The shape of the body is included in all the shading layers in this file. And if I wanted to erase a part of the color layer, I had to erase the same part in all “clipped” layers-because they weren’t really clipped, they were just copied. In the past if I wanted to add a Multiply layer above the color layer, that was clipped to the same area, I had to copy the color layer and fill it with white (which in the Multiply mode renders as transparent). Second thing related to it is that you can clip multiple layers to one mask. You can’t Lock Transparency to a transparent layer-you always have to start with some base color. So what’s the difference between this new feature and the Lock Transparency function we’ve been using before for the same purpose? The most important difference is that the Alpha Mask is transparent. Isn’t it the Same as the Lock Transparency Function? You can use this layer to quickly “erase” parts of the layers below just by painting on it. There’s also another new mode, called the Inverse Alpha Mask. If you want to see the mask before doing these changes, just switch it back to the Normal mode (and maybe lower the Opacity to see the layers below), and then back to Alpha Mask mode once you’re done with the edits. You can even change the Opacity of the mask to make the clipped layers more transparent! Remember that erasing a part of the mask doesn’t really erase anything below-it just hides that area! If you want to edit the mask, just paint on it-you can erase it, repaint it, smudge it, move it around, and this will automatically affect the look of the layers below. The “cast shadow” layer is outside of the group, so the mask doesn’t affect it. So you can have separate layers for the colors, shadows, shine, textures-all clipped by default! If you want to draw something that is not clipped, just create a layer outside of the group, or above the Mask layer. You can add as many layers below the mask as you want-as long as they’re inside the group, they will be properly clipped. Now go to the Clipped Layer and start drawing whatever you want-Sketchbook will not let you cross the borders defined by the mask! You can hide the Mask layer to see what you’re really drawing. This will make the shape disappear, as it’s no longer a part of the drawing-it’s simply a definition of the area that you want to limit your drawing to. Time for the most important step: change the Blend Mode of the Mask layer to Alpha Mask. Step 5īy drawing the line art you’ve created an inside and outside of the object-draw that inside area on the Mask layer using a hard brush. You can also download the sketch I’ve used here. Keep it simple, just for the demonstration purposes. Name the upper one Line Art, the middle one Mask, and the lower one Clipped Layer. Step 3Ĭreate three layers inside the group. This will ensure that whatever you do inside the group will not affect the layers outside of it. Step 2Ĭhange the Blend Mode of the group to Normal. Grouping layers will help you quickly separate the clipped layers from the non-clipped ones. Go to the Layers panel and create a New Group. So it may seem pretty unhandy at first, but once you see how it works, you may discover you actually like it more! Step 1 How to Create a Clipping Mask in Sketchbook Proįirst of all, if you’re familiar with the Clipping Mask feature in other programs, I have to warn you that it looks very different in Sketchbook. Yes, that’s right-the newest Sketchbook Pro update gave us the long awaited feature, the Clipping Mask/Alpha Mask! Let me quickly show you how to use it and why it should become an essential part of your workflow from now on.
