I just attended the 3ds Max Advanced Modeling (live from Spine3D in USA) webinar and it was very good and informative.

3DATS, CGarchitect & Spine 3D have come together to form CGschool.

CGschool provides high quality training solutions for design visualization professionals. Our products and services include customized training, 3D design consultation, training books and DVDs, as well as some of the best content available in the visualization industry.
