Creating a Custom Brush

Dogwaffle supports several types of brushes. One category is based on particle systems, the Optipustics brushes. Another is a collection of internal brushes using small images from a brush set. Then there's a category of brushes which Dogwaffle calls the Custom brushes. They are made of large images, potentially even larger than the image buffer they paint on. And, they can be made of more than one image. If they have 2 or more images loaded, they're called custom animated brushes, also known simply as animated brushes. You can for instance use them to hold a walk sequence from a cartoon drawing or Poser or other 3D rendering, and freely paint with that, over an image or into another video or anmation.

There are many ways to make or create an animated brush. Some methods create them from scratch. There are also special FX tools that create animated flares and lights. Other methods consist of creating a multi-image or multi-frame brush but they initial frame sequence doesn't appear to change. Still, they are made of more than 2 frames, hence it's animating across the brush frames when used for painting.

In this tutorial we'll create such animated brushes and apply changes to its frames so as to further turn them into visibly animated brushes.

Creating a Custom brush from the Brush Settings panel

Left-click on the upper-left icon in the tools panel. This opens the Brush settings panel, also known as brush options (keyboard shortcut: 'o' for options)

Click on the 'Custom' tab. This shows an area for controlling parameters specifically for custom brushes.

Notice for instance that there's a checkbox: Allow custom brush transforms. This is because custom brushes can potentially be very large and time-consuming to apply resizing and rotation transforms on-the-fly, so my default they're disabled. (random position is not affected because there's not much overhead to position the brush image.)

You can create a circularly shaped custom brush image right in there.

The brush radius can also be set with the slider or value widget.

Set the Bias to 100 if you don't want the edges to fade from black to grey and to white.

A quick dab with this brush may show a soft grading at the end of the brush stroke.

This is likely due to the default Opacity not being at the max value.

Now we have a cleanand sudden ending:

So far that's just a single-frame brush
