MassNavMeshPathFollowTask Error​

This error means an entity can not walk to they location it was told to go to because of possible reasons:

  • the NavMesh is not connected to the walk target location
  • there is no NavMesh at walk target
  • An entity has been pushed away from the NavMesh (usually collision)

It can happen due to loss of framerate, making entities not navigate properly. Note: framerate is much better in shipped builds

Large FPS drain on play​

First check if you have any StateTree windows open, when they are open and debug is enabled a lot of data is saved every frame which causes performance issues.

Entities not moving​

First check that the NavMesh is on the entity path and that the entity is on the NavMesh

Visual bug on entities​

If your material looks like this first try to load them by opening the materials

If it keeps looking this way rebake

WPO issue on Static Meshes

How to rebake​

Delete the files for your Vertex Animation in the plugin DataFolder

Then bake on a character or actor and set the skeletal mesh on your BP_Smb_Bake_Component

Alt tab floating​

When alt tabing the entities may start floating and will attempt to recover their location.

DeathPhysicsFragment type not recognised​

This is an error that is being worked on, it is likely due to StaticMeshes not being loaded when entities spawn.

Ability Sounds and VFX missing​

Sounds and VFX for skills need to be loaded before they are used by entities. Ensure they load into the level first.
