Postprocessing Outline Effect

[neurodraft]

Hello, really enjoying working with the library. Recently have been recreating a project in version 2 and testing the beta.
Playing around with the effects included in the postprocessing library for angular-three and looking at the original postprocessing library documentation left me wanting to use the OutlineEffect (I know it isn't very optimized etc) but wasn't able to make it work correctly with the NgtEffectComposer. The effect was added to the EffectsPass after porting it following the SSAOEffect source but only renders black.

Since this effect wasn't added originally, does anyone know the reason it wouldn't work?

Thank you very much in advance!
