Hey Gary, If I'm understanding yo correctly, one way you could abstract out this rotation to make it a bit more clear is to project the cubic environment through a sixpack (cubic camera) setup and then you can just parent the setup to an Axis to do the master rotation.
Check this nice tutorial Frank R did a while back for some pointers on a latlong>cubic>projection workflow. http://www.youtube.com/watch?v=Uq0kcUJ_XA8 On 26 March 2013 11:03, Gary Jaeger <[email protected]> wrote: > Can someone give me a sanity check on what to expect with the > SphericalTransform node?
