Figure 11-9.A closed polyline mask now shows in the flow node tile for your mask node

Now you’re ready to refine your polygonal mask, making it into a polyline mask —or a Bézier mask, more precisely—by selecting the arrow (point select) tool. Or, you can use the add point tool, as long as you only click on your points to select each one for editing. Use the handles to adjust the curvature of the polygon, point by point, until it fits snugly.

As you can see in Figure 11-9, I have turned all of the straight lines into custom curves, and this polyline mask edge-fits the model fairly nicely at this point. You can continue to refine your point placement and tensioning handles if you like.

Next, drag a wire (pipe) from the Polygon1 mask node into the BlurNiki node mask input. As you can see in Figure 11-10 in View2, your mask now defines where your effects will be applied.
