Hi guys,

I’ve been trying to package my game for the past couple of days on both UE5.1 and UE5.2 thing is, I’ve run into an error that’s stopping me from compiling:

Before this error I had been faced with an error about MetaHumans which I have experienced before. The way I solved this error was by doing what this post had said. Thing is upon doing this, I was faced with other errors which I am unsure if they are related.

If anyone has any insight on how to fix this, it would be much appreciated

SetLeaderPoseComponent detected loop (the input Leader pose chain point to itself. (Mesh ← Mesh))

It seems like you might have the same mesh component hooked up to the SetLeaderPoseComponent’s “target” pin and “New Leader Bone Component” pin.

The Leader Bone component is the one driving the meshes that go into the target node.
If you hook it up to both you cause an infinite loop.

You need to unhook the main body part from the target pin of SetLeaderPoseComponent.

You’re absolutely right,

I just looked up all references of SetLeaderPoseComponent, located the issue which was Mesh connecting into SetLeaderPoseComponent, and same with a Mesh2 that also had the same issue.

Fixed my issue, thank you!
