need to distribute multiple shaders on a single object without using groups as I want a smooth transition from one material to another. In this master class (https://www.youtube.com/watch?v=_JQ673B6Y70) at around 32.49 they have achieved something like that using material ID attribute but I have no idea how I can get the desired result. Being a beginner I highly appreciate if someone could help me out and generate a reference file for my better understanding.
