Relto's celestial bodies (sun and moon(s)?) are just flat planes, in much the same way you describe, though I believe they're not sprites =)
Note: There is not a 100% 1:1 feature parity with blender and Uru, so you might not be able to use every little feature of blender in Uru. I believe the pyprp2 devs are working on using constraints to handle sprites, though, as they're mostly similar.
But afaik, this isn't anywhere near ready yet, and from what I understand, there's not much development being done on pyprp2 right now.
