Curve to Shape Quick TipS

Creating shapes from blending many transformed shapes or using an SVG node are viable options. Another is this method in which you can create a 1:1 relationship between a Curve and a final custom Shape. You can take this further and do things such as Mirroring for a basic Leaf shape, or Edge Detect for a custom line or piping. All while maintaining the benefits of working with a Curve and not adding additional resources to your file.
