While the Megscans vegetation library is now worked on by multiple artists in multiple countries, at launch, I was the sole creator, later followed by Dan Woje in Australia.
I created the core of our atlas library, which has traveled from outside my mom's apartment into a vast array of game worlds.
Renders are early internal examples and tests, I have no idea who made them. The displayed atlases are of course just a small selection out of the many that were made.
