UTGameCrowdAgent Log Error | Error: Can't call UpdateRBBonesFromSpaceBases() |NpActor

[exittoexist]

I'm getting this error in every tick, and it results in 200mb log files as there are 30-40 agents active on the map and this error always loops for all the agents.

[0108.13] Error: Can't call UpdateRBBonesFromSpaceBases() on (UTGameCrowdAgent_151)->(SkeletalMeshComponent_216) during async work!

I will be very glad if someone can help me on this.
The 'bishop_crowd' archetype is the same as the default one, instead it has a physic asset assigned and the collision settings are like this:


and the kismet properties if its relevant


Also; At UTGameCrowdAgent.uc there is a line:
SkeletalMeshComponent.UpdateRBBonesFromSpaceBases( TRUE, TRUE);

Is the error about this value?

[exittoexist]

I'll have to bump this, sorry.

[exittoexist]

The default tick method of UTGameCrowdAgent is TG_PostAsyncGroup

ON UDN it says that: If it changes collision, spawns collidable actors, writes to Novodex data, then it should go in TG_PreAsyncWork

So i did this, but i'm getting the same error. Is this error related to the code of utgamecrowdagent.uc?

[exittoexist]

another bump.

Did you change the tick group of both the actor and the mesh component?

[exittoexist]

Did you change the tick group of both the actor and the mesh component?

Just seen the reply. When the error started to happen the tick group of the actor and mesh component were at their default settings (same as Bishop Crowd Archetype that spawns the robot)

[Spoof]

Is this all Kismet or do you have unreal script affecting it?

Logically, something is attempting to call UpdateRBBonesFromSpaceBases() during the asynchronous phase while physics is still simulating. The tickgroup of the actor and component seem to be correct, so it's likely that another actor using TG_DuringAsyncWork is trying to call the function through a reference to the agent.

[Spoof]

The default tick method of UTGameCrowdAgent is TG_PostAsyncGroup

I just checked the API and the default, for both actor and skeletal mesh component, is TG_DuringAsyncWork.

[exittoexist]

I just checked the API and the default, for both actor and skeletal mesh component, is TG_DuringAsyncWork.

Thanks for the reply. I haven't tried changing UTGameCrowdAgent.uc after seeing the log errors. The error is either caused by the bishop_crowd archetype settings ( which i use the default values of the Robot) , the Kismet or the code.

I even tried spawning an animal mesh [it was snake i think] with the mobile crowd system , and i got the same error.
