ID Map Express

Easily create ID Maps for your models in Blender directly from Edit mode. Select some faces and then assign them a new, unused color in one click.

This is a simple addon that removes the friction involved in manually assigning ID colors to faces. Having to use the paint brush in Vertex Paint mode is imprecise, and the Vertex Paint face selection lacks quality of life features from Edit mode. And picking a color manually can be error prone and tedious.

ID Map Express automates this process, along with automatically selecting a color that isn't close to any other color in your active collection. 

Overview

✅ Works across multiple objects
