Mosaic generator
Here is a test with my profile picture
A special thanks to my friend Killian Ekouma for letting me use his illustration on my work.

This Substance Designer graph turn pictures into a mosaic wall, with a fine control of the detail and chaos needed.
The technique developped in this material is a very nice way for getting natural and detail patterns, such as voronoi textures, from any bitmap you may have, wich can be declined to create tiles, rocks, glass, and many other materials.
