While Painter has revolutionized 3D painting, getting all the different textures prepared and "baked" for their asset is still a necessary step before and after getting to the actual painting phase. With RTX and hardware accelerated ray tracing now integrated in Painter, times for baking are dramatically reduced, allowing to quickly iterate between modeling and painting phases, many more design iterations and leaving room for actual artistic creativity instead of waiting for long compute times. Nikie will share her first experience with RTX baking in Substance Painter on actual assets and how it impacts her creative workflow.

It upgrades standard static light probes to both fix light leaks and accelerate them for dynamic run-time ray tracing on any recent GPU. This streamlines art workflow, increases visual fidelity, and lifts lighting restrictions on gameplay. We describe this probe technique along with new implementation details that give a 2x performance increase and heightened image quality over previous versions. We also show how to accelerate ray traced reflections and full GPU path tracing using the same probe data structure, and discuss the road map for this technology. (related work, and more)
