Spline Blend – Shape Morphing Plugin for 3ds Max

Spline Blend is a lightweight shape plugin for 3ds Max that lets you generate smooth, animated transitions between two splines—ideal for motion graphics workflows and surface modeling. Inspired by blend tools found in vector design software, it creates intermediate splines that interpolate between your selected shapes with customizable spacing and trajectory.

🔧 Key Features:

• Easing-Based Distribution: Choose from several easing functions to control how blend splines are spaced and shaped.
• Cross-Section Guidance: Use an optional guide spline to influence the trajectory of the blend, enabling intuitive morphing paths and loft-friendly geometry.
• Animation Support: Input splines can be animated—Spline Blend updates the blend dynamically at each frame, making it perfect for evolving motion graphics.
• Surface Creation: Easily generate lofted surfaces or smooth transitions between complex contours.
• Utility Tools: Includes a detachment feature with optional effects like incremental render thickness—great for stylized rendering or layered spline effects.

Whether you're crafting animated transitions or building loft-ready geometry, Spline Blend offers a simple yet versatile solution for spline-based workflows.
