Substance 3D Painter 12.2 introduces cage painting, smarter Polygon Fill selections, texture-set highlighting, and improved real-time rendering for overlapping transparent materials.

Adobe has released Substance 3D Painter 12.2, introducing several workflow improvements intended to reduce the repetitive setup, selection, and troubleshooting involved in texturing detailed 3D assets.

The update’s biggest addition is cage painting, which gives artists more direct control over projection distances during baking. Painter uses a cage to determine how far it should search beyond a low-poly mesh when capturing detail from its high-resolution counterpart. A cage that is too close can miss details, while one that extends too far can capture information from unintended surfaces.

Artists can now paint the cage distance directly onto their model with per-pixel brush control or use Polygon Fill to adjust complete sub-objects. This should make it easier to identify and correct local projection problems before committing to another bake instead of repeatedly changing the entire cage and checking the result.

Adobe Substance 3D Painter 12.2 Features

The feature continues Adobe’s recent effort to make Painter’s baking workflow more interactive. Version 12.1 introduced automatic rebaking and the ability to paint skew corrections directly onto low-poly geometry. Cage painting now applies a similar visual workflow to another common source of baking artifacts.

Polygon Fill has also received three selection modes. Rectangular Marquee allows artists to drag across a chosen area, Polygon Loop selects a continuous loop of faces, and Partial Polygon Loop targets a smaller portion when a complete loop would include too much geometry.

A new Visible Polygons Only option prevents rectangular selections from passing through the model and affecting polygons on its opposite side. This seemingly small addition addresses a persistent frustration when masking geometry in the 3D viewport, particularly on dense meshes or assets containing overlapping parts.

Painter 12.2 also introduces Texture Set Highlighting. Hovering over a texture set illuminates its corresponding geometry in the viewport, while holding Ctrl/Cmd + Alt and hovering over the model identifies which set contains that part. The feature should be especially helpful when opening unfamiliar projects or navigating characters and props divided across numerous materials.

Finally, Order Independent Transparency improves the viewport rendering of glass, ice, liquids, and other low-opacity materials. When several transparent surfaces overlap, Painter can now sort them more accurately, producing a clearer real-time preview of their intended appearance.

Substance 3D Painter 12.2 is available now. Adobe’s full technical breakdown and list of fixes can be found in the official release notes. Readers can also revisit 80 Level’s interview on Substance 3D Painter’s role in modern production pipelines and the additions introduced with version 12.0.
