For those which characters stop animating after a while and are only flying I found out that you need to open ABP_Crowd animgraph and set MTN_N_WALK_F to loop in the settings. It still not works perfect, but it loops the animation so it never stops.
Unfortunately, it doesn't work with 5.3 . I tried anything, even the Traits corrections suggested, but I obtain just some persons that walk in place. ah and there is in any version a strange bug, like a glitch with the shadow that intersect with the main skin. Someone have a solution? thanks.

While I'm here, let me give some input that might hel someone that runs into the same problem as me. If you're importing some meshes for landscape, they might come with no collisions. If that's the case, when you hit play, your crowd will fall into the infinity and you'll be just seeing the ai debug, should it be turned on. If that happens, try to build the collisions for your ground mesh.
I wish the tutorial would explain why we are doing everything. Some of it was obvious, but some brief descriptions would be really helpful for learning.
I recommend following the official Unreal "Your First 60 Minutes with Mass" tutorial in addition. They explain a few details and if you did that one first, and then do this youtube tutorial you'll understand what is going on a lot better.

First of all - Many Thanks for a wonderful tutorial ! Really Really appreciate your work ! As I belive many with me would like you to do an updated version for 5.2 because I don´t believe there are one person here that use 5.2 that has it working....I got 60 Errors when compiling - And that is just to much to be resolved....Like many others here there are problems with Mustache, Beard and Hair but also "Set Grooms Material". I tried what people have suggested here - but no luck. So please please - Could you make a New tutorilar for 5.2 - Because of Nanites nearly everyone will use 5.2 soon i guess.... IF someone here has a working version - An example of the Mass Crowd working (Not the city sample...) it would be much appreciated to be able to download or in some way understand how you got it working.... Kind Regards
Same here got rid of all warnings, but when it comes to simulate, nothing happens got an error, cant recall what it said as i deleted , but it was to do with missing fragments on the stat tree, but i couldn't figure it out
Hii, thanks for the tutorial! It´s almost working in 5.1, but I think the walking animation isn´t looping. I guess it´s because I can´t find where to put the things of the 5.1 screenshots : ABP_Crowd-SeguencerPlayer-Details Where can I find that panel? Thanks!!!!
Hey, Thank for the tutorial, I am facing an issue that i can't find a fix for, following ur method on 5.2 worked like a charm but this doesn't work on 5.3 it just keep crashing once i open the BP_CrowdCharacter ( causing a rash with Rigvm and multiple other things) IDK what to do to get it to work on 5.3
@@arshankhan6833 Some suggested I follow this video instead to get the animations into a tape recorder. Going to try today. th-cam.com/video/9MLjstChfDM/w-d-xo.html
Thanks for the tutorial. It all went well, but at 9:20 I couldn't select the state tree that I made, somehow the Mass Entity Config doesn't see my state tree. Any help is appreciated. Thanks!
It is only needed for the Danger Annotation and we don't use that atm.. combined with the MassAI traffic, traffic can add a Danger Annotation to a Zone and Pedestrians will avoid that zone. Later on I will look at making my own annotations, but ZoneGraphAnnotation only comes with the Danger annotation build in..
@@viperdkue5 Ahh gotcha, thanks. Any idea what would cause the peds to keep moving in their initial direction, but the mesh rotates in the direction the mass agent is moving in? When the ped comes to a corner, the mass agent debug panel moves along the path, and the mesh does rotate towards the new lane orientation, but keeps moving in the direction it was going. This makes it look as if the ped is walking sideways. Almost as if the velocity is not being synchronized from the Mass Entity to the actual ped. The three traits are setup identical as in the video (Capsule Collision Sync: No Sync Transform + Actor to Mass) / Movement & Orientation Sync: Mass to Actor.
@@viperdkue5 Tried that, but didn't make a difference. Did some more digging and found out that the Character is in a falling state, causing the velocity that it receives to not be applied as we wanted (can't move forward if you're not touching the ground). So when I find out why it's not touching/detecting the ground, this will most likely be resolved.
Okay, the sounds weird.. maybe try and change the capsule collision to sync transform, if you use the AIDebug and press shift G and select a character, you can see where the capsule collision is.
Big thanks!! I'm trying to make a little cyberpunk street. What do you think is the best practice to make use of this and change pedestrians to cyberpunk look?
Great tutorial! It works for newbie like me! But is there any way to make the crowd not collide with each other? The original crowd from ue5 City sample have a sensor which make them not colliding with each other
Not really, because MassAI limits the amount of high res actors that is visible on the screen and use low res actors at a distance and we can use a static mesh with vertex animation material at far distance. off screen there is no actor, just the MassAI agent that is highly optimized.. In the City sample project they use thousands of characters, so it works at scale, if you setup it right..
@@SonicTheCat When BP_CrowdCharacter is used as low res it Ticks at a lower rate, if you add a SimulationLOD Trait and enable Variable Ticking and this is just a quick getting started guide, its the same way EPIC does it in the Matrix demo, but yeah it can be optimized a lot more, I think its one of the main reasons the Matrix demo runs at so low FPS..
@@viperdkue5 This part shocked me too. I think you should also talk about the optimisation process because nobody wants max res metahumans being rendered when they don't need to be
I followed every step correctly, even had to rewatch to check Mistakes, but when I run the simulation, it says some fragments are missing and idk which ones are
I just did a test on 5.1 and it seems you need to enable Groom plugin manually then City Sample Crowd works normally. I'm still testing MassAI in 5.1 but think we just need to remove some traits/fragments and add other traits/fragments and it works like in 5.0.
thanks for this! working great. However.... holy shit, i wish it was a bit easier. If it wasn´t for this tutorial i wouldn´t have a clue how to get it working.
Thank for your tutorials, it works fine on 5.1. Just wondering how we can assign another animation/behavior of these characters, not just walking only.
I tried to solve the traits problem, following the link..but I can't find in the "CrowdAgent" editor the traits = Transform Fragments and Agent Radius Fragments". So the result is always the same, when I do Play nothing happens and it keeps reporting the Traits problem. I use EU 5.2
@@genieeye5783 Unfortunately it doesn't work, when I do Play no character appears and the message "some fragments are added by multiple traits and can only be added by one" appears.
Hi I am new to unreal engine. and i wonder how can we add these crowd in level sequence and make a cinematic camera and render it. becauez the crowd only emits when we hit play button. what if we are making a short film and have to add crowd in a shot. how can we do it? Can't we emit crowd without hitting play button and add them in level sequencer so that we can render them. please reply if you can i am stuck in there, i don't know how to do it. thanks.
@@dan2059 I got the solution. simulation will automatically trigger when we render it. we can't see it in the camera view while scrubbing in level sequencer but it will be shown in the final render.
@@abhishekbasiwal3thank you! So if we can’t scrub through it, then there would be no way to animate a car weaving through traffic without doing it in PIE, right?
@@jobegruen4273 Yes, Crowd will emit in final render only. Or maybe there is other workaround with blueprint but i have no idea about that as i am not that good in blueprints.
Hi, thanks for this helpful tutorial. May I ask what can I do to assign another animation/behavior of other characters, not just walking behavior? I tried making a duplicate of the ABP_Crowd and change the animation but somehow it doesn't work. Thanks in advance for your reply.
Hi. Amazing video, by the way. Is there a way to activate the crowd mass ai when doing a movie in sequencer? I tried to track pretty much everything I thought that might work, but I had no luck with that. Can you help with that, or does anyone know something about this?
@@viperdkue5 I think there might be a way to trigger an event in sequencer that activates other events on a blueprint. The thing is the crowd mass is working based on event begin play. I'm trying to do that in sequencer. If you have a BP_character, you can track it on sequencer. When they spawn on event begin play, you don't have them on the outliner
@@ruimarques12345 You can actually use it without the Spawner, if you make a duplicate of your DataAsset and delete the CrowdVisualization from it and add the DataAsset to the MassAgent in BP_Character, you can just hand place the BP_Character and the MassAI works, but I dont know how it works in sequencer..
@@viperdkue5 I tried that but it only spawned the character itself. It didn't show any characters, apart from the one of the BP itself. If it did work it might be the solution because I can track blueprints directly from sequencer. It would be like a BP that would trigger the crowd simulation. So far, I wasn't able to make it work. Maybe I did something wrong
A warning needs to be given to not run this on a (custom) city sample project. The suggested changes screw up the included crowd character which can't be repaired. It made my project unusable and now I have to redo the work of two weeks.
If anyone has an error where Set Groom Asset function is missing or you only get warnings to add 2 plugins and not 3, add the groom plugin to your project manually.
Turn on all the "Groom" plugins to fix it.

thanks for these tutorials! will you make a more complex tutorial for vehicles? (To change their color and make the lights work)
Yes, I will try and make a video about it soon .
i got this error Some traits are requiring the presence of fragments which are missing!
First of all - Many Thanks for a wonderful tutorial ! Really Really appreciate your work ! As I belive many with me would like you to do an updated version for 5.2 because I don´t believe there are one person here that use 5.2 that has it working....I got 60 Errors when compiling - And that is just to much to be resolved....Like many others here there are problems with Mustache, Beard and Hair but also "Set Grooms Material". I tried what people have suggested here - but no luck. So please please - Could you make a New tutorilar for 5.2 - Because of Nanites nearly everyone will use 5.2 soon i guess....
IF someone here has a working version - An example of the Mass Crowd working (Not the city sample...) it would be much appreciated to be able to download or in some way understand how you got it working....
Kind Regards
I'm running into the same issues with 5.2 and would also like to see an updated tutorial.
Same here got rid of all warnings, but when it comes to simulate, nothing happens got an error, cant recall what it said as i deleted , but it was to do with missing fragments on the stat tree, but i couldn't figure it out
I got it working in 5.3.2, added some notes on what needed to be done in addition to following the video in my other comment.
@@mickmeenan if you literally add all the missing fragments mentioned in the error message to the Crowd Data asset it should work
@@liampugh how?
Hii, thanks for the tutorial! It´s almost working in 5.1, but I think the walking animation isn´t looping. I guess it´s because I can´t find where to put the things of the 5.1 screenshots : ABP_Crowd-SeguencerPlayer-Details
Where can I find that panel?
Thanks!!!!
me too. all working execept that ;< please help me
Hey,
Thank for the tutorial, I am facing an issue that i can't find a fix for,
following ur method on 5.2 worked like a charm
but this doesn't work on 5.3 it just keep crashing once i open the BP_CrowdCharacter ( causing a rash with Rigvm and multiple other things)
IDK what to do to get it to work on 5.3
Great tutorial. Can we have another vehicle tutorial? Because the current use method seems to be different from the previous vehicle tutorial.
hey bro if i use this in level sequencer for animation so this method work ? am beginer bro thanks in advance
Hello, I dont think the Spawner works in sequencer, but you can hand place the characters on the Zoneshapes and it should work ^^
same issue
@@naytbreeze so did you try this method ? It work in sequencer or not ?
@@arshankhan6833 Some suggested I follow this video instead to get the animations into a tape recorder. Going to try today. th-cam.com/video/9MLjstChfDM/w-d-xo.html
@@arshankhan6833 I'm beginner too, for a single character to work in sequencer look at my comment to Rui Marques
In my component panel face don't have mustache, beard and hair.
can you please help me here ?
Thanks a lot!
Can you remake the video for Unreal Engine 5.2?
Thanks for the tutorial. It all went well, but at 9:20 I couldn't select the state tree that I made, somehow the Mass Entity Config doesn't see my state tree. Any help is appreciated. Thanks!
I got round this by clicking Create State Tree from inside the Entity Config and that was the only way I could get it in there.
@@qntmstudios1214 This not working for me, if I create a new one here, it still doesn't get added.
@@qntmstudios1214 Actually it worked if I chose the MassStateTreeSchema
@@ElectricLoft I Haven't tried it yet but I will give it a shot when I have some time. Thanks!
How come the MassEntityConfigAsset doesn't require a ZoneGraphAnnotation trait here?
It is only needed for the Danger Annotation and we don't use that atm.. combined with the MassAI traffic, traffic can add a Danger Annotation to a Zone and Pedestrians will avoid that zone. Later on I will look at making my own annotations, but ZoneGraphAnnotation only comes with the Danger annotation build in..
@@viperdkue5 Ahh gotcha, thanks.
Any idea what would cause the peds to keep moving in their initial direction, but the mesh rotates in the direction the mass agent is moving in? When the ped comes to a corner, the mass agent debug panel moves along the path, and the mesh does rotate towards the new lane orientation, but keeps moving in the direction it was going. This makes it look as if the ped is walking sideways. Almost as if the velocity is not being synchronized from the Mass Entity to the actual ped.
The three traits are setup identical as in the video (Capsule Collision Sync: No Sync Transform + Actor to Mass) / Movement & Orientation Sync: Mass to Actor.
@@artofcode yeah, I have had that happen to, maybe try and set Movement sync to both ways and see it it helps..
@@viperdkue5 Tried that, but didn't make a difference. Did some more digging and found out that the Character is in a falling state, causing the velocity that it receives to not be applied as we wanted (can't move forward if you're not touching the ground). So when I find out why it's not touching/detecting the ground, this will most likely be resolved.
Okay, the sounds weird.. maybe try and change the capsule collision to sync transform, if you use the AIDebug and press shift G and select a character, you can see where the capsule collision is.
Big thanks!! I'm trying to make a little cyberpunk street. What do you think is the best practice to make use of this and change pedestrians to cyberpunk look?
Just use your Cyberpunk Character and add mass agent to it :)
Great tutorial, thank you! How would we make this pedestrian system with EQS? Can you use behavior trees instead of state trees?
I dont think so :S Have a look at this th-cam.com/video/w7zs7-oI2_I/w-d-xo.html
Great tutorial! It works for newbie like me! But is there any way to make the crowd not collide with each other? The original crowd from ue5 City sample have a sensor which make them not colliding with each other
Unfortunately, it's not working for me in 5.3.
life saver
Isn't the point of Mass to not use expensive actors like Character for everything? This setup looks like it won't scale up to lots of entities.
Not really, because MassAI limits the amount of high res actors that is visible on the screen and use low res actors at a distance and we can use a static mesh with vertex animation material at far distance. off screen there is no actor, just the MassAI agent that is highly optimized.. In the City sample project they use thousands of characters, so it works at scale, if you setup it right..
@@viperdkue5 Right, but you used BP_CrowdCharacter as your low res actor in the video.
@@SonicTheCat When BP_CrowdCharacter is used as low res it Ticks at a lower rate, if you add a SimulationLOD Trait and enable Variable Ticking and this is just a quick getting started guide, its the same way EPIC does it in the Matrix demo, but yeah it can be optimized a lot more, I think its one of the main reasons the Matrix demo runs at so low FPS..
@@viperdkue5 This part shocked me too. I think you should also talk about the optimisation process because nobody wants max res metahumans being rendered when they don't need to be
Thank you Thank you Thank youuuu!
Awesome tutorial !!! Btw let’s say I need to edit the route of the people do I need to redo the whole thing ? Or can I just edit the path somehow?
In the Editor you can edit the zoneshapes and and click rebuild Zonegraph, In the Game we can not edit the Zoneshapes, maybe in the future.
LogMass: Error: Trying to extract CharacterMovementComponent from BP_CrowdCharacter_C_0 failed
OK I waa sent here from your other video. I followed this one and now no characters spawn at all when I press play.
I followed every step correctly, even had to rewatch to check Mistakes, but when I run the simulation, it says some fragments are missing and idk which ones are
ME,TOO
did you figure it out?
@chillchillshit nope I haven't. I decided to focus on other things until someone responded with a solution
Groom elements are not showing in my project what should I do?
As soon as I “Reparent” the skeletal mesh disappears and I receive different errors than the ones you show here. No good.
not work with 5.1 :(
Couldn't make it work either
I just did a test on 5.1 and it seems you need to enable Groom plugin manually then City Sample Crowd works normally. I'm still testing MassAI in 5.1 but think we just need to remove some traits/fragments and add other traits/fragments and it works like in 5.0.
Go to see the "Newest Comments" in this video comment section, there you will see a thread with 8 + replies
What do we do if we dont want them to follow a spline, but rather follow the player?
I got a question. When you set this up, do they show up in sequencer as well? or only in play mode?
thanks for this! working great. However.... holy shit, i wish it was a bit easier. If it wasn´t for this tutorial i wouldn´t have a clue how to get it working.
Nice! Is it possible to make these MassAI to do daily tasks such as go to bed at night then wake up in the morning and go to work, then repeat.
Thank for your tutorials, it works fine on 5.1. Just wondering how we can assign another animation/behavior of these characters, not just walking only.
I think you'd need to assign that animation through the character's Anim Blueprint
What about the warning "Usage of 'SkeletalMesh' has been deprecated"? How can it be fixed in 5.1?
Okay, that's fixed.
How??@@sascha.
@@dunne54321 I finished that project about half a year ago. Sorry, I totally forgot what I did to resolve the warning.
Thanks fort sharing. I have a question, why did you switched the LOD representation to High on all?
If you don't put it on high, you need to add a mesh with textureanimation, and it didn't really work at the time.
Thank you I appreciate!@@viperdkue5
Is it possible for mass AI to detect damage then send messages to regular AI?
Mass AI is only for movement, so you can still use the BP Actors as normal ^^
Thanks
I tried to solve the traits problem, following the link..but I can't find in the "CrowdAgent" editor the traits = Transform Fragments and Agent Radius Fragments".
So the result is always the same, when I do Play nothing happens and it keeps reporting the Traits problem. I use EU 5.2
under"assorted fragments",add a new index. You'll see.
@@genieeye5783 Unfortunately it doesn't work, when I do Play no character appears and the message "some fragments are added by multiple traits and can only be added by one" appears.
How is the performance of Mass when let´s say moving around 1000 agents and 10k agents?
Hi I am new to unreal engine. and i wonder how can we add these crowd in level sequence and make a cinematic camera and render it. becauez the crowd only emits when we hit play button. what if we are making a short film and have to add crowd in a shot. how can we do it? Can't we emit crowd without hitting play button and add them in level sequencer so that we can render them. please reply if you can i am stuck in there, i don't know how to do it. thanks.
Hey Abhishek, im also trying to do the same thing and stuck, did you find a way to get them into sequencer??
@@dan2059 I got the solution. simulation will automatically trigger when we render it. we can't see it in the camera view while scrubbing in level sequencer but it will be shown in the final render.
@@abhishekbasiwal3thank you! So if we can’t scrub through it, then there would be no way to animate a car weaving through traffic without doing it in PIE, right?
@@jobegruen4273 Yes, Crowd will emit in final render only. Or maybe there is other workaround with blueprint but i have no idea about that as i am not that good in blueprints.
@@abhishekbasiwal3 that makes two of us! Thank you for replying!
Hi, thanks for this helpful tutorial. May I ask what can I do to assign another animation/behavior of other characters, not just walking behavior? I tried making a duplicate of the ABP_Crowd and change the animation but somehow it doesn't work. Thanks in advance for your reply.
How to do this with city sample vehicle? Will it work similar? Any help is appreciated.

Hi. Amazing video, by the way. Is there a way to activate the crowd mass ai when doing a movie in sequencer? I tried to track pretty much everything I thought that might work, but I had no luck with that. Can you help with that, or does anyone know something about this?
I dont know, I have never used the sequencer, but I'll give it a try.
@@viperdkue5 I think there might be a way to trigger an event in sequencer that activates other events on a blueprint. The thing is the crowd mass is working based on event begin play. I'm trying to do that in sequencer. If you have a BP_character, you can track it on sequencer. When they spawn on event begin play, you don't have them on the outliner
@@ruimarques12345 You can actually use it without the Spawner, if you make a duplicate of your DataAsset and delete the CrowdVisualization from it and add the DataAsset to the MassAgent in BP_Character, you can just hand place the BP_Character and the MassAI works, but I dont know how it works in sequencer..
@@viperdkue5 I tried that but it only spawned the character itself. It didn't show any characters, apart from the one of the BP itself. If it did work it might be the solution because I can track blueprints directly from sequencer. It would be like a BP that would trigger the crowd simulation. So far, I wasn't able to make it work. Maybe I did something wrong
@@ruimarques12345 Hey Rui, I am in same situation as you were and I couldn't make it work so far, any success?
A warning needs to be given to not run this on a (custom) city sample project. The suggested changes screw up the included crowd character which can't be repaired. It made my project unusable and now I have to redo the work of two weeks.
whatever happens we never do a test on a version without backup
or you do the tests on a blank version I'm sorry for you
Do you have blueprint road? I try to find it few months ago, but still didn't find it yet.
Hi master~ thx for the demo. I have a question for this simulation. Can we change the metahuman actors to other type of characters? Thank you
Yes, you can use any character you want with Crowd, and any StaticMeshs if you use just the MassAI.
i cant seem to figure out why but the mass spawner is not spawning anything
Mass agent movement sync and Mass movement trait collide by adding the same fragment.
thanks for the tutorial
Thanks.. Like 100's or 1000's, then yeah I would use MassAI for that, but you have to write your own c++ traits and use EQS
Have a look at this th-cam.com/video/w7zs7-oI2_I/w-d-xo.html
@@viperdkue5 WOW! Thanks a lot! I wasn't know EQS. I'll do r&g for it.
Thanks Bro
