In this course, author Dan Ablan walks through the process of understanding the MODO workflow while learning to create 3D models and animations. The course teaches fundamental tasks, such as modeling polygons and applying materials with the Shader Tree, while exploring scene building in depth through advanced lighting, camera, and animation techniques. The course also covers MODO's schematic tools and shows how to render animations for various playback media.
Creating surfaces in modo is pretty easy to do in the Shader Tree, but sometimes you need a surface that is very specific, such as painting a nice little texture on the gums underneath somebody's teeth. Or perhaps you need to paint right on a model, just to give it that unique look. Well, that's very easy to do with modo's painting tools. So let me show you two ways to do this. First thing I am going to do is very simply just add a sphere here to the scene. Hold the Shift key and click on 1. Press the A key to fit. And what we are going to do is jump over to the Paint tab. And here, right in the middle, you can see the Paint tools.
In order for painting to happen, you need to have an image that is wrapped around your model. So I am going to open up the Render and come down just to the Base Material, and you'll see that, okay, we've got our color wheel we can set. But as soon as I select an airbrush, the tip is automatically selected for me. I can say I want my foreground color just to be blue, let's say, and as soon as I click on here, watch what happens over in the Shader Tree. An image is automatically created for me. Now I can create a new image and be very specific about it, but modo automatically does it for me.
And then with the right mouse, I can choose the size of my brush and then just paint right on my model. So I can set the base color, if I want, for this, to be whatever color I need. And of course the painted color is whatever I choose right here. So think in terms of those teeth that I was talking about, where you've got a base color of just a nice pinkish red, and then you need sort of a highlight color underneath the teeth. You can work your way all the way around, something that might be really hard to do in Photoshopping and line up.
Now the painting can go much, much further than this. Let's take this brush right here. And if I right-mouse again, we get this kind of noise brush. I am going to press the D key, and that's subdivides this model. I am going to just paint with this brush. Now you notice that we've got that noise in there, right? Well, if I change this value from Diffuse Color, if I right-click on it, down to Surface Shading, and I choose it to Bump, now I am actually painting with bump maps. So imagine putting lines and wrinkles in somebody's face.
I can very easily just come over there and just paint those bumps on, just like that. It works very, very well. But let's say you wanted that along with the color. That's where you need a new image map. So in this case, we are just using a default, but let's set up another model, and then we will do this again, making a little more sense. Let's close all. We don't need to save this. Let's jump over to the Layout tab, go to Animals, and let's sort up the Chameleon, then back to the Paint tab, and I'll press the A key to fit in the view, and zoom in.
And with this guy, when you go to the render, you can see that he's got a number of material groups already set up. So let's just go right to the body and select that material. We can select the Airbrush, and you can see here that I've got all of our tools. Our Blending mode is set to Normal and the Normal Projection, meaning that as we look at this, the projected view, we are able to just simply paint straight on it. So that works fine. The Opacity and Density of the brush is fine. Attenuation is the falloff of the brush. So the color of this, we are just going to give him a simple kind of plain green color, something kind of dull, like that.
Move our mouse off there. And then the Background Color is black with 100% Alpha, so that should work fine. Down at the bottom, you've got Procedural Brush. We have it set to Noise, Scale, UV, Amplitude, and so on. We actually want more of this Airbrush instead of the Noise brush. And I am just going to right mouse here, click once, and that image is automatically added for me. And we can just very simply go ahead and paint our chameleon. And because the material group is set up, I don't have to worry about painting over the stems or anything else, because the polygons have already been identified.
So I am not actually going to be painting on those. Now think about in terms of using bump maps for textures and detail. You can really get quite intense with some of these. I've known people that really carve their models using some of the painting tools and sculpting tools. What's neat about this is that you can very easily make it look faded. So let's say we are covering him mostly with color, but now we can take our brush and maybe make a little bit lighter, like this. Right-mouse to size the brush down, and then we can paint along the spine, just to give a kind of unique look, just like that colors were, maybe in these crevices like this.
I am sure some of you are much better artists than me that can really go to town on this. I am also using a simple mouse, a simple computer mouse. This is where a tablet would come in real handy. And then let's make this kind of red down here; give him an evil look. If you don't like that, how could you do? Come to the Eraser, and then we'll just erase that away, because what you are doing is you are actually painting on an image. So this Diffuse Color is an image that's wrapped around here. You can clone it.
You can put a line. You can do a fill, just like this. Fill that up. Smudge it. You can blur it. So, really some of the neat things with those painting tools. You can then, of course, go down to the eyes if you wanted and do the exact same thing. Select that material, perhaps do an airbrush. We can do like some pink eyes in there. Click once. That Diffusion Color is automatically added for us, and then with the right mouse, I can just change his size a little bit and just kind of come in and paint on that eye to put a little color in there.
So it's very easy just to add polygon materials, put different painting surfaces on. Of course, this is just the tip of the iceberg. You can very well paint on bumps and be very specific, and really take your time and put some interesting nodules and skin and all these kind of things on here and really shape the color and tone. So test out the painting. In our next video, we are actually going to put multiple layers on. So I'll show you how we can put a bump map and then how we can paint on top of that.
