2D Modifier - Motion blur effect with configurable feedback loop
The feedback's principle is to combine the current input image with its own previous output.
A particularity of Smode is that you can tweak this feedback loop by applying any chain of modifiers on it.
Here are three presets of feedback using this principle:
Bacteria
Side Trails V
Glass FX
