Cool soft... A very complete and professional 3D modeler and renderer. The 3D capability of the software is quite impressive (I've never seen a free 3D modeling software with so many features), but the GUI is also ruling GUI since it allows real fast creation and rendering of models. What rules according to me :
1) newbie accessibility :
- A real "click and go" installer, which keeps you aware of what it does, and lets you change installation directory and option (could this installer one go open-source ?)
- A "tip of the day" which drives you through the first steps.
2) non-invasivity and intuitivness : One window, with different tools sub-windows inside this window (texture selection, shape adjustment, ..): you don't lose 60% of your time looking for hidden dialog boxes and windows, since the GUI arranges everything in a comfortable manner. You can close or reduce these tools windows, and of course none of them is modal (my worst nightmare is modal dialog boxes)
3) speed : Moonlight provides you with a series of shortcuts "a la photoshop", which enable fast moving, scaling, selection, rotation, ...
4) portability : The GUI is 100% Open-GL.
