le book has limited support
As le book is now free for personal and commercial use, I can only offer a somewhat limited amount of support. Head over to the Telegram support group to find help.
Current version
le book 0.12.0-0000


Cinema 4D R18 to R20: You need at least Cinema 4D R18, “studio” or “student”.
Cinema 4D R21: There is only one version, so you don’t have to worry about that.
With Cinema 4D open, you will find the installed and registered version under “Help” -> “Personalize” or “Help” -> “About”.
This is mostly due to missing OpenGL capabilities of the graphics card and the faulty and often outdated OpenGL stack in Mac OS X. OpenGL then outsources certain operations on the CPU, resulting in a stuttering mouse cursor. I recommend to set the editor quality to low (README / register / presets -> Advanced -> Editor quality).
A known Bug in Cinema 4D R16.011 (Build RB107079) stops the inner book from being displayed correctly. Update Cinema 4D.

If you have any questions or problems related to the le book asset, please first visit the documentation and make sure you are using the latest version of le book and Cinema 4D.
