Video: Sketch demo one: Interior shading and texturing

From my iPad's home screen I'm going to click on Sketchbook Pro icon. I need to make sure that my tablet is horizontal, and remember there's a I'm going to go to the gallery. And I'm presented with a base drawing.

Sketch demo one: Interior shading and texturing

From my iPad's home screen I'm going to click on Sketchbook Pro icon. I need to make sure that my tablet is horizontal, and remember there's a switch at the very top here you can click to lock the screen orientation. And there's a cheat sheet in the exercise folder giving you detailed instructions on how to do that. I'm going to go to the gallery. I'm going to open up that first exercise file. And I'm presented with a base drawing. All my line work is cleaned up.

All the shapes are ready to be flood filled. They're contiguous, they have no breaks in them. So now I'm going to go to Layer Control. going to tap on the icon, the upper right. This is the layer, my active layer, and that is the one with all the line work on it ready to be flood filled. And I'm going to duplicate it with the second icon from the bottom Menu bar. This makes an exact duplicate of the layer you had selected. I'm going to hide this, and you'll notice there's a blue outline for your active layer.

Always be sure you check which active layer you have. Now, we're going to find that Flood Fill icon by clicking on the Brush menu. And the third icon over at the very top is your Flood Fill icon. I'm going to choose a color by dragging these circles around, finding something that's a nice soft color. And you're ready to flood fill. Let's click out. And click in surface that you want to flood fill. These two panels are on the same wall, so we're going to make that the same color.

Now, I'm going to add another layer on top of this, and add some textures. So, going back to Layer Control. I see this is my top layer is active. I'm going to add a blank layer on top of that, and this is going to be my texture layer. Click out, and I'm going to choose a texture brush. So I'm going to click on the Clutch, that's this little circle down at the very bottom. And I want to choose, you can choose any of the brushes that you want, but I prefer to use something subtle like the Dotted brush here.

It's now highlighted so that's my active brush. I want to change the diameter to the maximum above 60 and maybe an opacity of 27 or 23. Now, to change that color so that we can see the texture, I'm going to click on my Mixing Pot. And I'm going to reduce brightness. See the difference in the upper right hand swatch. Click Out. Click Out again, and now I'm ready to add some strokes to this. It's a little subtle, so I want to increase the opacity of this texture so it's more obvious.

I click on the Clutch. Clicking on the Brush Properties Puck I can scroll upwards, or stroke upwards. Increase it to about 36. And now it becomes more obvious. And I'll add a little bit here. Now, remember, the further your object is the darker it is. The closer it is the lighter it should be. We're going to adjust it again, increase the opacity to about 47. Add a little bit more. Now I'm not too worried about spilling over the edges.

Okay, now let's see what the difference is, let's go to my Layer Control again, click on this icon. And I can turn on and off this textured layer, so that I can see the effect and hopefully that's pretty clear of what a difference that texture can make. Now, we need to erase all of our spillage. It's when we click on the Clutch. We're going to find our Eraser. And there's two erasers here. You're going to choose the Hard Eraser at the very bottom. You're going to to choose an appropriate size. Let's say 29 with an opacity of 1.0.

Using two finger gesture, we're going to zoom in. And we're going to clean up the excess paint. Now I like to rotate my tablet so that it's at the correct angle for my arm to easily lay some very straight strokes. And you can see how quickly I can erase all that extra spillage. Zoom out, so we can see the full screen, this icon in the very upper right hand corner, tap on that once, and it brings our image full screen.

Let's zoom in again, and clean up this side. Now if I want to become even more accurate, I can reduce the size, opacity is still 1.0, but reduce the size of my eraser to about 11. And that will allow me to get an even closer and with rapid strokes, I can do some very accurate clean up work. Let's zoom out a little bit. There we go. And finally we'll clean this up. Now notice I'm rotating the tablet so that my arm movement matches those edges.

Once again, click on the Clutch, zoom out. And there we have it. I'm going to look at this again, make sure it's what I want, hide and unhide by clicking on this icon, that texture layer. Okay, I like that, that looks pretty good to me. Now, there's an icon underneath, and that's called the Transparency Lock icon. What that will allow you to do is to paint on those surfaces that you've flood filled without it spilling over onto the outside of that shape.

Makes it quite easy. You don't have to do any major eraser. It doesn't always work for every situation, but it is there and it is available. So I'm going to show that to you now. We're going to use that on the right side wall. So I'm going to hide these two layers. Bring back our base and we're going to use the technique called transparency lock. And that will allow you to paint your textures over your surfaces that you flood filled without it spilling over and having to erase. So what we're going to do is when take that base layer, we are going to duplicate it using the two plus symbols here, that makes an exact duplicate of that layer.

We're going to hide the base. So now you have only one active layer, and that's this one right here. We're going to flood fill it now. So let's come out, click out anywhere on your screen, and that will bring you back to your drawing mode. We're going to click on the Brush icon here. We're going to choose Flood Fill again. Change our color slightly. So it'll be salmon color. And we're going to flood fill this wall. Again, it's a very clean shape with no breaks in my line work. So it all flood fills just this area and not spill over on the outside.

If it does, you can always hit Undo. Cleaned up your line work, and flood fill it again. Let's go back to our Layer Control menu up here. Now that we've flood filled this right side of this wall, we're going to click on the Transparency Lock. Come back out. And now, we're going to choose a nice texture brush again. I would say, let's go ahead and choose the same brush we had before. Make sure our size is 60, and our opacity is maybe 37. I'm going to click on the Mixer, and we're going to adjust the brightness.

Make it a little bit darker. We're going to see how this will look on here. Click out anywhere and remember, as I stroke it won't spill over. It'll only stay within that flood-filled surface. So I can be pretty free in how I sketch. Okay. I might want to it a little bit darker, so I can either adjust the color from here. Maybe reduce the saturation. Come in again. Add another set of strokes, a little bit of shadow down here, there we go.

Now I kind of like that. So, let's go to our layers, and let's see what we did here. This is our layer that we just duplicated. We've created a, we added the transparency lock to it and we've added some texture to it. Now you can't see it here but if I turn it on and off, it will actually show the texture being applied. Now the only problem with using the transparency lock is that you won't be able to adjust the amount of texture you've applied, because you've applied it to the flood filled solid walls.

Whereas the first technique I showed you, this one here, you can literally adjust the amount of opacity of your textures as well as any of the various blend modes that you can use. So while the transparency lock gives you the ability to avoid having to erase any spillage, it does lock you into whatever look you finish with, that's what you're going to have to live with. I hope that gives you an idea of how to use layers in your own projects, when you add textures and character to your illustrations.
