High definition render pipeline, shader graph, GPU-based progressive lightmapper
summary
Demonstration shows the HD Render Pipeline with Shader Graph, photogrammetry assets and Quixel Megascans powering the Book of the Dead level running at 30 FPS on PlayStation 4 Pro. Realtime features include area lights (cost ≈2× a spotlight without shadows), volumes, decals, tessellation/displacement, layered materials, subsurface scattering (including a Disney Burley option) and multiple-scattering specular. The GPU progressive lightmapper is a GPU path tracer that bakes millions of texels using hundreds of millions to billions of rays in seconds for rapid iteration.
