866 Repurposing and inverting masks

- [Instructor] In this movie we're going to repurpose that layer mask that we created in the previous movie in order to create this purple watercolor shading inside our robot. So once again here I am inside Adobe Sketch, running on an iPad Pro. I'm going to tap the home icon in the top left corner of the screen in order to switch back to my most recently opened documents. And I'm going to open this guy, masked robot. All right now, I'll tap on the top layer in the stack over in that column along the right-hand side of the screen. And I'll tap the plus sign above the eye over here to the right of the layers in order to create a new layer like so. All right, now what I want to do is paint inside that layer using my watercolor brush. And so I'll go ahead and tap and hold on the second tool over in the left-hand toolbox, which will bring up my live brushes. And I'm going to tap on the word oil. Tap on watercolor in order to bring up my watercolor brushes and select watercolor wash soft. All right, now I want you to notice down here near the bottom of the toolbox that I've got a size value of 100 pixels. I've set the flow to 40. And I've gone ahead and set the water flow to 90. So, very High. And now, let's say I want to lift a color from my artwork, then I'll just go ahead and tap and hold in any old place inside the artwork like so, which will give me this eyedropper. And so, I'll go ahead and move it over to, let's say this location here in order to get this shade of blue. And then I will begin painting on this layer. Now, I'm not being particularly careful as you can see. I'm just painting away down the arm, for example. And I'm going to paint all over the place. And so I'm creating much more shading than I need. All right now, I'll just go ahead and paint down here along the right side of the robot's body. And so I'm just scribbling away, because ultimately, thanks to that high water flow value, my colors are going to bleed into each other quite nicely. All right, now I'll paint up into the head. And if you like, you can lift other colors and add other colors to the mix in order to get a little bit of variety. But I don't want to bore you to tears here, so I'm just going to go ahead and throw down some watercolor like so. And then I'll paint in some more into the body here, and maybe down into the stomach. And that is looking pretty good. And so I'll just go ahead and finish things off. Now, obviously, I need to do some blending and masking. And so notice that the watercolors are currently lightening the line art, and so we're getting a kind of muddy effect. And so what I'm going to do is change the blend mode by tapping on this little settings icon in the top right corner of the screen, and I'll change the blend mode to multiply. And we'll get an even, darkening effect. So now those black lines are remaining black. All right, now we want to take that mask that I already assigned to the watercolor backdrop, and we want to repurpose it, because after all, I've already masked away the robot. And so what I'll do is I'll tap on that layer, the second to bottom layer, and then I'll slide it over to the left just by dragging like so. And then I'll tap on that ellipses icon, the dot dot dot right there, and I will choose copy mask. All right, I'm done with the masks, so if I like, I can go ahead and slide it back to the right, so that I'm seeing the image thumbnail. And then I'll tap on the top layer in the stack, the one that I just created, and I'll tap on that dot dot dot icon once again, and I'll choose paste mask in order to mask away the contents of the robot. I want exactly the opposite effect. I want to see the shading inside the robot, and so I'll tap on that dot dot dot icon again, and this time choose invert mask. And that will give us this effect right here. All right, now all that's left to do is smooth out this layer mask. And so I'll go ahead and tap on the top tool in order to bring up my pixel brushes. And I will select basic from the list right there. And I'm going to go with this guy, soft round opacity. Should work out nicely. And I'll go ahead and hide those brushes. And then you want to tap hide down here at the bottom of the screen, and go ahead and paint some soft transitions into your layer mask. And you can be as careful as you like. In my case, I'm not going to be super careful, because it would take a little bit too long, and I'm confident that by now you're getting the idea. But it's just a matter of painting away until you get the soft transitions that you're looking for. So I would just go ahead and paint down into the tummy a little bit, and over along this left-hand arm as well. And then if you want to add some more watercolor, all you need to do is slide that layer mask at the top of the stack over to the right-hand side, so that the image is now active. Then switch back to your live brushes, so that you can choose that watercolor wash brush. And then if you like, you can tap and hold inside the image in order to lift a different color. And then just go ahead and paint inside that image like so in order to add more watercolor. Which will require you to adjust the layer mask, so it's going to be a little back and forthing, but that at least gives you a sense for how you might repurpose and invert a layer mask here inside Adobe Fresco.
