[PostProcess]Is that a feature or a bug?

Unity Engine
1

1.Create a Empty,set layer = “a”,addComponent Post Process Layer,set(Camera) Clear Flags = “Depth Only”,Culling Mask = “a”,Post Process - VolumeBlending.Layer = “a”
2.Create a 3D> PostProcessVolume,set layer=“a”,check IsGlobal=“true”,Weight=1, new a Profile, add “Bloom”,check: intensity + Soft=1 + Diffusion=10
3.Create a Cube,set layer=“a”,give a position let it show in screen
4.Create a Empty,set layer = “b”,add Post Process Layer,set Clear Flags = “Depth Only”,Culling Mask = “b”,Post Process - VolumeBlending.Layer = “b”
5.Create a 3D> PostProcessVolume(Named “B_Volume”),set layer=“b”,check IsGlobal=“true”,Weight=1, new a Profile, add “Bloom”,check: intensity + Soft=1 + Diffusion=10
6.Set intensity in “B_Volume” to 100
7.Why the BLOOM is binding my eyes ???

And,the higher Depth camera always bloom all the things it can see(even they are not in same layer).

That’s how post-processing works. Remember that it’s applied after the scene is rendered. At that time, there are no longer separate objects or layers- it’s just a flat image of pixels.

If you want to apply post processing to only certain objects, sometimes you can accomplish this by rendering just those objects first with post processing**,** then use a second camera to render the remaining objects afterwards. There are ways to amsk out certain parts of the frame too, but I haven’t done that before,so I don’t know the spefics of implementing that.

Thank you……
Looks like i need shader……
