On Gears 5 one of the big new technologies that came online for us was volumetric fog. This created many new possibilities but also some complex challenges such as how to create break up and localize control over density without incurring a heavy memory or performance overhead. Through our development of dynamic '2.5D' volumetric textures we were able to deliver a flowing poison gas time pressure mechanic for our Escape game mode and other volumetric effects very cheaply. This talk will go over our approach to authoring Volume Fog manipulation tools, managing prebaked and dynamic fog systems, and rendering the volume fog efficiently using UE4.
Attendees will get an insight into how they can cheaply create complex dynamic volumetric imagery through simple shader tricks and efficient texture usage.
Anyone with an interest in how best to leverage volumetric shaders, raymarching or general shader tricks will get something out of this talk.
