ZBrush: Tips and Tricks

- [Instructor] The History Recall brush is a brush that allows to reproject history details into your mesh. The purpose of this brush is to be able to go back in time into your history without losing your current history of what you've done. It is a non-destructive way of undoing and experimenting with what you've done. Let me demonstrate. So what I'm going to do first is going into Lightbox. So hit comma or click on Lightbox right here. And let's go ahead and grab the demo head. Let's put him full-screen. So what I'm going to do first is sculpt and make some changes to this guy. So the first thing I'm going to do is add some jaw and stuff like that. So I'm going to go and grab my move brush, like so, and increase my brush size a little bit, and then just move his jaw a little bit, and then maybe make his forehead a little bit bigger like so and then let's use the clay brush. So let's go and use Clay Buildup and add some details here. So I'm going to increase that. So I'm going to add some details like so, add more details around his cheekbones like so, and make him really non-human as possible. But I went ahead and I actually speak to the client, and the client tells me, "Well, these details, I don't like the forehead. "It is way too in the front "and I don't like these details here." So let's say, for example, I'm just polishing this, and I made the forehead slightly bigger just for demonstration purposes. So Brush, Move, V, and then increase the size like so and make this really big. All right, so now I have something that's tweaked. So if you want to undo something, typically, in the history, you would just undo it and just continue from there. But that is not a really efficient way of working. So basically, ZBrush introduced the History Recall brush recently. So let me show you how it works. So I want to basically keep all of my other changes but the forehead I want to basically go back to a point where it was normal. So let's go back to where it was normal, all the way to probably around here. Okay, so that was my normal forehead. I want to keep all of the other changes, but not this area here. So what I would do is use the History Recall brush. So let's go ahead and grab it. So let's hit B for brushes and then H and then use this one here, so R, or click on it. So what I would do first is click in the timeline where I like the forehead. So I'm going to hit control and click on the timeline. So now it's going to turn white, and then what I could do is go all the way to the end, where I have all of the other changes that I like, but I don't like these changes here. So what I would do is, just decrease the brush size first, is just brush the history all the way back to this where I brush. So if I start brushing, and you can use symmetry with that, so we have to remove the symmetry, and I would basically brush the forehead all the way back to this point without losing my other details in the jump. So I would go ahead and basically remove the forehead that is way too forward, like so, and then I could hit shift to just smooth out the transitions in between my changes like so, and then I would keep my jaw, and then the forehead would be all the way to where it was in that point without losing any history. So I could even go back before I made the changes to the forehead and then do another control-click and then make changes again. So this is really useful if you want to go back to a point where the mesh in the specific area was better, and then you want to keep some of the details here but not here. So you would use that brush to actually go back in time for that specific area. So this is really useful when we want to make those changes and experiment.
