Someone recently asked about how to generate a progressive wet melt effect applied to a movie file. So that as the processed movie plays, the wet melt effect applied to the movie gets progressively more extreme over time. This is actually pretty easy to achieve in Studio Artist, by key-framing your wet melt effect over time in the Paint Action Sequence Timeline.
For this post, I decided to use the Default : Water category paint preset called WaterDripDown1. This preset simulates the effect of dropping water onto a vertical canvas, so the water drops drip downwards as they diffusely wet smear the canvas.
