Selectively applying a bloom filter to objects in a scene seems like a good use for multiple layers: [http://jsfiddle.net/prisoner849/mjfckw02/](http://jsfiddle.net/prisoner849/mjfckw02/) (from [this thread](https://discourse.threejs.org/t/solved-effectcomposer-layers/3158))

If there’s a way to accomplish this without multiple layers though, I’d like to hear about it!
