Just lately Escher ghosted through this forum, and left - again - a lasting impression:
- stairs and other hard stuff: TS
- Plants: Zbrush (some are NURBS out of TS, but I like those ZBrush-veggies best)
- Stick figures: Poser (sorry for that)
- assembled, rendered in Vue 4.2
What it is? Just don’t ask me! 
But, there is a small part of Escher there (way to the left), and there are those O2-emitting plants (right side).
While Deevee (from what I’ve seen) always tends to have some chrystal clear pics as a result of working with Vue, mine are generally well fogged.
In the interim, I will soldier on with 4.2. I understand that they are working on an upgrade for 4.2 also, so we will see.
