Explore the technical intricacies of creating "Alpha Point," a UE5 demo showcased at GDC 2021, designed to evaluate Unreal Engine 5 on Xbox Series X/S. Delve into The Coalition team's insights on testing Nanite assets in Lumen-driven lighting scenarios and their assessment of UE5's performance in Xbox Series X and S production environments. Learn about high polygon modeling challenges, material setup techniques, texture generation, and the implementation of paintable volume fog. Discover the team's experiences with Lumen performance, virtual shadow maps, and Nanite performance optimization. Gain valuable knowledge on custom VEX buffer usage, performance UI widgets, and specific considerations for Xbox Series S. Examine character statistics and performance metrics, and absorb key learnings from the Alpha Point project in this comprehensive 59-minute presentation by Kate Rayner and Colin Penty from The Coalition.
