Dot Matrix Painter Filter
That's my first filter for Painter. It's a Dot Matrix with Robot Eyes Shapes embed.
You can use the Smart Material that's ready to use setup. You can choose from some different eyes shapes and parameters. Tweak the look of the pixels the edge of the Matrix, number of pixels, scan line effect, variation, and more.
As a filter you should use on a Layer mask. Don't forget to add EMISSIVE to your shader maps, so you can use that emissive effect and make it even more cool.
You can use the layer under it to "feed" the matrix with anything. Even with a PAINT layer. Anything you paint will be converted to the Matrix effect. Don't forget to change to CUSTOM INPUT in the filter parameters so it can use the layers under it.
Enjoy and free free to reach me out for any question or suggestion.
