- class unreal.NiagaraSpriteFacingMode¶
This enum decides how a sprite particle will orient its “facing” axis. Must keep these in sync with NiagaraSpriteVertexFactory.ush
The sprite billboard faces toward the “Particles.SpriteFacing” vector attribute. If the “Particles.SpriteFacing” attribute is missing, this falls back to FaceCamera mode.
The sprite billboard origin is always “looking at” the camera origin, trying to keep its up axis aligned to the camera’s up axis.
Blends between FaceCamera and FaceCameraPosition.
The sprite billboard plane is completely parallel to the camera plane. Particle always looks “flat”
Faces the camera position, but is not dependent on the camera rotation. This method produces more stable particles under camera rotation. Uses the up axis of (0,0,1).
