respline 1.3
Respline is a powerful Cinema 4D spline toolset plugin that adds ten new generators and modifiers to your workflow. These tools allow you to create, modify, and animate splines in ways that are not possible with Cinema 4D’s native spline tools alone.
Each Respline object is fully procedural, interactive, and animatable, allowing you to use them individually or chain them together to build complex spline-based systems. From motion graphics to technical modeling, Respline opens up an entirely new way of working with splines in Cinema 4D.
Tested and working in Cinema 4D R23 - 2026
Respline Core Features
- 10 amazing tools to create, modify, and animate splines
- Chain tools together for interesting combinations
- Each generator automatically converts polygons into splines
- Interactive and animatable controls
- Fast, flexible, easy to use!
01. Spline Mesher
The Spline Mesher converts any spline into polygonal geometry using a variety of cross-sectional shapes such as circle, square, rope, and chain. This makes it easy to turn abstract splines into render-ready geometry without relying on Sweep objects.
Additional shapes can be added in future versions, making this a flexible foundation tool for spline-based modeling.
02. Slice Generator
The Slice Generator cuts an object into multiple splines along its surface. These splines can then be manipulated using intuitive controls to create layered, segmented, or animated effects.
This tool is especially useful for stylized motion graphics, data-driven visuals, and procedural reveals.
03. Edge Splines
Edge Splines converts polygon edges into parametric splines. You can choose how edges are generated using three different modes: All Edges, Phong Tag, Override Phong Tag
This allows for precise control over which edges become splines, making it ideal for technical shapes and clean topology-driven designs.
04. Fillet
The Fillet tool creates interactive rounded corners on spline edges. This is perfect for softening hard angles and achieving smoother, more organic spline shapes.
All fillet values remain fully adjustable and non-destructive.
05. Chamfer
Chamfer creates sharp, hard-edged corners on spline geometry. This allows you to maintain crisp angles where needed while keeping everything procedural and editable.
It pairs well with Fillet when building complex spline profiles.
06. Outline
The Outline generator creates an offset outline based on the normals of its child spline. This ensures a consistent distance from the original spline, making it ideal for borders, strokes, and layered line work.
This is especially useful for graphic-style designs and technical line renders.
07. Resample
The Resample tool allows you to add or remove spline points parametrically. This gives you full control over spline resolution without manually editing points.
It is ideal for preparing splines for deformation, animation, or downstream generators.
08. Post Process
Post Process applies Cinema 4D’s internal spline processing algorithms to any object in a fully procedural way. This allows you to leverage powerful native spline operations while keeping everything adjustable and non-destructive.
09. Trim
Trim limits a spline from its start and end points while providing an offset parameter that allows the spline to be animated along its length. This makes it perfect for draw-on effects, growth animations, and controlled reveals.
Combine Them Together!
Respline tools are designed to work best when combined. By stacking multiple generators, you can create custom spline systems that go far beyond what a single tool can achieve.
This approach allows you to build your own super spline generators while maintaining full procedural control.
