I was recently asked about how i put together a dual paint preset that creates a spinning effect used in a paint animation. I wanted to post a simple Dual Paint preset here to show off how to approach this kind of thing. I typically use something like the geodesic Displacement ip op to create the spinning effect. I'm setting the Displacement Option (Disp Opt) parameter to Polar Mod Smooth. If you use a Dir Angle setting of 90 or 270 degrees you will get a spinning effect. Alternatively, 0 or 180 settings will pull in or out accordingly.
You can use almost any paint preset with this ip op and associated settings to generate spinning or travel in/out animation effects. I used a simple time particle paint preset in the dual mode paint preset i provide below as an example of how to generate this kind of effect. Since it's a time particle dualmode paint preset, you should run the preset using loop action in Studio Artist 4 to see how it works.
