<![CDATA[[EXAMPLE FILE] live draw with Pattern Brush]]>Is there a way to create a pattern brush using live drawing with imported images? 

Follow up, is there a way to instead of using mouse watcher, use motion tracking/webcam to draw using said pattern? THX

This seemed like an interesting project to tackle... so I made a demo file using a different approach.
I created a feedback loop into a Matte++ actor using a freeze actor. I think this approach is very flexible. Currently it has a random shape from a shapes actor as the 'brush' but you can use any image (alpha around will help :)
I might expand this a bit and make it a new User Actor offering on the Add-Ons page, what do you think?
Hope you like it!

yes, and yes.

The Live Drawing actor essentially needs 3 things in order for it to draw - x position, y position and a trigger. any numerical data can control the x and y, you may need a Limit Scale Value actor to adjust this data before it gets into the Live Draw. Try getting the x and y from an Eyes actor. You can connect any of these also to the Trigger input to get constant drawing whenever something changes in the input video.

Once you have control over the drawing, you can feed the image into an actor that will unveil your image (coming from a Picture Player) - Effects Mixer might work, or one of the Keying or Masking actors. Many people use the Mouse Watcher as a temporary input whilst they are patching, then replace it with whatever input system they are using once the desired output effect is achieved.
