Opus3D stress test

Decided I better test that Opus can cope with complex models sooner rather than later so found a free sonic OBJ model, loaded it into Milkshape and exported it using the Opus exporter I quickly threw together.

I'm actually very pleased with the performance with a complex model like this. Interface runs smoothly, selections and modifications happen at the same sort of speed as they were with the cube. A good experiment to pump up my motivation a little.
