As a high-cost, high-quality graphics algorithm, ray tracing has always been a guarantee of excellent image quality on the PC side. Today, this GPU hardware technology has been widely implemented on mobile hardwares, which provides new tools for mobile game developers, but also poses new challenges. In our actual project based on UE4.27, we used hardware ray tracing solutions to achieve shadows and ambient occlusion effects. Due to the heating problem and performance limitations of the mobile terminal, we have adopted a variety of methods to optimize from API calls, acceleration structure construction, and light emitters in shaders. The performance effect is leading and has reached a practical level.
