Hey Alex,

So then what is the behavior you are looking for? I can see the difference in the images, and I see the increase in light levels in the second image. Can you please give me any more information you have on what your scene hierarchy looks like and any errors you are seeing? I would also like to point you in the direction of this post from a prior user. They were having similar issues and found a way to resolve it.

Please let us know what you find.

Hey Jason,

Yes I already stumbled on this past post and tried all the recommendations there with no luck. The behavior would be to use bloom on gameobjects and that it wouldn’t affect the camera feed.
Regarding the scene hierarchy, it’s just a directional light, a volume and the ARDK ARSceneManager. Hope this helps.

Hey Alex,

Have you tried adding any other managers or scripts to try and control the volume at all? I have a link to the documentation here that goes into detail on the URP and the integration of the ARRenderingManager into your scene. This may help you decipher how to get the bloom volume to function properly.
