At GTC Digital KeokeN describes the company’s experience using ray tracing to enable new graphical realism in Deliver Us The Moon, with UE4 and NVIDIA’s RTX technology.
The game is a Sci-Fi thriller set in an apocalyptic near-future where Earth’s natural resources are depleted. In the talk, the team describes what optimizations they did, why they did them, and reveal more in-depth details about how ray tracing works in UE4.
“Conventional graphics content is optimized for rasterization, but not for real time ray tracing. Simply flipping the ray tracing switch will most likely result in a poor user experience,” the team said. “It is imperative to evaluate the content for its ray tracing performance and apply necessary adjustments to achieve the best possible result.”
The adjustments described in the talk consist of material and lighting tweaks, balancing of UE4 ray tracing features and sometimes even geometry changes. The talk also describes how developers can identify and fix your ray tracing performance issues.
