inputPreviousStageTexture
All post-process stages are executed in the order of the array. The input texture changes based on the value of inputPreviousStageTexture. If inputPreviousStageTexture is true, the input to each stage is the output texture rendered to by the scene or of the stage that executed before it. If inputPreviousStageTexture is false, the input texture is the same for each stage in the composite. The input texture is the texture rendered to by the scene or the output texture of the previous stage.
