Join Henry Santos for an in-depth discussion in this video Using the Paint tools, part of MODO Essential Training.
- [Instructor] So, now let's take a look at some specific tools for painting, and we have this terrain that we worked on before. I went ahead and added trees to the entire terrain, and we can see that if we click on the F8 key on the keyboard, we can bring up our preview window. Let me close this and I'll show you where you can access it in another location. If we go to the Render pull down, we have Open Preview and F8.
So, we hit the Play button. Just want to make sure that we have trees there. They look pretty good. So, I changed the settings already so they looked the way I want them to look. Looks pretty cool. A lot of trees in there and again, this is with a replicator, so it redraws the trees very efficiently. Now, if we had a variety of trees. If we had different scattering patterns, we could improve that, and for the sake of this lesson, let's just take a look at this and let's see how we can add detail to the terrain that they're in.
Right now, it's just a green field, but let's paint some terrain. I'm going to close this preview window. There it is. So, right now we just see the boxes and that's good enough for now, for what we're doing when we're painting. Let's look at our shader tree. While we have the terrain selected, let's look at our shader tree and scroll down and here's our terrain material. Open that up, and we do have a Terrain Paint material on there.
Great, and that is a png file, so it's a little bit more efficient. Now, let's go to our paint tools. While we have the terrain selected, let's click on the Airbrush. That's what we're going to use to paint onto that surface, but this time instead of selecting just a regular paintbrush let's look at the Image Ink. What Image Ink does, click on that, is it takes an image that we select and it places it grade out or faded on the screen, and wherever we paint, that image is going to be essentially plastered onto where we start painting.
So, we need to be aware of how far or how close it is to add more or add less detail. So, first thing we do is we go to our properties. Let me raise this up a little bit. We still don't see Image Ink option there. I'm gonna click on this double arrow, bring that up, now we have the Image Ink box here. So we could select what image ink we can place on there.
I'm gonna click on that and we have a few default images that we can select from. You can add more. You can design your own. The possibilities are endless. So, let's just use this ink 14. So that is selected, so ink 14, so now that's gonna show up on our screen. So, let me zoom in a little bit closer. So, let's start painting. There it is, and there it is. So, that faded image of the grass is showing up.
So, I just did a corner here and I'm gonna zoom out and that looks a little large. So, there's like giant blades of grass. So, let's go closer and let's see what happens. That's better. So, we need to stay this close to the model. So, we're gonna move around and it's like we're painting with a stencil. So just as stencil has a set size, so does our image ink.
So, we can even zoom in closer and add finer detail. So, I'm going to paint the rest of this terrain and when I get back, it'll be all done and then we can start adding other bits of detail. So, here we have the majority of the environment painted. Let's add a little bit more detail. So, you can see there I kind of mixed it up and added a different brush. So, let's go ahead and add another texture there. So, Airbrush, Image Ink. Let's select a different map.
Let's do this ink 18. So, let's get closer up here. There is our brush size. Once we start painting, there is the image of our map. So, we can shrink that down, but if we do that then it starts doing that tiling thing, so let's undo. Let's scale that so it's larger and our brush is within that map and then we can just dab this new texture on there and let's change our opacity.
So right now it's at 60. Let's say 20. So, we're just gonna add a little bit of variety to our terrain. So, we can keep laying on top of each brush stroke a new terrain. So, in no time at all we used the Airbrush and painted on this terrain and created this really cool environment, and it really didn't take that long.
