Effectors make the scene react to the cursor (or a position). One effector can push/pull particles, drive an object’s transform, and modulate a post-FX parameter — all from where the pointer is in 3D.
Where: 3D editor → Add → Effector — Add an effector and bind it
Key ideas
- Follow the pointer: The effector raycasts the cursor into the 3D scene (with smoothing), or stays at its own position.
- Particle force: attract / repel / vortex / turbulence / drag within a radius + falloff.
- Object & post-FX binds: Ease a target node’s position/rotation (per-axis + clamp), and drive a post-pass param from cursor distance/proximity/x/y — e.g. DOF focus follows the cursor.
Steps
- Add an effector and set it to follow the pointer.
- Enable the particle force (type/radius/strength).
- Optionally bind it to an object’s transform or a post-FX param.
