Splines Growth is a Blender addon that allows you to generate and animate organic spline structures growing across any mesh surface. Perfect for visual effects, abstract motion graphics, or nature-inspired growth systems like vines, roots, or sci-fi energy paths.

✨ Features:

• Mesh-Based Growth: Splines grow across the surface of your selected mesh.

• Randomized Paths: Each spline avoids exact duplication for more natural results.

• Full Animation Control: Define start and end frames, growth speed, and even reverse growth.

• Curvature Offset: Add natural variation with random curvature distortion.

• Variable Thickness: Randomized bevel radius for organic results.

• Built-In Emission Shader: Splines automatically come with an emission material, ready for rendering.

• Batch Delete: One-click cleanup with the Delete All Splines button.

• Customizable Splines Count: Generate from a single spline to hundreds.

🎬 Use Cases:

• Creeping vines, roots, or ivy-like structures.

• Energy growth effects in sci-fi and horror projects.

• Abstract generative art.

• Organic particle flow simulations.

• Procedural-looking motion graphics without geometry nodes.

📦 Included:

• The Splines Growth Addon (Blender 4.4+).

• Easy-to-use panel in the 3D Viewport Sidebar.

• GPL-licensed script with full source code.
