Wow - DAZ3D still offers Carrara 8.5 Pro which I forgot I purchased years ago and still have installed on my computer. Never really gave Carrara a chance as I found Hexagon to be a much better 3D modeler.

Several years ago I became interested in Anim8or, but it seems the developer stopped working on it. It was also another FREE 3D modeling app.
