In this session recorded at Unreal Fest Stockholm, Croteam builds on last year’s Technical Content Grimoire talk and showcases some of the ways they optimized materials, textures, and geometry for ‘The Talos Principle: Reawakened’.

Croteam explores how to go about refactoring complex materials that are actively in use; lessons on the use of Runtime Virtual Textures (RVTs) on Landscapes; and how to count Shader Resource View (SRVs) for a particular material, along with how Nanite and Virtual Textures add to their number.

They go on to look at what type of Nanite Foliage is the most performant in the current version of Unreal Engine and provide hints on how to optimize it using Houdini.

There’s also a dive into how they utilized AI and Houdini for remastering old geometry and making it high fidelity for ‘The Talos Principle: Reawakened’, as well as how to unify a foliage system under the procedural content generation (PCG) framework with various tools.

Finally, the team explores which custom tools are useful if your game has a lot of third-party assets and workflows, and how to make them work for your project.
