Spline-Objects-Tool

A tool for Unreal Engine 4 which allows to spawn Instanced Meshes / Actors / Decals along a spline in the editor. The spline's points can snap to the environment and the objects can be aligned to the surface.

How to install

Create a Plugins folder into your project and paste the folder SplineObjects which is located into ToExport/Plugins/.

Now you can create some Spline Objects Actors.
