利用者・トーク:Ton/Autodesk FBX EULA
How does this corelate with [1] ? it seems to me like you can do whatever you want with the software using FBX SDK as long as you credit Autodesk.
The page [2] also states: The FBX SDK is an easy-to-use C++ software development toolkit that allows developers to quickly add FBX support in their applications. This SDK can be freely used in both commercial software development as well as in-house software applications. FBX can be used in any kind of production environment including games development, film, video, broadcast, product and automotive design, architecture, visual simulation and medical visualization.
Also, the DLL version of FBX SDK library is available since 2011.3, so you can link to it on demand.
