Learn about basic brush settings.
- [Instructor] In this video, we're going to take a look at the brush settings, kind of just go through the overall workflow of using a brush. So here on our Shelf, let me just expand this a bit, we have a Brushes category, and here you'll see a list of brushes. Now, these brushes are just presets, and what that means is that here when you have your properties, when you're using the brush tool here in the toolbar, these presets are just going to set up automatically a lot of these brush settings for you. So for example, right now, I'm just using the default soft brush, which basically has a lot of these parameters set to zero.
So it's just a real basic brush. And if I click one of these presets, like for example this Dirt, you can see here that it the changes the jitter for my size and angle, it changes the alpha, and so on. So again, it's just a preset for the settings, and you can start with the default soft, make your own brush, and then save that as a preset as well. And we'll cover that in a later video. But for now what we're going to do is just kind of go through the settings, so you can understand how the brush system works. So, the brush here at the top of the toolbar, just this brush here.
And if I click and hold this down, we get a brush, and then a Physical Paint, which is talking about the Particle Brush. So here we're just using the regular brush. Now, the brush and the material basically go hand-in-hand. Because whenever you set up a brush, you're always going to have some type of material set up, and in the previous videos, we've been discussing how materials work. So in this case, I'm just going to select this material. And just for the demonstration of the brush system, what I've done is I've just disabled all the channels, and I'm only painting on the color, and I chose kind of this bright blue, here, so that when I just paint, you can clearly see what we're doing here with the stroke.
So here I'll just click this button to just navigate or scroll the Properties panel back to this Brush Parameters section. And you'll notice here that in the Texture Set list, we're painting on the base texture set. Now, you can only paint in one texture set at a time, so for instance, if I start to paint and I move my brush across the different texture sets, the stroke is not going to continue across that. So basically, what we're looking at here, is that the strokes are going to be isolated to the texture set that you're working in.
So, now let's take a look at some of these core parameters here. So let's just minimize this shelf, and let's take a look at what we have. All right, so our size, it's a very important setting here for your brush, and we can change the size of the brush using a keyboard shortcut or this slider. So you can change the slider, you can click on this pencil icon and type in a value, if you want, but it's best to utilize a keyboard shortcut for that. And so, what we're going to use here is just the Control key, and then the right mouse button, and I can move the mouse from left to right to adjust the size.
So it's right mouse button with the control key, moving the mouse from left to right. And that's going to adjust our size. And we can start to see here in this viewport window, kind of dynamically what that size is doing here to our stroke. Now, this viewport window is actually kind of a dynamic window itself, so I can click and start to paint in here, so if I mess with some of these parameters, I can just do a quick test stroke in here to see how these parameters are affecting my stroke setting here. So here we have our size. We also have flow setting here, so here, let's just decrease our size down, and we have Flow.
So right now, at 100%, that means we're basically just having 100% of the paint just coming out of, or flowing out of the tip of the brush here. So that's what we get. If we adjust our flow, so if we bring this down to a pretty low value, you can see that it's almost like an opacity effect. But this flow kind of builds up, so as I start to just paint back and forth, it just gives me a way to kind of build up paint. And a lot of times, especially if you're working on characters, or something organic, this is a really good way to work to interactively adjust this flow. So let me just undo that.
Now, the size and the flow also have the ability to work with pen pressure. So if you're using like a Wacom tablet, so here if you come over to this button that's next to the pencil, you can see that we have the ability to turn on pen pressure. So this is pen pressure on, and this is no pressure. So right now, our size has pen pressure. If we want to have that with flow, we'll just select the button and choose pen pressure. And I'm not, I'm actually using a mouse right now, so we won't see that, but if you're using like a Wacom tablet, like I said that pressure will affect the size and the flow.
So here, let's take our flow, well here, let's look at it like this, and also let me just talk about another keyboard shortcut for this. So here we have our size. Now, for the flow, I can actually hold down the Control key, and the left mouse button, and I can move that from left to right, basically I'm moving the mouse is what I mean. So Control key, left mouse button, and then move the mouse from left to right, interactively adjust that flow. So I'm just going to push this back to 100%. So the next setting we have here is our spacing, and you can see with the spacing setting that I have right now, if I just start to paint a stroke, I get a pretty continuous line here.
So if I adjust my spacing, you can see well, I'm just spreading out the spacing of the stroke, and so now I can get more like a dot like this. So that's what spacing is going to do for you here. Now, speaking of lines, another way that you can draw lines and be a bit more accurate with this here, actually we'll drop that spacing back down, is, let's say I want to draw a nice, sharp line. I can just start my line, I'm just going to hold down the Shift key, so I'll maybe left click, hold down the Shift key, and now you can see that I get this dotted line here, or this dashed line, and if I just pull this down, and then just left-click again, I get a really nice straight stroke here.
So again, just left-click, hold down Shift, and then left-click again and this will give me a straight line here. So that's how you use the line tool. Now, we have this angle setting, which is actually pretty important, but it's going to be really difficult to see with this round alpha that I have. So I'm just going to switch the alpha. To do that, I'm just going to quickly just select the button, here, and I'm just going to use a new alpha, I'll choose this claw. So I'll select this, and now I have a new alpha. I zoom into my viewport, here you can see what that tip of the brush looks like based on this alpha that we chose.
So now, if I want to rotate this here, I can hold down the Control key, the left mouse button, and I can move the mouse up and down to dynamically rotate, or change the angle of the tip of the brush. So here I'll just change the angle, left-click to stamp down, left-click, rotate, stamp down again. So again, that keyboard shortcut is the Control key, left mouse button, move the mouse up and down to change the rotation. All right, so we'll undo these strokes here. Let's set our alpha back, so again, just really quick, I'll hit this preset here, this is the default soft brush, and you can see that it just changed the alpha for me.
So the next group of parameters that we have are the jitter settings. And so these are good to get more of a chaotic-type brush. And like the dirt brushes utilize this a lot as well. So, if we take a look here at our size, I'm going to take the size and just size jitter, bring it up to pretty large here, so we'll put this at like, almost 100%. And then if I start to paint, here in the viewport you can see that, well, the stroke is different. It's just randomly changing the size for me. So sometimes it's a little smaller, sometimes a little larger, and so on.
You can kind of see that here in the preview window as well. Might be a little bit easier to see if I increase that spacing. There we go. That makes it a little bit more apparent. So you can see some of the strokes are smaller than others. So just randomizing the size feature. Flow, same thing, so we just increase that flow jitter. You'll notice that some of the flow is just being randomized again, so some strokes are lighter than others, because the flow is being randomized. So, that's what we're getting there. And then also we have our angle jitter, so to do that, again, let's just go back, choose our claw alpha, and just increase this angle jitter.
And then I'll start to paint, and you can see again, it's just randomly rotating or changing the angle of the tip of that brush as we paint. So we'll undo that, and again, just default soft preset to take us back to that soft alpha. And then finally, we have our position jitter. Now for this, I'll leave my spacing here at 20, since I hit that preset it reset everything for me, so here at position, we're just going to increase this pretty large here, and as I start to paint here, you can see what this is going to do.
Now, what this is doing is just randomly changing the position of the tip of the alpha, where it is underneath the mouse. So as I start to paint, you can see that this is giving me more of like a splatter brush, or a spray brush, or something like that. So again, really good for the dirt brushes and things like that. We'll just undo, and so here's just the base settings that we have. So in the next video, what we're going to do, is we're going to take a look at the alignment, backface culling, and we're going to talk about how those affect your brush.
