react-postprocessing is a postprocessing wrapper for @react-three/fiber. This is not (yet) meant for complex orchestration of effects, but can save you hundreds of LOC for a straight forward effects-chain. This library provides an EffectPass which automatically organizes and merges any given combination of effects. This minimizes the amount of render operations and makes it possible to combine many effects without the performance penalties of traditional pass chaining. Additionally, every effect can choose its own blend function.
