Understanding Stroke Modes

You can use any of three different stroke modes while painting: Frame, Interpolate, or Persist. You will use these different modes throughout the course of this lesson.

• Frame When you paint in this mode, you are painting only on the current frame.

  

• Interp When in this mode, you can interpolate your brushstrokes. Go to frame 1 and paint a stroke. Now go to, say, frame 20 and paint. When you drag back between frames 1 and 20 on the Time Bar, the stroke interpolates. If you go beyond frame 20 or before frame 1, the image is black. To insert a second interpolation stroke, toggle through the modes until you reach Interp again, and use the strokeIndex slider to select the stroke you want to modify.

  

• Persist In this mode, the stroke persists from frame to frame. You can change it by going into Edit mode and animating it, but otherwise it will not change.
