 Okay, so in this section we are going to take a look at creating a Unity terrain from a height map exported from Houdini. Alright, so let's do a quick review before we get started of all the core concepts that we are going to cover. So first and foremost, we need to actually import the Unity terrain tools into Unity. Alright, so I'm going to show you where that is and where all the panels are for it. Okay, and then we're going to learn how to export a height map from Houdini. And then look at how we convert that exported height map to a raw format so we can import it into Unity. Unity requires that we import it as raw format, which I wish they would actually change, but that's just me. And so finally then we're going to take a look at creating the base terrain material. Now this is not necessarily required, but I want to show you guys how to do it so you can create your own custom materials for your trains. Okay, so let's get to it.
