I worked in 3D Studio Max to do various animations when I worked at Haptics in 1995. A stand-out project was doing part of an animation for a music video for George Michael.
My first introduction to Online 3D Modeling was Active Worlds, round about 2003. In 2006 I discovered Second Life. Later when Second Life evolved to sculpties and meshes, I graduated to various Software applications, like Blender, Max, ZBrush and Maya.
