This work was featured on Unreal Engine's GDC sizzle video as "Photogrammetry", but I've only just now found out where it came from. The creator, Rense de Boer, goes by the consistent online branding of Art by Rens. He worked at DICE from 2011 through 2014, working on the Battlefield franchise, and now he seems to be doing his own thing.

The environment work is stunning. The snow, slightly thawed and refrozen, covers the rocks and leaves in a way that looks absolutely real. Some of the rocks look partially moss-covered, with the plant seemingly breaking it down, and coming up through the cracks. There's only so many ways that I can describe it, but it's definitely worth a look. He targets four Titan-class video cards, but he's aiming for 4K.

He hasn't announced any product yet, so we're not really sure why he's doing it. He did receive a grant from Epic Games, though. I'm not sure exactly how much, just that $500,000 USD was split 30 ways, but not uniformly (some received more than others).
