I've used the same background just rendered at a
different angle and light, not too sure if they matchup
correctly, but are close.

I quite like the tool for "easy extras" in a scene.
I might just add some plants in the "Mad ScienceLab"
have some "moss" on the walls; weeds growing through
the cracks in the floor; ivy in the corner...?

hopefully theres an image attached,
I'm still getting use to attaching and posting.
hopefully it's not too large
