I just released
CopperCube 5.3, it includes quite some new features such as fog rendering, much better Blender .blend import, experimental FBX support, WebGL and Android improvements and more.
The unusual thing is that I am
giving away CopperCube Basic edition for a 50% discount now. Crazy, I know, it is a bit of an experiment.
A detailed list of the changes in version 5.3
can be found here. It is a pretty nice list, and I'm quite happy with it.
