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.

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
