Bookshelf prefab pack
Made by The Giblets of Jesus
The pack contains 1 model, a .vmf for all the brush work and 7 textures. The prop version of the shelves is basically just the brush version, only converted to a model using propper. I also included the brush version of the shelves so that they can be re-sized or possibly used in 3D skyboxes, should anybody wish to do so.
As you can probably tell by the screenshots, I used the models made by valve to create my own, brush versions of the books for the bookshelves to be used far away from the player, saving resources as a bunch of models wouldn't have to be rendered, only a few brushes. This means that the brush version of the shelves and books can also be used for CS:S, but not for all source games since I used a wood texture used in CS:S.
If you have any trouble getting this to work, just leave a comment and I'll do my best to get back to you about it as soon as possible.
If you do decide to use this prefab in one of your maps, I'd like to be credited as appropriate and while not required, it'd be nice to told so I could see how people have used it.
