The practical tutorial provides a step-by-step guide to simplifying SVOGI system’s many settings down to the essential parameters that you need to fine-tune ambient lighting for both interiors and exteriors. By the end of the tutorial you will be able to implement lighting that behaves very similar to how it does in real life.
In the video, Brian recommends best practices which are proven in production, and discuss how the Crytek development team met complex lighting challenges Hunt: Showdown.
