Don't worry...she has done renders from within the shpere   & she "gets  it" ( search out her old Stonehenge product from 2 years ago... all built around a custom environment map using the old hi res sphere.  putting a "world" around the objects has been something she streesed to users for many years, but not everyone wants to do it that way, so she shows other ways to intergrate 2d & 3d together c'est la vie )

Trying it out now, I see the preview, but it's a weird workaround... Thank you though. rendering out a test to see whats up with the normals reversed.

Has anyone compared the uv mapping of say a Vue, 3dsmax or LW environment vs the EF primative, or are the "big boys" simply using node math to represent the spherical environment when the users invokes global lighting?
