재현 방법
- Create a Niagara system using the built-in Fountain template.
- Place the Fountain actor at a location other than the world origin (0,0,0).
- In the Fountain emitter, set the Position Mode in the Initialize Particle module to Unset.
- Observe that particles now spawn at the world origin (0,0,0).
- When performing steps 1–3 in Unreal Engine 5.4, particles correctly spawn at the location of the Niagara actor, not the world origin.
