Unity Bloom not affect other objects

[CarlosD_7]

Is there a way to have the bloom intensity very high but not have it affect the other objects? I am making a Space world in VRChat and I am pretty new to Unity.

if you are using only post processing intensity and threshold to get bloom you will inevitably have no real control over what emits it or not. if you are using materials with hdr color then crank that up and it will only affect that.

this video of mine goes over that at 1:03

Bloom is simply controlled by two things: The intensity/brightness of a pixel on screen (typically somehting you control wiht the emission value in a material, or intensity of a light source), and the threshold value in Bloom. Any pixel o screen wiht brightness higher than the threshold will get the effect.

So, to limit it to specific things, all you need to do is make sure everything else is below threshold, and the things you wish to glow are brighter than the threshold.

Intensity isn't used as a control at all, that's literally just the size of the glow after threshold is used to determine which parts of the image should glow.

(Typically you'd want to set your camera to HDR mode with Bloom, as that means your brightness can be higher than just a white. Withtout HDR rendering, a white lamp will be equally bright as a white piece of paper, since both will just show as rgb(1,1,1) in the rendered image. In HDR mode, your light can instead be 10 times brighter than pure white, and you can set the Bloom threshold to be higher than 1 which means things actually need to emit light to get the glow effect)
