2. Select the shapes you want to have. (Press ctrl + A in the viewer to select all)

3. Run the script by going to the new menu Roto > renderSplines

4. A new node is created, in which you have control over color, size and filter type

5. You can merge the created Overlay over the background plate or leave it

Example 2: the renderSplines merged over background

How does it work:

1. Create a roto node for every shape in selected node
2. Clone the shape and transformations into single node
3. edgeDetect and erode the single node
4. merge all nodes together + a colored constant
5. copy and premult
