General

Interface options

Language: Chooses the language of Substance Painter. Please note that you will be invited to restart Substance Painter to take it into account.
Show keyboard helper: If enabled, displays the keyboard shortcuts at the bottom left of the viewports.
Show world axes: If enabled, shows the world axis in the bottom right of the 3D view.
Background color: Chooses the color of the gradient used as a background for the viewports.
Only display the selected material when painting: If enabled, only the Texture Set currently selected will be displayed when painting, hiding the other Texture Sets.
Default UV scale for materials: Define the default tilling value when creating a Fill Layer

Rotation speed: Multiplier of the default rotation speed of the viewport's camera.
Zoom speed: Multiplied of the default zoom speed viewport's camera (default zoom). Inverse direction allows to invert the direction of the zoom based on the mouse movement.
Wheel speed: Multiplied for the zoom speed of the mouse wheel (wheel zoom). Inverse direction allows to invert the direction of the zoom based on the wheel movement.

Save preprocessed scene files: If enabled, pre-processed high-poly meshes used by the bakers will be saved on disk for future re-use. This feature allow to re-bake more quickly.

Local cache directory: Define the location of where shelf thumbnails are located when generated.
Local cache budget (in MB): Define the maximum size of the cache.
Material preview shader: It is possible to select here the shader that will be used to generate the thumbnails of the shelf. This is usefull if the resources use a different workflow than the default PBR Metallic/Roughness. Please note that you will be invited to restart Substance Painter to take it into account.

Cache directory : Defines the location where Substance Painter writes temporary files (including the Sparse Textures cache).
Note : this settings can be overridden by an environment variable.

Hardware support acceleration : If enabled, Substance Painter will try to use the Sparse Textures feature of the GPU. For more details see the Sparse Virtual Textures page.
Note : this settings can be overridden by an environment variable.

This section lists all the compatible resource available that can be used when rendering with Iray.
The CPU setting is available on all the computers. If the computer has a Nvidia GPU with a version of CUDA compatible it will also be listed here. It is possible for example to disable the CPU and render only on the available GPU(s) (which is recommended).

Check for updates at startup : If enabled, Substance Painter will check for new versions when starting up. In case a new version is available, the Updater Checker window will open displaying additional information.

Automatically send usages statistics to Allegorithmic : If enabled, it will send information anonymously to Allegorithmic's servers about the computer hardware configuration along other usage data. These data help us improve the software.
