Maxwell Render™ is compatible with 3DsMax 2012 and Maya 2012! The full list of caompatible software and updated plugins you can find at they homepage listed at the end of this article. The Maxwell Render™ is a rendering engine based on the mathematical equations governing light transport, meaning that all elements, such as emitters, materials and cameras, are derived from physically accurate models.
