Thanks to CarraraCafe, Carrara developers can again have access to the Carrara SDK! 🙂

In the turbulent transition to the new forum and new store at DAZ3D, the SDK
(Software Development Kit) for Carrara 8 went MIA (Missing in Action).
While things get sorted out at DAZ3D.com, those interested in making
new plugins for Carrara can find the SDK right here at CarraraCafe in
the Downloads and Utilities section.

The SDK includes 2 manuals covering over 250 pages and more than 20 examples.
