- [Narrator] Wrapping up our chapter on Entourage, I'd like to talk about how to paint X-gen attributes such as the density of primitives or length or color or any other attribute. So I've got a scene here with a simple plane and I've applied some graphs to it. I'd like to mask off an area here in which we will get fewer or even no grass primitives. And that's accomplished in the primitives tab from the mask attribute. We have the overall density and then below that is mask and that's a multiplier for the density. Currently, the mask has a value of 1.0 meaning it's multiplying the density by one, it's not changing the density at all. After that numeric value we see a hash symbol indicating a comment, and after that, we see the word map that is actually a global variable in SE expression, and it points to a particular map file on disk. The location of that file is indicated by the string here, and we'll see a dollar sign…
