![]() And that's nice because it can help you stay consistent. The brush is shrinking relative to the screen if we zoom out but it's staying the same size relative to the model. So, if we sculpt something here, and then zoom out, sculpt again, so on and so forth. So, now the way this works, no matter how close you zoom in, the brush always stays the same size relative to the model. ![]() I'm going to hold down shift and click on dynamic to turn that on. Now, let's see the new feature called dynamic brush size. So I'm going to hit control z a few times to undo that. If I zoom out even more, you can see now it's just completely taken over the model. So, just to demonstrate, I'm going to to sculpt something here and then zoom out somewhat and then sculpt again and you can see that that sculpting is really different in size. Even though it's the same size relative to the screen. Or conversely, if you zoom in really close, now the brush is really small compared to the model. However, where this started to become a problem is that you might be working on a part of your model and the brush size is really good for working on details at this size but if you zoom out a little bit, the size of the brush stays the same relative to the screen but it's bigger relative to the model. And that's easy to understand, it's just the size of the brush on the screen. So, if you set it to something close to 500, then it means that it's about a thousand pixels from one side to the other. So, what ever this number is, is the radius of the brush in pixels. And this way draw size is based on the size of the brush on the screen. So, make sure that dynamic is a darker gray, so that it's off. ![]() So, first let's talk about the traditional brush sizing before dynamic came out. With the more recent versions of ZBrush, ZBrush has included something called dynamic brush scale, which is on by default and it's right up here with the draw size and to turn it on and off, you might think that you just click on dynamic, but you actually have to hold down shift and then click on it and then you can turn dynamic on and off by holding down shift and clicking. In this video, I'll show you all the settings and circumstances that effect brush size, as well as getting it under control. Setting the size of your brush really should be the simplest thing of all but in ZBrush there are a lot of complications that make it frustrating to manage. ![]()
