Spline Scatter PCG

SplineScatter distributes static mesh instances along a spline. Draw the path, pick your meshes, set the spacing; the graph handles sampling, mesh selection, ground snapping, and per-instance randomisation.

Built entirely with Unreal's native Procedural Content Generation framework. No Houdini, no Houdini Engine, no external application. Every parameter is an actor property, so each spline you place in the level is configured independently from the Details panel.

What it's for

Roadside vegetation, fence lines and posts, rock borders, debris trails, street furniture, or any run of props that should follow a drawn path rather than fill an area. Because mesh selection is driven by an array, a single spline can mix several meshes in a repeating sequence or in a randomised order.

Features

Even spacing along the spline

Density control with its own seed

Multiple meshes per spline, assigned in order or randomised

Vertical snapping up or down onto the landscape and onto meshes you nominate, with a filter for how landscape hits are treated

Per-instance random offset, rotation and scale ranges
