On this occasion, we will discuss this material presented by Obsidian Entertainment's Lead Graphics Engineer, Matt Campbell, during Unreal Fest 2025 in Orlando. It is a detailed technical retrospective on the GPU optimization of the action role-playing video game Avowed. The presentation highlights the custom modifications they implemented, such as the use of ray tracing for local lights and strategies to reduce the overhead of Nanite and VSM, with the ultimate goal of achieving stable performance and ambitious visual targets in a semi-open world.

Today, we will talk about an article written by Arseny Kapoulkine (creator of MeshOptimizer) regarding the process he followed to optimize the processing pipeline for the geometry of NVIDIA's Zorah scene, which has billions of triangles and weighs up to 32 GB. In the article, he discusses the challenges of implementing a hierarchical LOD by clusters, similar to Unreal Engine's Nanite, managing to reduce processing times from half an hour to just two and a half minutes.Read full article:

Today we will talk about this paper that was presented at EUROGRAPHICS 2022, by Basile Fraboni, Antoine Webanck, Nicolas Bonneel, and Jean-Claude Iehl, from INSA Lyon and Univ Lyon. In it, they propose a new method for efficiently rendering volumetric effects like clouds or smoke in cases where sequences of frames (or multiple camera views) are needed, in which they reuse light paths across different frames, and propose a Multiple Weighted Importance Sampling estimator to handle these contributions from the shared paths.Read full paper:

In this session, we will analyze a paper by Jaime Postmouth, Peter Kuts, and Stephen Hill, in which they present a new bidirectional reflectance distribution function (BRDF) based on Oren–Nayar, but energy-preserving. They also introduce a sophisticated importance sampling scheme called CLTC, which drastically reduces variance in ray tracing.

Today we’ll be talking about the presentation given by Peter Shirley from Activision at High Performance Graphics 2025. In it, he discussed the use of exponential Spherical Harmonics to replace the Split-Sum method, by re-encoding the environment map with a view-dependent factorization. This approach removes the need for a multi-level cube map, saving disk space and making the process noticeably faster — though, with some limitations
