New embroidery decal material
Inside the materials section of the Assets window you can find a new Embroidery decal materials. Drag and drop it anywhere over you mesh, plug in any resource (like a texture or even a font) and you will be able to easily create new fabric details.

New fill area color/mask filter
These two new filters allow to fill any closed paths or outlines. This is useful to quickly fill 3D paths for example. Because they are filters they can also be used for manual brush strokes or in other situations.

New FXAA filter
This new filter can quickly reduce the aliasing, especially on hard edges that can appear after a level for example or on masks made with the color selection effect.

New highpass filter
With this generic filter you can generate a grayscale texture to use it for more advanced effects (like softening, blurring or sharpening details).

New pixelate filter
The pixelate filter can simulate a reduction in resolution which can be useful to stylize colors and patterns.

New posterize filter
This filter can be useful to reduce the number of colors in an image which can help create contrasts in shapes and build stylized effects.

New threshold filter
The threshold filter is a quick way to create sharp binary black and white masks from a grayscale input.

New smoothstep filter
The smoothstep filter is another way of doing a level or contrast to refine grayscale information. This filter also applies an exponential curve to the result, making it possible to convert linear gradients into smooth curves.

Improved Transform and Mirror filters
The transform filter has been updated to support non-uniform scaling, flipping horizontally or vertically, and simpler to use parameters. The mirror filter has also been refreshed with more straightforward parameters.

Improved icons
To make standard filters more visible and easier to find, their icons have been remade. Icons tinted yellow are meant to be used on the content of a layer, while grayscale icons are generic and can be used both in layers content and mask.

Minor fixes on filters
A few other filters has been adjusted to fix some issues:

• The height adjust filter was affecting the alpha of a layer, making it difficult to use in some cases.
• The blur filter wasn't using a linear color space in Legacy color management mode, creating incorrect colors when blending/mixing its input.

Export textures with Adobe Standard Material in USD
When exporting textures from Painter into an USD file, you will now get the Adobe Standard Material properties with them. This make these USD files ready to be used into application that support those properties as well.

Import textures from USD files
Importing an USD file will now also import its texture in the project it creates, making back and forth between applications easier. If the USD file uses the Adobe Standard Material this will also configure the shader settings, making the result in the viewport match the other source application.

Gltf changes
Following the USD update, some change of behavior for the GLTF format were required to ensure parity. When importing a gltf file Painter will now presume that the normal map will be in OpenGL format.
Some gltf files may use the DirectX format instead. Therefore a new setting has been added in the new project window to take it into account (note that the normal format can also be overriden from the layer stack).

Updated dependencies
Several libraries used by Painter have been updated, notably to match the VFX platform reference. Here are the new versions used in Painter 10.1:

• Qt 6.5.6 (and PySide6 6.5.6)
• Substance Engine 9.1.3
• OpenEXR 3.2
• Python 3.11
• OCIO 2.3.2
• OpenSubdiv 3.6.0

Updated Linux support
This new version of Painter now supports Red Hat Enterprise Linux (RHEL) version 8.6 as the minimum, but should also be compatible with version 9.x.

Improved opening time of projects
Project that used a lot of brush strokes should now be faster to open in Painter. The saving time of these project should also be slightly improved.
In some of our test projects we observed a reduction from 50s to only 6s of loading time when opening a project. Memory consumption when opening old projects and converting them to the latest version has also been improved.

Improved tesselation performance
We now employ an automatic optimization when tesselation is enabled in the Shader settings. Triangle that are smaller than a pixel on screen will not be tesselated anymore, leading to less triangles to drawn and therefor faster rendering times.
This change doesn't produce visual differences and doesn't affect the mesh export process.

Simplified thumbnails are now the default
In version 6.2 we introduced the simplified thumbnails for UV Tiles projects to improve performance, but regular projects could still use the old way of computing layers thumbnails. This behavior was controlled via an application setting.
This setting now defaults to the optimized thumbnails by default to help performance on any projects. It can be reverted in the main preferences if desired.
