这篇教程教脚本之家的朋友们用AI脚本添加当前高光和阴影到色板，教程主要介绍一下AI的脚本使用技巧。本文觉得不错，非常实用，所以转发过来和脚本之家的AI爱好者们一起学习这个方法，希望对大家有一定的帮助。
/////////////////////////////////////////////////////////////////
//Add Highlight And Shadow Swatches v.1 -- CS, CS2
//>=--------------------------------------
// A simple script for Animators. Takes current fill color from color pallate.
// a prompt will ask you to name the color, then it adds it to the swatch palate,
// along with the highlight and shadow for that color.
//
// feel free to tweak the values to get whatever percentages work best for you.
