URP materials issue

[tom]

I've been playing around with this asset a bit.

I'm using URP in my project, and while everything seems to work normally in edit, as soon as I press play, this happens:

The inspector for the book also reverts to the default values.

Is it incompatible with URP or am I doing something wrong? The built-in books seem to work without problems, even though I've auto-converted their materials to URP as well.

My materials are using RenderTextures, but I've tried with ordinary materials and got the same result. I have no idea what I could be doing wrong. Any pointers?

I've noticed an uptick in this question in my emails, so I decided to make a FAQ for it. Check it out here

Brilliant. Simply unpacking the prefab works.
