Prefab Interactable Components Failing When Spawned at Runtime

[Nman_Pkr]

Summary

I’m seeing unreliable behavior when using Scene Graph prefabs that contain meshes + interact logic. Prefabs that work fine WHEN PLACED in the editor often break or behave inconsistently when spawned at runtime via Verse.

Rebuilding the same object dynamically in Verse (instead of using a prefab) appears to be significantly more reliable.

What Type of Bug are you experiencing?

Stability

Steps to Reproduce

Create a prefab that includes a mesh and an interactable component.

Spawn it at runtime with Verse.

Attempt to interact with it.

Expected Result

Runtime-spawned prefab should behave the same as an editor-placed version and interactions should fire normally.

Observed Result

Intermittent issues such as:

interaction prompt does not appear at all

success events don’t fire

Multiple creators appear to be running into similar problems.

Platform(s)

UEFN / PC

Additional Notes

Workaround: Building the entity from scratch in Verse has been much more stable than spawning prefabs.

Example pattern:

MakeObject() : entity =
    Obj := entity{}
    Mesh := MyMeshComponent{Entity:=entity{}}
    Obj.AddComponents(array{Mesh})

    Interact := YourSubTypeBasicInteractableComponent{Entity:=Obj}
    Obj.AddComponents(array{Interact})

    return Obj

Then spawn normally:

if(Sim := Entity.GetSimulationEntity[]):
    NewObj := MakeObject()
    Sim.AddEntities(array{NewObj})

Would be great to know if prefab runtime parity is expected or if there is a recommended best practice here.

Summary I have a map built from scene graph prefabs, but I am not able to build on them (Fortnite builds) nor interact with it with fortnite items (ex: Grapple, throwable items, etc). Please refer the screenshots for the settings. Also to note, the mesh itself does work properly, but once it is in a prefab, the issues come up again.

Component Not Working as Intended - Scene Graph

Summary Not sure if this is in documentation but I haven’t found it but when spawning a prefab that has prefabs inside of it . my key frames for animating aren’t working. The animation plays but the visual of animation doesn’t so the collision will work but visually the entity will look out of place. I have found that if I place the prefab in the editor and then spawn another of the same prefab it seems to work. Not sure if this is intended or not. to be clear I already have a different prefab i…

Severe Performance Degradation When Adding/Removing Prefab Entities After UEFN V38.0 Update

After update V38.0, adding and removing entities in the world started to cause severe server degradation. I’m developing a procedural system that relies on spawning and removing Prefabs dynamically. Each prefab contains several child entities with components (static meshes, logic, etc.). Before this update everything worked fine but now the performance cost increased drastically. Using Verse profiling, the average cost to add just 1 prefab to the world is now around 300 ms, and the value kee…

I have never had a issue with interaction comps tbh ? the one thing i do tho is have a comp setup with a sphere mesh for the interaction i never use the mesh itelf. The mesh should have collision on with the type being the overlap only pawn collision setting.

If you need some snips let me know as ive never had an issue doing it this way.
