ARFoundation in HDRP on iOS - Camera image not showing

Unity Engine

Hello,

I’m aware that mobile apps are not supported in HDRP and that ARFoundation only supports LWRP/URP.

But we have a running iOS app in HDRP (after enabling it in the package) and now we are trying to use ARFoundation with it. It seems to work (I can see objects in the tracked space) but the background camera image is not showing.

Is there any way how we can achieve this in hdrp?

Thanks!

The whole AR Foundation rendering chain is not built for HDRP. In URP you need to add the AR camera render feature to the urp renderer. You probably need to develop/port that

DevDunk is correct here. You would need to implement your own render feature to support ARCameraBackground in HDRP. We do not recommend that users use HDRP with AR for performance reasons, thus we have not implemented this.

Okay thanks for the replies. We wouldn’t publish the app… It would be just for demo purposes.on a new iPad and the tracking performance looked fine.
Now we changed already to URP.

I don´t suppose you got anywhere with this? I’d love to mess around with HDRP AR on a new iPad

How about an m2 iPad / Vision Pro? Presumably they’d have enough grunt… What would be involved in making an HDRP Camera render feature, and is it something you’d ever consider doing officially now that we are getting access to higher performance mobile devices?

Possibly!
