Kaan_Altay,

The simplest solution would be to SubClass your USkillTreeComp from USceneComponent (Class USkillTreeComp : public USceneComponent).

Hey thank you for that can you explain how can i do that?

You’re welcome,

In your header file for the USkillTreeComp - just replace the class that it is subclassed to with USceneComponent - it’s probably something like UActorComponent or UComponent:

so it will look something like:

UCLASS(blah)
class USkillTreeComp : public UScene Component
{
GENERATED_BODY
…
