Add POP Color
- [Instructor] The final node we're gonna add into our particle simulation is a pop color node. So let me pull this over here. Under our popadvectbyvolumes node, I'm gonna right-click here and do POP color, lay this down; and then we're gonna hit the P key and under the Color tab, we're gonna change the color type to Ramp and we're gonna use these defaults. And this is what we did in the last chapter too, and basically what this is functioning as is baking in our normalized age as a color value from zero to one. We aren't gonna use this as the color of the particles. We'll color our particles later, but this basically gives us a lookup ramp we can use; and so this is really effective. Okay, so that's all set up. We've got our particle source set up. We have our popadvectbyvolumes and we have our pop color, and so what we're gonna do next up is just cash out our particles and then we can move on to turning those into trails.
