For advanced usage of the postprocessing library we also provide the option to have full manual control over the library. This means that the effect composer can be used as you wish and you can add passes and effects in any way you like.
In the first step, you need to enable the
manualPostProcessing property. Then you can add passes and effects in any way you want. In the example below you can see how to add the pixelation effect yourself, without the use of the API. This makes it possible for you to have full control over the post-processing.
