PCG Point Sampling – Surface, Spline, Texture & Volume Explained
In this episode, we explore the power of point sampling in Unreal Engine's PCG framework — one of the most creative and flexible parts of procedural generation.
Learn how to generate points based on existing geometry or data, using:
Surface Sampler – place points on meshes or landscapes
Spline Sampler – generate points along curves or paths
Texture Sampler – use grayscale/RGB images as density masks
Volume Sampler – fill 3D spaces with points for fog, effects, or ambient logic
Each sampler gives you a different level of artistic control and logic-driven placement, letting you spawn smarter and build faster.
