Some more considerations for post processing:
- some passes need to be in linear space (before tone-mapping) and some need to be done after. Some can be done before or after but you’ll get different results (e.g. vignette).
- Outline effect looks like it has tone mapping built in (probably incorrect?)
Before tone mappings: bloom, lensflare etc
Then, in order: 1. tonemapping 2. gamma correction
After tone mapping: brightness, contrast, FXAA, SMAA, color correction
Order not important (or, choose what looks best to you): DOF, vignette, film grain etc.
I’m not sure where where exposure comes into this - either before all passes, or just before tone mapping?
Thoughts:
- We should remove all tone mapping except for ACESFilmic/NoToneMapping. ACES Filmic is the industry standard and as far as I know the only kind of tone mapping Unreal and Unity support. I have so far not seen any arguments for having other kinds of tone mapping.

It would be great if a final tone mapping pass was automatic when using the EffectComposer. Even better, combine color correction/tonemapping/brightness/contrast as the final pass (again, that’s what Unreal does I think)(see below). - have post processing built into the core so it’s a first class three.js citizen - see Takahirox’s PR here:
