1.  In HDRShop, use Panoramic Transform to convert an HDRI light probe 
to Latitude/Longitude if it isn't already in that projection.
2.  Save as Low Dynamic Range image.
3.  Create a sphere in Moray.
4.  Scale the sphere so it encloses the entire scene.
5.  Create an image map texture using the LDRI image with ambient value 
of 1, apply that to the sphere.
6.  In Scene:Settings:Global Settings, set Ambient Light to 1.
7.  In Scene:Settings:Radiosity, set count to a sufficiently high value, 
and error bound to a low value, optionally setting grey threshold to 0 
if you want the colours from the light probe.
8.  Render.
