two minor issues:
A. a few books have their surfaces inverted. (meaning that their back-faces are shown instead of their front-faces)
B. the echo-rooms used for the infinity effect are somewhat misaligned with the main room.
Thanks for trying it out!
A. unfortunately some of the normals were messed up in the importation process. Wasn't able to find a fix sadly.
B. If you are referring to how the rooms curve, that was an intentional choice, it hides the fact that eventually it stops repeating for performance purposes.
This was mostly a kill some time project, so unfortunately it may not be the most polished.
