If you only need to view the scene and never save it, you can install the Ornatrix demo version.
But if you save the scene with the demo version, all Ornatrix data in the scene will be reset to default values.
We'll investigate again the possibility to check the license only on editing.
The problem with this in Maya (compared to 3dsMax) is that GUI is defined in scripts, and we can't place the license checks there, as they can be easily removed.
