Combining Effects

Layer and blend multiple effects using the AOS Blueprint Actor

The AOS Blueprint Actor

The central tool for combining, grouping, and managing multiple post-process effects. Place one actor to control many effects — no need for multiple Post Process Volumes.

Effect Groups

Main EffectsPrimary visuals applied to main scene objects, controlled by scene depth
Background EffectsEffects only on distant background elements, depth-threshold controlled
Screen EffectsFull-screen effects — camera lens, overall colour grading, screen-space distortions
