Hi guys I am struggling in getting a selective bloom (maybe I am using the wrong tool for the job or I misunderstood how it works…). What I want to achieve: Model blooming the same color as the emissive texture (without manually setting it, so the color is taken straight from the emissive image) …

Hi! Maybe this topic will be helpful: https://discourse.threejs.org/t/selective-bloom-not-working-in-separate-files/30289/3

here’s an example Selective outlines - CodeSandbox but generally postprocessing works a little differently and using an emissivemap with some kind of blur shader is probably best but that’s not what pp does.

Hi Guys thanks for replying, to clarify even further what I want to achieve is a result similar to the one below: [telegram-cloud-photo-size-4-5989963912050751575-x] given by the following textures (emissive + color): [telegram-cloud-photo-size-4-5989963912050751593-y] [telegram-cloud-photo-s…

Hi mate, thx for the reply! It seems the page is 404 for me for some reason

Ah, so we would need custom shaders/fragments in order to achieve that kind of bloom/glow effect out of emissives? Babylon’s seems to have it out of the box, I will play around with those fragment/shaders (and try to understand how they can be integrated into the from @react-three/postprocessing, …

i dont quite understand why this is not in threejs. feed the material that map, blur and overlay it. though i don’t know anything about shaders so there sure must be a catch.

this looks great! would the same be possible without rendering the scene twice? could a generic standardmaterial with some onbeforecompile replace perhaps just multiply a blurred texture? and can shaders affect stuff outside of the mesh region?

Just to clarify as I am quite new, and as you are the lib author who’s better than you to ask ahaha. Would there be a declarative simple way to achieve what I want using react-postprocessing? @drcmda

i dont quite understand why this is not in threejs. feed the material that map, blur and overlay it. Just takes someone with a need to build it and make a PR :man_shrugging: feed the material that map, blur and overlay it. I think normally what you want for this kind of bloom is HDR rendering…
