Applying an image effect to just one camera

I have two cameras in my scene, one for almost everything, and another for a single layer which will be part of the HUD.

For the HUD I want to add the bloom effect, so I did on that camera, but despite that camera's culling mask only showing the one layer which I applied to just a couple of GameObjects, everything has a bloom applied.

This seems like odd behaviour to me and so how do I go about just having a bloom on the HUD elements?

 

How is your HUD camera configured? The first idea that jumps out to me is that you're passing a render texture from one to the other, so the whole thing is being passed to the image effect instead of just the HUD elements.

 

Normal Camera:
Clear flags - Skybox
Culling Mask - Everything apart from the HUD
Projection - Perspective
FoV - 60
Clippin - Near: 0.3, Far: 1000
Viewport - X: 0, Y: 0, W: 1, H: 1
Depth - 0
Target Texture - None
Occlusion Culling - Yes
HDR - No

HUD Camera:
Clear flags - Depth Only
Culling Mask - Only the HUD
Projection - Perspective
FoV - 60
Clippin - Near: 0.3, Far: 500
Viewport - X: 0, Y: 0, W: 1, H: 1
Depth - 1
Target Texture - None
Occlusion Culling - Yes
HDR - No

 

Sorry for the necro, but have you solved this @Dudledok ?
I'm facing the same problem. I have 3 cameras, one for almost everything and two for backgrounds (in a 2D game).
I would like to apply bloom to the camera in the middle, but it applies to the lowest as well.

 

Does it apply to just two of the three? If so try and find the difference between those two and the third. No I didn't solve it.

 

If I add bloom to the second camera, it applies to second and first (depth 0 and 1).
Since the second camera renders stars I've gone around it, by switching it with the depth 0 camera... Sort of hard to describe it.

I of course caused many other problems, but I'll hopefully solve those.

 

Sorry for necroing too, i've got the same problem, any ideas on this one? Should i fiddle around with camera depths?

Edit: Nope, that doesn't work too.
