    HI,
    I search a way to have a glow effect but important and in a small area (around an object)
    You Have in image one the normal scene lightning :

    Now the version with volume Bloom :
    Capture d’écran (65).png

    The effect around the torus is what I wan't but All object in scene with a "light" color (not dark) axplode. How I can limit the effect ?
    I have check. All materials and objects are separated it's not a linked object dupicated.
    It's used with Universal Render Pipeline. I have only one directionnal light in scene with a "flat" position (perpendicular to the board to remove shadow and specular)
    Thanks
    Thibaut

    Instead of bloom, make a texture of a blurry ring on black back ground. put it on a quad with an additive particle shader.
     
    BrandyStarbrite and Olmi like this.

    If you've got HDR enabled, you can increase the bloom threshold value to 1.0 or higher - so normally-lit objects produce no/less bloom

    Then to create a strongly-blooming object, give it a brighter-than-1.0 HDR emissive colour
