Input System not detecting button hover on UI Toolkit element. URP vs HDRP

Unity Engine

Hey what’s up.

I’ve got two identical scenes set up, except one is in URP and the other is in HDRP.

The UI Toolkit button on the screen detects ‘on hover’ properly in URP, but the same setup is not detecting the hover in HDRP. I’ve done all the configuration steps properly in both…

Is there some kind of HDRP reason this system won’t work? It seems to be arbitrarily working on one, but not the other.

UPDATE: I tried a third scene, using 3D UPR as well… Everything works fine in that too. It seems to be something with HDRP configuration. URP Camera components have an option for changing the Render type between Base and Overlay… This option does not exist in the HDRP Camera components.

Ok… The issue emerged in 3D URP as well…

For some reason, when I change the background color of the element through UI Toolkit, it breaks the responsiveness… If I don’t change the background color, the responsiveness stays… Input System may be working just fine, I will move this line of questioning over to the UI Toolkit forum.
