Create pscale
- [Narrator] We've created variations of the line length with our carving system, and now we've created variations of the color with this point vop system. What I want to do is create one more point vop where we modify the P scale value so our lines aren't all exactly the same width when rendering cause we're gonna use curve rendering and we're not gonna actually create polygonal geometry, like tubes around these, but we can use a P scale value to tell the renderer how thick to make each of these lines when it renders them. All right, so I'm gonna make another point vop. I'm gonna call this create P scale. And again I'm gonna make this green. I'm ready to go inside. Okay, so we're gonna do another import point attribute. And we're gonna bring in PNT which is a float, so bring in a float to off the first input and the variable is PNT. And we're gonna use this to drive a random. So I'm gonna type the output of this into a random. Don't need to do the add constant this time cause we only…
