Why we like it

Auto Vertex Painting earns its place in the Superhive library for a narrow, practical job: turning material assignments into consistent vertex color IDs without manual painting. The version 3.0 update focused specifically on keeping IDs compatible with Substance Painter projects.

What is Auto Vertex Painting?

Auto Vertex Painting handles vertex color ID assignment in Blender by reading the material assigned to each face and giving it a unique color ID. It runs across all separated meshes and keeps those IDs consistent, so a model can be prepared for texturing in one click.

The add-on also cleans up materials automatically and outputs a result ready for Substance. As of version 3.0, it tries to maintain the same color ID to preserve compatibility with a Substance Painter project, a change added following user feedback. Earlier releases launched the tool and fixed a reported bug.

Auto Vertex Painting works with Blender 3.3 through 4.5 and is distributed under the GPL license. A demo video is available, and full documentation is included for reference. It appears in the Superhive library from developer RicardoDev.

Who is Auto Vertex Painting best for?

Auto Vertex Painting is best for blender users preparing models for texturing who need per-material vertex color IDs, including workflows headed to Substance Painter.

How much does Auto Vertex Painting cost?

Auto Vertex Painting is completely free to download and use.

Frequently asked questions

Which Blender versions does Auto Vertex Painting support?

Auto Vertex Painting is listed as compatible with Blender versions 3.3 through 4.5, covering a wide span of recent releases. If you are running a build inside that range, the add-on should install and function as described. For versions outside that window, or to confirm behaviour on the newest builds, check the developer's page before committing. The listing also notes the tool is distributed under the GPL license and includes documentation you can reference during setup.

Does Auto Vertex Painting work with Substance Painter?

Auto Vertex Painting is built to hand off to Substance, and as of version 3.0 it tries to maintain the same color ID to preserve compatibility with a Substance Painter project. It assigns a unique vertex color ID to each face based on the material applied, which is the kind of ID data texturing tools rely on. The developer describes the result as ready for Substance. For details on exactly how the IDs map into a specific Substance Painter setup, consult the documentation included with the add-on.

Is Auto Vertex Painting free to use?

Auto Vertex Painting is listed as free here in the catalog, and it is distributed under the GPL license according to its listing. Licensing and pricing terms can change over time, so for the current details it is best to check the developer's page directly. The listing also shows a rating from a small number of reviews and notes the add-on has recorded ten or more sales. Documentation is included, which helps once you have access to the tool.

How does Auto Vertex Painting handle separated meshes?

Auto Vertex Painting works for all separated meshes and keeps the vertex color IDs consistent across them. It sets a unique color ID on each face based on the material assigned to that face, so a multi-part model can be processed together rather than object by object. The stated goal is finishing texturing prep in one click, alongside automatic material cleanup. If your scene mixes many separate objects and materials, this consistency is the behaviour the tool is designed around, as described on the developer's page.
