Hi man, thanks for your tutorial. It is really helpful. I use Maya and UE4 too. Now I need to more detail setup for clothing for game charcter in UE4. Could you please recommend some other tuto for it?
How can you go to modes?
It is great but sadly does not work on any clothes like jeans or shirts after I did what you did there is no option for Apply clothing data
Hi, thanks for the comment :) this is an old video now, check my channel page for a remake of this tutorial in a later version of the engine.
@@underscore00 retried with new video what is happing one I create clothing data it look like it work but when I re click to apply clothing data its all grayed out?
@@underscore00 I got it to work but not sure it its right when it son does not look like jacket any more it just cloth and looks really weird like a flag hanging down and when I am playing in the editor its q got ng cloth should there be a way to as tach to third person first then do it ?
Hey Underscore, theoretically speaking is there anyway to get my Grass to follow the same direction of the flag? AKA to respond to the directional wind actor. Ue4 seems to want to make wind difficult.
How do you create an object like the flag where you could select the pole and the flag individually in UE4? Thanks
@04:28 was killing me, did not notice that i should APPLY it after i just created it...thats some BAD usx here :D
Thanks for the tutorial, man! Seem to be having the same issue a number of other folks are running into though, the flag is sagging and showing proper physics from the cloth painting, but the wind directional source is having no effect on the skeleton in game test. Cloth sags, but no gusts or billows. Is this no longer possible on recent versions of UE4? 4.24, 4.25, etc?
I have look everywhere, but anyway, Do you have any idea if it is posible to interact a mesh with cloth, with a movable object, example the 3rd Person Character UE4 has? or your own pawn
How do you assign collision objects?
It works great, but when I do it again for a second asset it doesn't work. any ideas? When importing I cleared the physics asset so it creates a new one and not use the one from the first asset.
Really helpful little vid to jog the memory - thank you
all was ok for me.. until i try to add the WindDirectionnalSource... it does nothing
me too..have you found a solution yet? im trying to find one :)
@@NatesPlayzGamez it's ok now. i don't know really what was the problem. i've recreate a new scene, and put the wind in.
Hi do you know of anyway in UE4 to make it so you can shoot hole in the cloth/flag?
my cloth paint settings aren't showing and i can't find them. can anyone help?
Are this more optimize than the traditional vertex painting with world position?
is it possible to use THIS for make a soft body.... car? (deform mesh)
brilliant!
in maya when you parent, you combine the two objects?
thanx thanx
I used this tool and got weird effect on my mesh its leather leggings body armor and when the character moves it vibrates..
good job,but i have one question about it,i follow this tutorial,and everthing is gonne be ok,but in game,my flag move for seconds and stop,u can solve this problem?
is there any way we can have the flag collide with a wall behind it?
nice
Where can I get the directional wind system? I couldn't find it in my Starter Content. Otherwise Great Tutorial!
Great easy tutorial! Need some help though. There's a point while painting that if I pass it the simulation glitches out and the cloth of the flag stops showing in the game world. I can't even paint it next to the actual post cause this happens. Anyone else experiencing this or know how to solve it?
Thanks
Hi great tutorial! I followed every step (i'm making a torri with a banner going across it) and when i get to the physic part; i've realised it's not linked to my mesh at all; just brings me to a different screen entirely
instead of skeleton>mesh>physics i have skeleton>mesh>animation
Hi, thanks! Sounds like you're looking at the physics assets and not the skeletal mesh. If that's not the case, try deleting and re-importing the asset. Let me know if that doesn't work and if you can, send me a screenshot of what you're looking at and I might be able to help further :)
Youre welcome; and i meant at 3.15 of your video, top right you can see the hierarchy skeleton>mesh>phsyics. Mine doesn't say physics but it says animation. I have the physicsasset but its not part of the heriarchy :)
That's interesting... I've got the engine open now and I get skeleton>mesh>physics when I open up all three files; the links at the top right of the screen just switch between which asset component you're handling. If you're seeing 'animation' then my guess is you've imported the skeletal mesh with animations? When I open up UE4_Mannequin_Skeleton (the default third person model) I see skeleton>mesh>animation>blueprint>physics, which is closer to what you're seeing. Either way you should be able to create the cloth simulation as long as you have a skeletal mesh asset.
So to sum up, things to consider are importing the asset without animation (and without it automatically creating it's own animation blueprint), making sure it's being imported as a skeletal mesh, and making sure your cloth mesh is grouped to the rest of the asset or rigged to the skeleton you're using. I hope this helps! If you're still running into trouble, let me know. I might need to see it myself to offer anything more specific.
edit: Oh another thing it could be is your engine version. I made this tute in 4.19, and (don't quote me on this) the new built-in cloth tech was introduced in 4.16 (I think).
Thanks for breaking it down, you're super helpful!; unfortunately i think it's my version number, i'm only on 4.15 because that's what my uni has (cries), but i have 4.18 installed, i'll give that a go after lunch and get back to you on that one, I thought I was going mad haha
:)
nice, thank you!
How do you then apply this to the sequencer? Everything I try keeps breaking! *Very cool tut by the way :) Thanks
Hmm seems it renders animated, it just doesnt play back in the sequencer :/
skelittle mesh?
Is there a way to bake the simulation for this?
That's called an animation.
thank you....amazing tutorial and great thing that you get to have the asset download too if youre in a hurry...respect and love!
Pretty informative, but mines doesn't include physics for some reason.
Import as skeletal Mesh
is there any way to make a cloth type of material to be overlayed over an object, and but to have transparency?
The simplest way to make the flag interact with other objects is to add those objects to the cloth physics asset. I havent tried doing cloth with transparency, but it should work fine! Hope that helps! :)
will this work with hair too?
It should work for hair, yes. Though you probably have to tweak some values here and there to make it work.
@@PaladinfffLeeroy thank you having trouble with a pony tail.
Thanks very much!
awesome..thank you so much!
But what if the character and cloth are directly connected to each other?
Or if the character you made is in Blender?
It shouldnt be a problem if you use blender - as long as the object hierarchy is the same and you can import the asset as a skeletal mesh, it should work fine. If the objects are directly connected it should work OK as well :) Give it a go! Let me know if you run into problems :)
Hi, is this method work with hair?
"Oh yeah anything, clothing actually *chuckle* It's the prime usage for this kinda thing" I don't know why but that was hilarious lmao.
i have a problem when i did all you say, the flag turn around the mast
Could just be a problem with wind direction. Try and rotate the flag or the wind direction component and see if that helps.
when i brought my fbx flag in, i cannot seem to select the cloth separate from the pole? I created it the exact same way as you did in maya.
Are u sure u applied different materials to both?
Thats fantastic! Thanks.
Hey...so I tried this and when I got to the point where I'm painting (about the 5 minute mark), I don't get the paint circle you get. I get like a green line and all the lines on the flag are green. What am I doing wrong?
I'll have to double check this - there's been 3 point releases to the engine since I made this video so it could just be that the in-engine graphic has changed. So nothing happens when you try to paint?
I'll have another look at this and get back to you :)
@@underscore00 Thank you so much for answering so quickly. I know Maya somewhat well so I totally understand the process (making a waving flag was one of the first things I learned in Maya). Thanks again.
How do I get a value
how did you get the flag to not go through the mesh?
The cloth will interact with anything in it's own physics assets.
Thank you for this tutorial man
Thanks for the tutorial!
An issue I'm having is that when my flag deforms it doesn't do so smoothly. As in, I can see the faces in the mesh of the flag where it deforms. I have tried it with another plane as well and still get the blocky deformations.
Sounds like a mesh density issue. Add more subdivisions to your mesh to give the cloth more faces to deform. Thanks for watching! :)
thanks a lot
Great tutorial thanks!
For 4.24 After finish painting, unselect "Deactive Cloth Paint" first!! then right click and "Apply Clothing Data"
hey, for some reason using the wind directional souce doesnt affect my flag..any ideas buddy?
@@NatesPlayzGamez how i can earase some Areas ? i clicked shif,alt ,ctrl...nothing happend ?!please help
@@blackswan6386 hey bud, i dont know of the top of my head,im going to bed soon but i can check tomorrow and let ya know if you want? :)
@@NatesPlayzGamez i solved this, you can erase when you make the " Value" to 0 :D - sorry for that i was searching an icon or some rubber item. its solved, thank you bud
@@blackswan6386 ahh ok cool, good to know! stay safe brother :)
Cool bro!
Does it have colliders? Like, does it react when the player walks into the flag? Great video!
Thanks! :)
The cloth will collide with anything inside it's own physics asset, so it will react to the pole, but not with the player. I might revisit this sometime to show how to tweak it to react with the world.
Yeah, that would be really great! Thanks for the video ;)
@@underscore00 Did you ever revisit this to tweak it? This is the first question I had after watching your video (which I appreciate you creating by the way).
Got a new subscriber... thank you!
You're welcome :) Thanks for watching!
How do you erase certain areas once you have painted over them?
adjust the paint value
but that's distance in cm so you need to make sure your scale is correct
or, shift+left mouse button. sorry, i'm finding these out as i go along too
thank you thank you.
