Improving Direct Lighting Material Occlusion - Part 1

Piqué fabric with micro-occlusion on the top, and micro-shadowing at the bottom. Both are using the same micro-occlusion map. Geometry virtualization and displacement systems like Nanite has allowed us to substantially increase the geometry resolution. But when it comes to representing small details like cavities, cracks, and creases, those types of solutions are too expensive to be used…
