Diving Into Niagara: Intelligent Particle Effects
summary
Niagara 4.25 walkthrough shows six concrete VFX builds: a burst-spawned deck of cards that uses skeletal mesh bone positions (execution index equals bone) to form a pyramid, curl-noise and velocity curves to animate return, and thousands-strong world particles that use an occlusion query with tunable sample rings and samples per ring and sample window diameter to lerp visibility from the depth buffer. Also covered: sphere-cast global distance fields for surface-aware forces, the attribute reader to link emitters, and debugging via the Attribute Spreadsheet and dynamic material parameters.
