THE TREACHERY OF RENDERS: THIS IS NOT RENÉ MAGRITTE
Pure Blender 2.79, Cycles, only procedural textures.
Inspired primarily by René Magritte’s “The Treachery of Images” (also more popularly known as his “This is not a pipe” work):
There are also visual allusions to other themes Magritte frequented.
Technical note: the image in the center is a reflection of the scene (with modified geometry and spatial placement to reflect only certain elements and to make the sky appear as an ocean).
