ShadeIt is a new script for Maya by Romain Chauliac that will let you easily create and edit real-time shaders for Maya. 

ShadeIt is a companion for your Hard Surface stuff. Shaders are built to give the best look in Viewport. The idea is to shade you model while you’re modeling! It’s not dedicated to final texturing/shading. It’s more like a quick shading blocking, that will help you during your modeling and give you the ability to make nice presentation without rendering, etc.

ShadeIt is working in Maya 2016 to 2019 for Windows and MacOs.
