Class EffectLayer

The effect layer Helps adding post process effect blended with the main pass.

This can be for instance use to generate glow or highlight effects on the scene.

The effect layer class can not be used directly and is intented to inherited from to be customized per effects.

    • name: string

      The name of the layer

    • scene: Scene

      The scene to use the layer in

    Returns EffectLayer
