Understanding Curve Control
Curves in NeonFX are controlled manually using Bézier handles.
NeonFX does not automatically smooth or reshape a node. A section remains straight until one of its visible handles is moved.
How Curve Control Works
Each node can expose two handles:
- IN
- OUT
These handles control the shape of the Tube on each side of the node.
Moving a Handle
Moving a handle changes the curve without moving the node itself.
This lets you adjust the shape of the path while keeping the node anchored in the same position.
Manual Editing
Curve editing is intentionally manual.
This gives you direct control over:
- Curve direction
- Curve width
- Entry angle
- Exit angle
- Asymmetric shapes
Combine Different Shapes
The same Tube can contain:
- Straight sections
- Smooth curves
- Sharp transitions
- Different curve shapes on each side of a node
The following articles explain how the IN and OUT handles affect the path individually.
