 Okay, so let's do a quick review of all the topics that we covered in that section. So we learned how to create a terrain generator, really basic terrain generator, and we're going to go and add more to this as we progress throughout the course. Then we went and we created the erosion HDA, which basically is just responsible for handling erosion stuff, all right? So hopefully it's starting to help reinforce the PDG mentality and understand like how we create steps of our pipeline using HDAs and HDA processors. All right, and then we created the texturing HDA, which handles all things texturing for Unity 2019 terrains, all right, and then we went and we tested that out inside of Unity just to make sure everything was working and to learn a little bit about how the asset links work for PDG and the Houdini engine inside of Unity 2019, all right? So let's keep moving forward. This is the conclusion to the free portion of this particular course, and I really want to thank all the supporters on Patreon and all the supporters on YouTube. I really appreciate it. It really isn't possible without all of your guys' support, so thank you so much. And let's move on to the next section.
