There is always a restriction on the use of lights and shadows in mobile games, due to limited computing ability. The art department called for Diablo Immortal to remove this restriction as adventurers travel through the wilderness. To this end, they have begun to reconstruct the rendering pipeline and various shadow rendering technologies based on the traits of mobile platforms.

In this talk, Hao Wu, the engine programmer, discusses how he can achieve efficient dynamic multiple lighting and shadows within memory and performance limits, and provide the highest possible compatibility.


Attendees will understand the key techniques of light and shadow rendering on mobile devices and how to solve overheating issues on mobile.

Intended Audience

This is for engine programmers, graphics programmers, mobile game developers. Understanding of basic lighting and shadowing might help in grasping full context but it's not required.
