Splines Growth is a Blender add-on that generates organic spline-based growth animations directly on mesh surfaces. It is designed for artists, animators, and motion designers who want to quickly create growing vines, roots, abstract energy effects, or procedural curve animations without relying on Geometry Nodes.

The add-on is lightweight, intuitive, and fully integrated into Blender’s 3D Viewport Sidebar, making it beginner-friendly while still powerful for advanced users.
