    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

MagicSpline is a plugin allowing the creation SplineMeshActor in your levels to generate and edit meshes following a spline mesh (static meshes or spline meshes with deformation). It’s a powerful level design tool that can be used in many ways (walls, roads, pipes, chains, fences, blocking volumes, etc.) in an optimized way.

it's an optimized C++ plugin but you don't need to know programming to use it. Like in the video in the description, you just have to create a new blueprint based on the class SME_SplineMeshActor. Then you can add this blueprint actor to your levels and just edit the settings in the details panel. The plugin will be automatically installed on your engine.

If you know C++ and would like to add some extra functionality to this plugin, it's also possible as the source code is provided.

Technical Details

Main Features:

  • Layers (group of segments and settings allowing multiple meshes attached to the same spline)
  • Collisions (enabling collisions on spline mesh is possible but very inefficient but you can create a separate layer to handle collisions with invisible static meshes in an efficient way)
  • Offsets
  • Twist (curve the meshes to create chains, screws, etc...)
  • Overrides Segments (use different settings for specific segments of the spline)
  • Imperfections
  • Branches
  • Physics (with UE5 only)
  • Blocking volumes (easy way to create a chain of blocking volumes)
  • Gaps
  • Mesh distribution modes (by mesh length, by segment count, Per spline points, hybrid)
  • Runtime animations (set the actor to Movable and call the function "UpdateSplineAtRuntime" from BP or C++ )

It's possible to bake the all actors into a StaticMesh (Main menu > Actors > Merge Actors).

You can add multiple meshes into the same layer to generate randomness, each segment of the spline will select a mesh randomly from the list of meshes.

Module: "SplineMeshEditor" [Runtime]
