IDMapper add-on verified for Blender 4.1


I am pleased to announce that IDMapper is now verified for Blender 4.1. 

It has been tested against version 4.1.1 of April 16, 2024, and no changes were needed.

Blender 4.0 introduced quite a few breaking changes, so this version is not backwards compatible with 3.x

Although no new functionality was introduced in this release, please be aware of the following:

  • IDMapper can currently not work with facemaps, because they are no longer supported in 4.0. This may change in the future (hopefully, see this discussion) and if possible I will try to get this back into IDMapper. Meanwhile, I did create a small, free add-on to make selecting faces from facemaps possible in 4.0 which may be useful in some workflows.
  • Color picking in Face Paint Mode (with the S-key) is no longer restricted to the 3d-View area, so colors can be picked from anywhere in the Blender application (although still not outside of it).

IDMapper simplifies creation and editing of vertex color layers that can be used as ID-maps in texturing software like Substance Painter or Quixel. It aims to reduce the time it takes to create an ID-map significantly, especially for complex hard surface models. It uses powerful heuristics to create an ID-map from scratch and lets you interactively adjust the results. It offers options to use existing information, like uv-seams, but can also intelligently assign the same color to similar mesh parts. 

The new version is available on BlenderMarket.
