GradMagic is an interactive 4 point gradient tool, which can link to cornerpin nodes, and can toggle between live sampling from the plate or baking the color values of the corners.
Can be used for various tasks in prep and DMP,or if you just need a quick 4 point gradient map.
Quick Overview of the properties:
It’s pretty straight forward, heres some basic written steps:
1.) Set your cornerpoints manually or by pressing one of the ‘snap to’ buttons. Or alternatively you can link or bake your cornerpoints to an existing cornerpin node (or any node with 4 “to” knobs).
2.) If you need to adjust the points once they are baked/linked/ in place, then show the adjust knobs, set the reference frame to snap the adjust points near the main points, and you can then move each cornerpoint while it still retains its animation path.
3.) You can either keep the node live, bake the corner colors on a single frame, or bake the colors over a framerange. once baked you can adjust the cornerpoints further if you need to cover up more area. You can adjust the ‘sample size’ at the top if you want to average more colors under each corner point.
4.) Finally you can apply a blur to the edges to help with transition, and you can select the output at the top, whether to show the gradient over the BG input, or just the gradient itself.
