Small, open examples exploring features in Unreal Engine’s Procedural Content Generation system.
Feel free to explore, modify, and use it as a starting point for your own PCG experiments.

GPU Spline Sampler - UE 5.7+

Sampling splines on the GPU, scattering large numbers of points without putting pressure on the CPU

Mandala Generator - UE 5.7+

In this experiment, the tool builds mandala patterns using two approaches:

UV-Based: converts UV space into polar coordinates and samples patterns in the transformed space.

Point-Based: generates target points directly in polar space and uses them to copy and place mandala patterns.

GPU Texture Basic

In this experiment, I explore the new GPU Texture node introduced in Unreal Engine 5.6.

Book Row Stacker

Procedurally generating a row of books in Unreal Engine using PCG is fairly straightforward, but handling gaps and calculating lean angles was a fun challenge.
