MobileHDR doesn't render materials from PAK Files (required by Mobile Deferred Renderer)

So I have DLC in my game. I would like to use Deferred Mobile renderer because it looks great, however when I use it, my DLC maps have no materials loaded, all DefaultWorldGridMaterials. If I am using Forward Renderer, it appears.

I am doing both a full rebuild on the app and the DLC when testing both.

I am testing on a Samsung Galaxy S23 Ultra and Meta Quest 3, with the same result on both. I am using a source build of 5.4.4.

Any advice would be great. Thank you.

I believe it has to do with MobileHDR. On Forward Renderer, if Mobile HDR is on, the result is the same.

If Mobile HDR is off, it works. Deferred Renderer forces use of Mobile HDR, so that is truly the culprit it seems, not Deferred Renderer
