Selective bloom not working

This is a different approach, but also see:

How to render a scene with 2 different UnrealBloom effects applied on2 different Object3D?

Bloom is a screen-space effect — trying to apply it per-object is going to be a lot of trouble, particularly with a threshold of 0. Instead of two passes with different strengths, consider making these materials (much) brighter … material1.color.setRGB( 1000, 0, 0 ); material2.color.setRGB( 0, 500, 0 ); … then use a single bloom pass and set the threshold to something larger than one. The goal here is to choose color intensities and a threshold high enough that non-emissive objects (even if th…

My feeling is that getting your “emissive” objects and bloom threshold above the 0–1 range is generally a better approach, and avoids the need for manual selectivity.
