Building an FX map, part 1

- [Instructor] As we saw in our previous exercise,…we can create functions for most of the parameters…that we find on a node, which whilst brilliant,…can get a little tiresome if we want to control…quite a few parameters via functions,…as we will need to keep swapping between…all of the function graphs that will be created.…Which is where variables can come into their own,…as these allow us to create all of our function logic…inside just a single graph, and then assign this…as the controller for different options on our node.…

Meaning, we can add a single node…to the parameter that we want to control,…and then have them reference a variable of our choosing.…If that makes little sense, don't worry,…as we will be seeing it in action.…Continuing from where we left off, then,…we can see that our graph has several tabs…running across the top, and so,…let's click on our effects map…and then increase our iterate nodes iterations value…by clicking on it and setting it to around about 400,…which should give us 400 blades of grass…
