Join Larry Mitchell for an in-depth discussion in this video Adding and editing standard terrains, part of Vue 6 xStream Essential Training.
- [Instructor] One of the great thing that you can do in Vue 6 is you can create land, and it's called terrain in Vue 6. There are two different types. Here we have our terrain icon, and we have our standard terrain, and our procedural terrain. Let's start working with the standard terrain first. So, we'll just add that. And here we have terrain added automatically. We can zoom in for a closer look. And we'll orbit our camera down. Hey, let's just go ahead and move the whole camera.
And we can do a quick render of this. And so, we got a basic sense of what our terrain looks like. Let's look at what it's like to edit our terrain. So, we'll double click the terrain icon in the objects page. And here's our terrain editor. We can right click to orbit around this. And just like in the plant editor, you can set it in motion, but we don't really great benefit in doing that in here, at the moment.
And we have some preset functions. For example, we can choose the zero edges, and that ensures that the elevations taper off so that there's zero at the edge of the terrain. This is great if you want to add a mountain into an existing flat ground, so that you don't have the edge of the mountain showing up as an error. This will make it go down to zero. That's pretty useful. You also a peak option.
Which basically makes sure, no matter what land you have, it ends up being a peak. And there's some really neat other options here you can play with. They generate very quick versions of common types of land. And it's important to know that though this dunes, and you see the shape of sand dunes, but you see different color, the color is not representative of how it will be rendered. It's really color banding to help you understand the elevation difference.
So, when you see this orange eerie, you'll know it's not all the way down at the ground level. We'll come back to the picture in a while. Now, let's look at how we make some editing decisions on our terrain. We go to our Paint tab and we can just start painting right away and we can notice that we can actually have very dramatic impact on our land.
Let's undo that, and let's go ahead and rotate it so we can see the whole thing. We can also dig into it. And make an altitude. Basically, set a level here for altitude and you can paint. So, let's lower that to 30. And so now we're painting a different level. And again, that's where the colors come in that we saw earlier. Here we can see this is a lower altitude, because the color is different than this color.
And we're working with the airbrush style, and the important thing about that is if we work with it turned off, we have a very rough response. It's like we have only one value. We have on or off. And with the airbrush turned on, it gives more of a building response. So, it's the default. You have the size of the brush.
And so you can make these very tiny detailed strokes or you can increase the size and make much broader strokes. And the softness, also, can give you a bit of a tapered response. And if you take our flow all the way down and take this softness and size down a bit.
I'll need to, I guess, increase some flow. So, we can see the flow, it's lower, so it's like the strength is lower, in a sense. You can also use a brush image for your actual painting. Let's use this neon. And we'll make sure we're looking at it from the top. And we'll set this to reset, so we have zero elevation. And we'll increase our brush size.
And decrease our softness. And we can paint with that. And the result would be that we have land in the shape of this word "neon." We can see here we the elevation. If we hit okay, now we can zoom into that. And we've created land, which can even have trees and rocks in the shape of the word "neon." It's pretty cool stuff.
Let's go ahead and render that. And here, we can also increase the resolution of that terrain, and let's render again. And so, what that does is that it goes in and it is able to add a bit of definition. Now, of course, part of that definition is based on the brush that we created the terrain with, so when you actually go to choose your brush style, it'll be very helpful to choose something which has a lot of resolution.
Otherwise, you will not get the great benefit of increasing your resolution here. We can also, set this back to mountain, we can also get some erode effects. You can use the cumulatively, so that every time you click on one of these, it actually adds to the previous time you clicked on it. And so you can just totally wash this away. That's pretty neat. I'm going to set this back to regular brush.
And out back to smaller size. Let's undo these. I can just actually set it back to mountain. Don't do them. Here we have thermo, so we have, this is thermo erosion. We can click as many times as we need. Glacial erosion. You can actually see the glacier melting. Wind. Dissolve.
Alluvium. And effluvial. And these last few, they have a hardness parameter that really impacts them. And so, if you set it to soft, you basically have these softer, broader strokes. Whereas if it's set to hard, they're very thin and more precise.
Sort of like a blur filter. Now also, working with the terrain editor, these presets over here of mountain, peak, eroded, all these things here. You can select each one forever to get random possibilities, and so you don't always get the same mountain when you click mountain. Or the same peak when you click peak. In the effects area, you can add grit, gravel, pebbles, all these little options.
Let me reset that again. And add a mountain. You can add stones. These are not the same as adding rocks to your scene, because what these are are basically deformations in your terrain that are in the shape of stones. Let's zoom out and take a look at that. So we can see that these stones effect, really you can see they're in the shape of stones, but it's not the same thing.
So, you want to go ahead and really add your stones usually, by creating rocks from the menu right here. Now, the last thing we'll look at in the standard terrain is the picture option. The picture option uses a loaded picture to define the terrain. So, we can go to our picture and browse and load an image. Well, let's look at how the image is even created in the first place. We'll simply go over to Photoshop.
And here we have this image which I've drawn, and it's just some very soft strokes with a very simple brush. Nothing fancy at all. I just have these basic settings. And I've drawn in different layers and the reason I've done different layers is just to give me more creative control. I have this one layer that has one big, soft stroke. Then I have another layer where I've made the stroke a little smaller and overlapping, but I've adjusted my opacity down.
And by doing that, I've created a lighter color. Well, the lighter color is going to control elevation. And I've done it again and again. This time, I've made it darker to give a difference in the direction of the elevation. And I've saved them all out as jpeg image. And so, now, when I go back to view, I can go ahead and bring that image in here. So, I click on the picture, and then I'm going to go load the picture.
And then, I have the option to control the blending. And the blending is do I use the original terrain information, or the picture, or do I use both, and how much of each one. I'm going to set it to 100 percent of my picture. I'm also going to invert my picture. I'll say OK. And here I have new terrain based on the image from Photoshop. So, I can also apply the paint effects and I can continue to paint on this, if I wanted to.
I'll just say OK, and here I can zoom out. And I can see the land, which was created from the Photoshop image. Next, we'll take a look at the procedural terrain.
