Rolling Shore Waves in 2XKO's Scuttler's Strand - 3D Procedural Vertex Shader Techniques

Learn to create realistic rolling shore waves using advanced vertex shader techniques in this conference talk from Unreal Fest Bali 2025. Discover how Riot Games' Mathieu Dufresne developed the custom 3D procedural displacement system that powers the dynamic shore wave effects in 2XKO's Scuttler's Strand stage background. Master the implementation of a fully shader-based approach that creates authentic barrel-rolling surf waves without traditional 2D displacement methods or complex simulations. Explore the mathematical foundations using simple functions like sine waves, modulos, frac, and lerps to build sophisticated wave behaviors that never repeat patterns and run entirely at runtime. Break down complex shader development into manageable components and learn best practices for organizing work within Unreal Engine's Material Graph to maintain clean, readable code. Understand how to stack multiple simple techniques to achieve complex visual results while keeping the underlying mathematics accessible and performance-efficient.
