Character does not matter, any character will do.

 

Went to bed, came back. Yeah, I know, but when I hit a knot?

In the first test the floor and roof are horizontal, and the infinite light should not touch them.

Reflections from the side panels also come back to the infinite at an angle due to the canted walls .
Except, balls, they start reflections to all directions. And are glowing in all directions (ambient 5).
Roof and floor should only react to reflections.

In the second test with the tilted roof.
Same thing, but now the floor is lit by the roof reflection also.
(notice the body shadow around the feet.) Nice!
Infinite light bounces off the roof, to the floor, making it "better"? that "solves" a first mystery.

 

View angle may be important but this light from the roof does the job.

Still tinkering about the red - yellow imperfections on the roof. . . . .  
The Blue ball, the white between the knees, the chest. . . 

And the "hard" rendering of the roof and floor when no infinite light hits them?

They are too "brutal" to be caused by a ball.....

 

Just hope SM follows this, post;
i posted a ticket, but is is quite hard to explain all this in words. And all the evolutions. . .

PS, sorry, for some word choices, but English is not my first language.

 

On this, I am gonna try to get some sleep……. 3AM now. . .
Have a nice evening, i'll great ya all in the morning. ;-)
