Thanks to Legaz's great Blender/QTVR Tutorial, I was able to make my first QTVR movie using Blender. I wanted to create a useful reference for future QTVR movies in Blender, so I created a scene with a camera inside a cube and reference numbers in front of each wall. The camera rotates from frames 1-6 to face walls 1-6, thereby making it easy to render the necessary images for MakeCubic to create the VR movie. You can download the blender library file and reference movie here or here. Then simply import the Camera object from the .blend file (Objects->Camera) into your landscape or detailed interior scene, render frames 1-6, and feed them to MakeCubic. Works great!
