Whenever you're ready for another all-in-one package,
please use a "Render branch" version of Blender!
I just tried this one: http://www.graphicall.org/builds/builds ... ow&id=1585
and the internal renderer is MUCH better than other recent ones;
not up there with LuxRender, but it does understand all the options.
(With your Sept 11th package, I can only get a few lighting options to work.)
So it would be stupendous if one could model
and test-render with a "Render branch" Blender,
and then pass all the render settings to Lux
(never mind if it takes a hundredfold longer).
