What if you could visually describe the lighting/weather/landscape you want, and have the machine replicate it for you inside a game engine? You can spend hours tweaking dials in a procedural system to get it to look 'just right.' Think weather, lighting, or art direction that mirrors a real world or artistic reference. But what if you want to bring other aspects of reality into 3D tools like Unreal?
3D scanning is like copy/paste for the real world - capture something once and reframe it infinitely in post-production.
