substance designer bezier curve node
A node on a Baez curve, which I find very useful, is able to adjust the curvature like a pen tool.

The original node was made by Suzukimy, and I modified it on the basis.

The question that has been puzzling me before,
Quadratic Bezier Curve is available in SD, just like the pen tools in PS.
There is also the pattern of petals or leaves turning over in SD,
I think these two nodes are very useful for patterning.
Create a petal node, adjust the position, copy the node and connect it to the input, adjust the curvature position, you can get the effect of petal folding
