Okay, turned off shadow casting and receiving and self shadows on the orb. The pic below the top one is the result - but is it better than the one above it or not?

I'm not really sure, I'm not sure that the suddenly redder floor is so much better - I think I prefered the bluer floor.  And both the top one and the bottom one of these two pics took almost the exact same time - one and a half hours.

Where do I go from here?

I can live with one and a half hours but is it getting better or not?

Oh and although the orb sheds light, there is the light that the warehouse/engineroom/storeroom whatever this place is, had before the orb got there.  So the orb is not the only source of light in here.

So, improvements?  Yes?  No? Maybe?
