I would like to introduce you to the Simple Instanced Spline Mesh plugin.

The plugin provides a simple, lightweight, and robust tool for building Hierarchical Instanced of Static Meshes using splines.

It was built with level design in mind, to make designers' life easier, and iterations faster.

It offers a variety of tools related to meshes placed using spline.



I am happy to see what you've made with this. If you encounter any errors or crashes, feel free to contact me, I will do what I can to make it work as well as possible.

Technical Details


  • Multiple meshes - you can set multiple different meshes that will automatically align on the spline. The meshes are aligned using their bounds, not the pivot, which means that if you have a mesh, that has some bad pivot, the tool will still align it in a smart way!
  • First and Last meshes - you can set up special meshes at the beginning or end of the spline, which allows you to control exactly how your fences or walls begin or end.
  • Mesh randomizing - with multiple meshes selected, you can make them appear randomly so that your fences, walls, or even towns are extremely simple to randomize to make them look more natural.
  • Ground alignment - the tool allows aligning meshes to the ground using their bounds, which is much more accurate and good-looking than using pivot casting. Also, the ground alignment can be applied to each mesh individually.
  • Asynchronous calculations - calculations are by default performed on a separate thread, which allows creating very, very long splines with thousands of meshes without freezing your computer, which improves the level design speed and makes it more comfortable.

Important/Additional Notes: Currently ground alignment work for Landscape only, but it's a work in progress, and we are planning on adding support alignment to other surfaces too.
