In version 5.1, nothing happens, NPCs do not spawn ( Some fragments are added by multiple traits and can only be added by one! Some traits are requiring the presence of fragments which are missing! See the log for details LogOutputDevice: Error: Ensure condition failed: UE::MassBehavior::SetExternalFragments(StateTreeContext, StateTreeContext.GetEntityManager()) [File:D:\build\++UE5\Sync\Engine\Plugins\AI\MassAI\Source\MassAIBehavior\Private\MassStateTreeProcessors.cpp] [Line: 174] LogOutputDevice: Error: StateTree will not execute due to missing required fragments.

I have the same problem. Have you solved it?

I found a solution that worked for me. You will still get one of the errors, but the system runs and the actors spawn in. Search the video "UE5 Tutorial MassAI Crowd in any project in less then 15 mins." by Viperdk UE5 and in the description look for the link next to "Traits for 5.1.1" I added the extra few fragments to the DA (Transform Fragment, Agent Radius Fragment, LODCollector, and SimulationLOD) and added the 2 traits (Agent Movement Sync and Agent Orientation Sync) to the MassAgent component in the character BP. I don't know if those are all truly necessary, but adding those worked for me. Good luck!

This is amazing. You can easily make them move only in one direction, right?

Thanks SO much! Yours is the only video that I have found that explains what the individual components do.

would love to see a tutorial for setting up with the city sample crowd (particularly in version 5.1) utilising the random ai generation - i followed the tutorial with that in mind but found the errors "Some fragments are added by multiple traits and can only be added by one!" and "Some traits are requiring the presence of fragments which are missing!" Edit: actually the errors might be a 5.1 thing as i tried it again with the third person character and the same errors came up.

no i have figured out that you have to add in assorted fragment the following mass viewer info fragment transform fragment agent radius fragment these in addition to the one he added mass actor fragment this should solve your error

Hi, do you have a continuation of this tutorial? I kept looking on this video on how to add a custom character, as what your title says. I only see the UE5 third person character being added. I think UE5 Third Person character is not a custom character, it is a generic character.

When i drop my same manny character in i get weird LOD issues where the animation and mesh is glitchy at a certain distance. Anybody run into this and have a fix?

Very interesting tutorial. My goal is to make a stadium or concert crowd with it. So what is the way to use animated but standing in place characters, and placed into bleachers?
