Epic Games' Tools Programmer Adrien Logut released a tutorial video covering GPU-based Procedural Content Generation (PCG) in Unreal Engine 5.6. The tutorial demonstrates how to enable GPU execution on supported nodes, create custom HLSL nodes for point generation, and sample landscapes directly on the GPU. This feature, showcased in The Witcher 4 tech demo, allows runtime foliage generation on GPU and has been available since UE 5.5 with significant optimizations in 5.6. The tutorial includes project files and covers both advantages and limitations of GPU-driven workflows.
