In case it's of use... I've been making some spherical panoramas of cloudscapes / landscapes using Vue.

They work in Poser, using Baggingsbill's free 360 degree Environment Sphere.

There are 2000 pixel wide versions in my gallery...

...or 4000 pixel wide at the following link (in .hdr file format):

I'm working on some 10,000 pixel wide ones... and plan to do some aerial perspectives in due course... probably at cloud height, looking down to fields below... although it may be a while before I fit that in.

The current ones are all from a ground viewpoint... but if you scale up the envsphere to 1000%, along with upping your camera's yon value to the max, they should still look okay from a viewpoint quite high up off the Poser ground plane...
