Spline Sweeper
A powerful mesh generation tool that creates complex geometries by sweeping profiles along spline paths with just one node.
Quick Links
Overview
The Spline Sweeper component revolutionizes mesh generation in Unreal Engine by allowing you to create complex geometries with a single node call. Simply define a spline path and a sweep profile, and the component handles the rest - generating optimized meshes that can be used in construction scripts or at runtime.
Key Features:
- •One Node Operation: Generate complex meshes with a single function call
- •Runtime Compatible: Works in construction scripts and during gameplay
- •Custom Profiles: Includes preset profiles and supports custom sweep shapes
- •Auto Cleanup: Efficient memory management and mesh optimization
Setup Guide
1. Installation
Download from the Unreal Engine Marketplace and enable the Spline Sweeper plugin in your project settings.
2. Component Setup
Add the Spline Sweeper component to your Actor:
- Create a new Actor Blueprint
- Add a Spline Sweeper Component
- Add a Spline Component for the path
- Configure the sweep settings
3. Spline Configuration
Set up your spline path:
- Define spline points in 3D space
- Adjust tangent handles for smooth curves
- Set spline point types (Linear, Curve, Constant)
- Configure spline density and resolution
4. Profile Selection
Choose or create your sweep profile:
- Select from built-in profiles (Rectangle, Circle, I-Beam, etc.)
- Import custom 2D shapes
- Adjust profile scaling and orientation
- Configure UV mapping settings
5. Generate Mesh
Call the sweep function to generate your mesh:
- Use in Construction Script for design-time generation
- Call at runtime for dynamic mesh creation
- Apply materials and collision settings
- Optimize mesh for performance
