Sculptris is a free sculpting program made for artists. In this course, author Ryan Kittleson introduces the technology behind Sculptris, covers the sculpting toolset, and finishes with two hands-on sculpting projects, where he blocks and sculpts a concept vehicle and a character with facial detail, hair, and clothing.
A very common sculpting task is to rotate a model or just parts of a model. For example, we've got these flippers on the seal and we might decide that we want to angle them a little bit differently. You can use the Rotate tool in Sculptris to get that done. Let's see how it works. So you can click R on the keyboard or just click on this button here. There are a couple of different settings we can turn on for this brush. So let's start out with the Global Mode turned on, and I am just going to click and drag. So what you can see is that the model is just rotating the entire model around.
That's because we have Global turned on, so it's going to rotate the entire model, but also, we have Symmetry turned on. So the model is really only allowed to rotate around the axis of symmetry. I use this mode sometimes when I've sculpted a head and sometimes it's leaning backwards or leaning forwards and I want to just upright it a little bit, so I'll use this mode. Now, let's turn off Global. In this case, rotation only happens within the size of the brush, so it's like a twisting effect. I'm just going to click and drag and once we move the cursor out beyond this circle, you can start to rotate around; it kind of twists things and distorts them. It's kind of a cool effect, but it only affects the area within the size of the brush.
So I'm going to undo that and increase the size of the brush and now, maybe we might get a different effect here, much more pronounced. There's actually one really good way to use this. Let's say, I want to adjust the slant of the eyes. Let's resize the brush, just about the same size as the eyes, and then just click and drag and so now you can make him like sad, puppy dog eyes or a little but more aggressive eyes. That's a really great way to use that brush. Now, let's turn Global back on, but turn Symmetry off, then go ahead and click OK.
I want to zoom out so we can see everything more clearly. With Global on, it's going to rotate the entire model, but it's going to rotate at relative to the view port. With Symmetry off, now the model can rotate in any direction, so it could go skewed off in one direction with the rotate around, then it's going to rotate in a different direction. Now, be careful with this because if you go back into Symmetry mode after rotating, it's going to look kind weird. So let's see what happens with that. So that line of symmetry, since we rotated the seal around, kind of created a little effect.
Now, that might be what you're going for or it might not, so just be careful with that. So I'm just going to undo all of these so we can go back to where we were before. Let's actually use this for some practical purposes for our porpoise. Let's rotate the head up like he's balancing a ball. First, I want to mask off the whole body except for the head. So I'm going to hit Ctrl+D to mask everything and I'm going to go into one of the Draw tools, just so we get our brush back, and let's make the brush bigger. And we're going to hit Ctrl and Alt to unmask, and just kind of brush out the head area.
Alright, we got a nice fall off as well, kind of a gradient from masked to unmasked. Alright, let's go back into the Rotate tool and let's actually make sure we've got Global turned on and let's look at the seal from the side. I'm going to hit Shift to lock that to a side view. I'm just going to click and drag and rotate this a little bit. I might have to do it a couple of different times to get it exactly rotating from the angle that I want. I might want to adjust the mask as well.
I'm going to back into Draw mode so we can have our brush size here. Let's change the size of the brush; I just want to mask off a little bit more, right back to side view. Go back to Rotate, and we'll rotate the head back a little bit more. So it might take a little bit of back and forth, but eventually you should be able to rotate the head back. Let's clear the mask with Ctrl+A and a lot of times, after I rotate things, then I need to do a little bit of cleanup sculpting. So, I'm going to get the Grab tool, and let's see: let's increase the size of the brush and it looks like the chest area flattened out a little bit, so I just want to restore a little bit of roundness to that.
It looks like I might want to resculpt some of these areas as well. I'm just going to go into Inflate, set the Brush size and just clean up some of this so that it doesn't look too distorted. Okay, cool! If we just put a sphere on there, it looks like the seal could be balancing a beach ball on his nose. Rotation is a really great tool to use, especially when you want to pose a character or make facial expressions. I use it all the time.
