Projection and Raycast are two of the most powerful nodes in Unreal’s PCG framework. They let you take floating, abstract points and snap them onto real geometry, making your procedural systems smarter and more believable.
In this episode, you’ll learn how to:
Use Projection to align points with landscapes or meshes
Use Raycast to detect surfaces and control point placement dynamically
Leverage hit results like normals and slopes for better object alignment
Combine both techniques to make environment-aware procedural systems
Whether you’re building cities, dungeons, or stylized worlds, Projection & Raycast are essential tools to make your PCG feel grounded.
