Substance 3D Painter 12.2 Is Out: Cage Painting and Selection Tools Updated

Adobe released Substance 3D Painter 12.2 on 21 October 2026. The update includes changes that give artists more direct control over bake settings, geometry selection, and material previews while texturing detailed 3D assets. According to 80 Level, the release is available now.

Local control over the bake cage

The headline addition is the ability to paint the distance of the bake cage directly on the model. Painter uses the cage to transfer details from a high-resolution model to low-poly geometry. Whether the cage sits close to or far from the surface can affect how accurately details are captured: an unsuitable distance may cause information to be missed or unwanted surfaces to be included in the bake.

In 12.2, artists can adjust the cage distance with a brush at the pixel level. Alternatively, Polygon Fill can be used to edit across entire sub-objects. This makes it possible to change settings locally in problem areas, reducing the need to adjust the entire cage each time and recheck the bake from scratch.

This improvement follows earlier changes that made baking in Painter more interactive. According to 80 Level, version 12.1 introduced automatic rebaking and the ability to paint skew corrections on low-poly geometry.

Finding Polygon Fill selections and texture sets

Polygon Fill gains three new selection modes. Rectangular Marquee selects a rectangular area defined by dragging. Polygon Loop selects a continuous face loop, while Partial Polygon Loop lets artists select a smaller section when a full loop would be too broad.

The Visible Polygons Only option prevents rectangular selections from reaching polygons on the back of the model. This control can help limit the selection on assets with dense geometry or overlapping parts.

Texture Set Highlighting also makes it easier to see which parts of a project belong to which texture sets. Hovering over a texture set highlights its associated geometry in the viewport. To check which set a part of the model belongs to, hold Ctrl/Cmd + Alt while hovering over it. This can be useful for characters and objects split across many materials, as well as projects originally set up by someone else.

Real-time display of transparent surfaces

Order Independent Transparency handles draw order in the viewport more accurately when multiple transparent surfaces overlap. 80 Level lists glass, ice, and liquids as examples that could benefit from the improvement. The aim is to make real-time previews of these materials in Painter easier to interpret.

Impact on architecture and archviz workflows

The new features in Painter 12.2 are not direct architectural modeling or final rendering features; they target texturing and asset preparation. Architectural visualization teams can use these tools to fix local projection issues during baking and identify relevant geometry in models with many texture sets. Artists working with transparent materials such as glass may also find overlapping surfaces easier to read in the application’s preview.

The update announcement does not provide pricing, licensing terms, hardware requirements, or compatibility details. As a result, it is not possible to make a definitive assessment of how the new version will affect existing workstations or team licenses. Before switching, checking bake results, texture set selections, and transparent material appearance in production files can help determine whether the changes suit the workflow.
