You might not need post-processing
When to use post-processing and when a simpler approach wins.
Please note that you can use TresJS's attach feature instead of this module. It enables you to utilize any effect provided by Three.js, even if there is no corresponding component in post-processing.
We recommend using post-processing because the props of the effects are reactive. The attach feature does not offer prop reactivity. However, if you do not require that advantage, it is a valid option to achieve equal results.
