LightBurn doesn’t support vector clipping masks.
I suspect the easiest way to handle this would be to use the Tools->Cut Shapes feature. It performs a cut on a shape using another closed path shape.
In this case:
- Inset the outline to create cut shape.
- Group all rattan pattern components
- Select rattan pattern, then add cut shape to selection
- Tools->Cut Shapes
- Discard outer portion of cut shape
