Topic: Programming

Format: Session

Vault Recording: Video

Audience Level: Advanced

This advanced technical talk takes a deep dive into Nanite's novel GPU driven material pipeline.

A high-level overview is presented, detailing all of the core components and explaining how they fit into the overall design.

This talk also covers low-level technical details, including how artist-authored materials drive the rasterizer, how final shading is evaluated, an innovative variable rate shading technique, and some challenges of GPU driven rendering.

Additionally, this talk discusses several learnings and optimizations that were discovered during the development of these components.


Although several advanced technical talks have been given on Nanite, the GPU driven material pipeline has only been briefly mentioned. By attending this talk, the audience will acquire a deep, low-level understanding of how Nanite evaluates its fully GPU driven materials for both programmable rasterization and final shading.

Intended Audience

Attendees should already be familiar with the previously presented technical details behind Nanite, Unreal Engine 5's virtualized geometry system.
