4.7.6 Spawning Actors on Server Warning Spam

Under 4.7.6, when I spawn an actor on server, I get following Warning spam:

LogNetPackageMap:Warning: UPackageMapClient::InternalLoadObject: Unable to resolve default guid from client: PathName: Block1_C_112, ObjOuter: /Game/ThirdPersonBP/Maps/UEDPIE_1_ThirdPersonExampleMap.ThirdPersonExampleMap:PersistentLevel
LogNetPackageMap:Warning: UPackageMapClient::InternalLoadObject: Unable to resolve default guid from client: PathName: Cube, ObjOuter: NULL
LogNetPlayerMovement:Warning: ClientAdjustPosition_Implementation could not resolve new relative movement base actor, ignoring server correction!

It keeps generating these messages continuously as long as server is running.

Here’s my full log:

Hi

I wasn’t able to reproduce this warning in 4.7.6. To test, I created a new Actor Blueprint with a Static Mesh component, and spawned it at Begin Play in Level Blueprint. I tried spawning same Actor on a Listen Server using Server’s Character BP, and that didn’t log a warning either.

Does this occur in a new project, or only your current project? Does this occur when spawning any type of Actor, or only a particular Actor? Can you provide some more details on Actor you are spawning? What method, and from where, are you spawning Actor? Any additional details, screenshots or a test project to help us reproduce this would be appreciated. Thanks!

I’ll just send you entire test project, what is best way to do that? up entire project directory and e-mail it?

Easiest way for us is if you can upload it to Dropbox or Google Drive (both free) and give us a download link. You can send link to me via PM on forums if you’d prefer it to remain private:

Thanks again - message sent.

Thanks for project! I can confirm I’m getting same warning. It appears to be caused by Cube static mesh component in Block1. I haven’t been able to figure out exactly why, yet, and I’ve forwarded project link to network team to see if they can spot problem. I’ll let you know when I have some more information for you.

That’s exactly what I saw, but can’t trace down why either. I appreciate you taking a look at it.

Looks like this issue has been around for awhile (September, 2014). I’m getting same error as reported here whenever my player collides (specifically when it walks on) an actor that was spawned by server.

I have a very similar problem, as you can see in this thread Client gets disconnected when touching mesh - C++ - Epic Developer Community Forums. Have you been able to resolve this issue?

I just had a look into engines source code and above lines that are causing there is an interesting comment:

// Make sure base actor exists on this client.

If it doesn’t, log will be printed, so it seems that base actor doesn’t exists on client. Does that mean that if we spawn an actor for collision on server we also have to spawn same on client (which would make sense) and connect their reference/pointer somewhere somehow?

I believe when an actor is spawned on server, then as long as actor is set to “Replicates” (which in my case, they are), then clients are also supposed to instantiate actor.

Hey, just wanted to let you know that we’re still looking into what’s causing this. I’ll let you know as soon as I have something for you.

As I wrote I had a very similar problem and I think my solution might work for you as well, as " (specifically when it walks on) an actor that was spawned by server." this was exactly issue I had, when I was walking as a client on a serverside spawned mesh.

My solution for that was that I not only had to replicate actor mesh is attached to but I halso had to replicate subobject (mesh) itself.
I think that problem then is, that mesh is attached to an replicated actor, which is why it does work at all, but engine can’t resolve a net guid as mesh itself isn’t replicated.

Hi

Thanks again for project. We weren’t able to come up with a simple solution to warning spam, so I’ve entered a bug report for issue (UE-15618). I’ll let you know when I see any update on it or if we come up with any workarounds in meantime.

Great, thanks!

@, I am experiencing this issue in my game as well which is very simple otherwise if you’re interested in grabbing my project for testing reasons, let me know if it would help.

Thanks! I’ll let you know if devs ask for more information.

Hi , same issue in 4.8.1 for me. In my case, I get this error on server (OS X) when I connect with an android client. Connecting with another OS X client is ok. Generally removing app from android device and reinstalling it or repackaging it fixes problem (probably sometimes there are objects that are modified but not correctly re-deployed)

Please let me know if you need more details about issue.

This may be a red herring. But I was having a similar problem when testing in editor as client.

If map I had loaded in editor was same as map server was using I would get this warning spam on connect. If I loaded a different map in editor first everything went fine.

Bumping this up as I have experienced same issue when spawning local actors
