Rendering Technology in Agents of Mayhem
This talk, presented at GDC 2018, covers some of the main rendering technologies used on Volition’s ‘Agents of Mayhem’. The presentation includes Volition’s adaptation of Weighted Blended Order-Independent Transparency for use with additive as well as non-additive alpha. Also covered is Volition’s approach to tile-based deferred shading, which breaks shading into multiple shaders applied per tile based on feature sets to improve SIMD occupancy. Volition’s implementation of light-blockers, which extend standard light-clip planes to finite rectangles instead of only infinite planes is also be covered, as well as how these light-blockers can be applied to Light Propagation Volumes for GI to greatly reduce light leakage.
