Character Studio

Character Studio is a set of tools within Autodesk’s 3DS Max. It was originally sold separately as a separate add-on product (complete with its own separate packaging, installation media, manual, etc.), then included on the 3ds max installation media in trial version form that could be fully activated by paying extra for a separate license in subsequent versions, and is now included in fully functional form at no extra cost with more recent versions starting with 3DS Max 7 and including all versions numbered by year.
