IDMapper - a complete walkthrough (old version of tutorial)
IDMapper is available on Blender Market https://blendermarket.com/creators/va...
In this tutorial I show how to use IDMapper to create a vertex color layer that can be used as an ID-map in Substance Painter. It goes from letting IDMapper assign colors to regions of the mesh, tweaking this assignment interactively and copying the vertex color layer to a high poly version of the mesh. It also briefly shows how to use the id-map in Substance Painter to quickly mask substances.
