Or erasing parts of lineart without disrupting fills.Īnother application that utilizes this blue pencil and black pencil technique is PAP: The color erase brush blend mode will be useful for erasing color spills without disrupting the lineart. Filling areas that it missed, without disrupting the ink lines. The draw behind brush blend mode will be very useful for fixing errors left by bad bucket fill results. We must draw the entire handle, then clean up the part that is behind the fingers. In this case we have the fingers of the hand covering the handle. When you draw for animation, and in general - it is good practice to draw an object complete, when the object is behind another object and then erase the part of the line that is behind the other object.You can also apply this to selective eraser mode, where the eraser tool can be set to work only on lines that have the same color as the one that is currently set to the eraser tool. We finish the blue line sketch, then we do the opposite, we set a black pencil and set it to overwrite already existing pixels with its color and ink with it:įinally, we execute the "erase all color on a layer" command, with color set to blue! What we are left with is the clean line art: The blue pencil is set to NOT affect existing pixels by drawing on top of them. Then we use the blue pencil to sketch a drawing of the new hand variation: We will start with the previous drawing, but erase the parts that need to be changed: To illustrate this, lets say we have a hand and need to draw a new variation of it.
So if using a blue brush for a rough pass, then draw with a black brush on top to ink it and then erase the blue brush lines bellow. Tvpaint and PAP use this feature in order to allow the user to draw with multiple colored brushes. This would be very useful for cleaning up sketch drawings. Gimp has those implemented and they are great!!
