I have thought of another question... does Enderal support or exclude "triple monitor" play?
The reason I ask is that in vanilla Skyrim, a small number of people play the game using a triple monitor setup, though there are a few issues. When those people use the new meshes in Book Covers Skyrim, the model and texture of the book appears as expected on the middle monitor but the pages are totally blank. After extensive investigation, there was nothing I could do about this. It was almost as though the model appeared in the middle but the page was being drawn somewhere else outside the display window. I believe it may be something to do with the Havok animation of the book opening and this is a compiled module we have no control over.
It didn't matter in vanilla Skyrim because people with three monitors could choose to play without Book Covers Skyrim but if the new book covers are incorporated inside Enderal (rather than being a separate mod) then any triple-monitor users would be locked out.
It does not affect single monitor users in any way.
