Material Library
In the Matter sidebar's 
library tab, the 
material library manages the groups of materials and the materials available in your database.
Groups of materials are listed in the upper part of the library:
Icon | Description |
|---|---|
| Create a new group. |
| Duplicate the selected group. |
| Rename the selected group. |
| Delete the selected group. |
Double-clicking on the material thumbnail makes it active and opens the materials editor.
Tip
To quickly locate the material in the library you can use the keyboard shortcut E when the mouse cursor is over a material. You can also use the shortcut Shift + E to directly open the materials editor.
The list of materials shows all of the existing materials in the selected group. Using the buttons below the list, you can:
Icon | Description |
|---|---|
| Create a new material. |
| Duplicate the selected material. |
| Edit the selected material by opening the Materials editor. |
| Rename the selected material. |
| Import materials. KMT and AxF formats are supported.KMT format is supported. NoteAxF file import (SVBRDF or CPA2 types) is subject to a license option. |
| Export selected materials in KMT format or AxF. |
| Delete the selected materials. |
| Purge materials that have not been used (materials that are not applied to any surface of any product). |
| Modify the way in which the list is displayed. |
Right-clicking on a material opens a context menu offering the following options:
Icon | Function | Description |
|---|---|---|
| Set active | Make the material you have clicked active and shows it in the lower part of the library. |
| Edit | Edit the selected material by opening the Materials editor. |
| Duplicate | Duplicate the selected material. |
| Convert to multilayer material | Convert the selected material(s) into equivalent multilayer materials. |
| Replace with | Replace the selected material(s) with another material from the material library. NoteThis functionality is available if at least two materials already exist in the material library. |
| Rename | Rename the selected material. |
| Usage list | Show a list of all products in which this material has been applied. |
| Import | Import materials. KMT and AxF formats are supported.KMT format is supported. NoteImporting the file AxF (SVBRDF or CPA2 type) is subject to license. |
| Export | Export the selected materials in KMT or AxF formats. |
| Delete | Delete the selected materials. |
The active material is shown in the lower part of the library:
Icon | Description |

Thumbnail | Double-clicking on the thumbnail opens the Materials editor. |
| Use the eyedropper to pick a material from a surface in a viewport and render it active. |
| Open the Materials editor for the active material. |
| Select the active material in the list of materials. |
AxF Material
AxF is a file format that encodes digital material representations, including those of materials measured using X-Rite material scanning technologies. Patchwork 3D supports version 1.9.0 of AxF files.
Note
Please note that AxF CarPaint (CPA2) type files can be exported in AXF format if they are not modified. If they are modified, only the export in KMT format is supported.
Warning
Overriding a material with an AXF type file consumes a lot of GPU and RAM memories.
You can change the base color of an AxF (CPA2) material from Matter by right-clicking on the surface that has an AxF material or from the Materials Library by right-clicking on the AxF material.
The parameters to be adjusted are as follows:
Hue Shift
Saturation
Exposure
Contrast
Note
Please note that these parameters are relative to the original color of the material. A saturation of 1, for example, corresponds to the original color of the AxF, if you decrease this value it decreases the saturation and if you increase this value it increases the saturation. The reasoning is the same for the other parameters.
