Earns its place as a focused utility for a specific pipeline gap: moving Decal Machine decals into Substance Painter and other texturing tools without hand-separating maps or squarifying components. The GPL license and included documentation round it out for Blender users.
Decal Machine To Substance Painter, developed by Radu Coto, is a Blender add-on that converts decals or entire libraries of decals for use in other industry-standard texturing software. Rather than manually separating the ambient occlusion, curvature and height map, or squarifying each individual component by hand, DM2SP handles these steps with a couple of clicks.
Beyond conversion, the add-on assigns unique name identifiers and can append custom prefixes and suffixes to those names, alongside a few other useful tweaks. It relies on OpenCV for Python to do the heavy lifting, so the library needs to be installed for your system before use.
The add-on supports Blender 2.93, 3.0, 3.1 and 3.2 and is released under the GPL license. Installation follows the usual Blender procedure through Edit > Preferences > Add-Ons, and documentation is included. A demo video is also available.
Decal Machine To Substance Painter is best for blender artists using Decal Machine who want to convert decals or decal libraries for texturing software such as Substance Painter.
Decal Machine To Substance Painter is completely free to download and use.
Decal Machine To Substance Painter supports Blender 2.93, 3.0, 3.1 and 3.2, according to the developer's listing. If you are running one of these versions, the add-on installs through the usual path in Edit > Preferences > Add-Ons. For newer Blender releases not named here, check the developer's page to confirm current compatibility before installing, since only these versions are listed for the tool at this time.
Decal Machine To Substance Painter relies on OpenCV for Python to do the heavy lifting, so you need to install OpenCV for your system before using the add-on. The developer points to the opencv-python package on PyPI for this, and a detailed Windows installation walkthrough is provided in the add-on tutorial. Once OpenCV is in place, you can install and enable the add-on itself through Blender's preferences.
Decal Machine To Substance Painter installs through Blender's standard add-on procedure: open Edit > Preferences > Add-Ons > Install, pick the provided .zip file, then enable the add-on. Before that, install OpenCV for Python for your system, since the add-on depends on it. The developer links to the opencv-python package on PyPI and includes a detailed Windows installation guide in the add-on tutorial, and documentation is provided.
Decal Machine To Substance Painter is listed as free in this catalog, though licensing can change over time. The add-on is released under the GPL license. For current pricing and license terms, check the developer's page directly before downloading. If you plan to use it in a studio or commercial context, reviewing the GPL terms there is worthwhile so you know exactly what the license permits.
