This is good. Set up Blender with the same aspect ratio as I’m using in Vue (2.35:1). Rendered the cube in Blender, noted camera transform, exported cube as Collada. Imported cube into Vue, set camera transform as same as in Blender, same focal length, set up camera projection material for the cube (diffuse and alpha in PS) and voila, it works. Increases the interoperability of Blender/Vue.
