I created this for BlenderArtists.org Weekend Challenge 784.
"Under the guardrail" was the theme.
The title of this piece is a play on words - the phrase "scrubbed launch" (cancelled launch).
Everything here was created, rendered, and finalized all within Blender (2.79, Cycles).
Only procedural textures used. No smoke sim either: those are complex procedural textures as well.
