Values are displayed as float numbers between 0.0 and 1.0.


Values are expressed as a percentage between 0 and 100.

Temporary Editors

When performing certain operations, Blender will open a new window. The behavior of these operations can be configured here.

Render In

When rendering, the user interface can do any of:

Keep User Interface

The user interface does not change and the render is computed in the background.

Text Rendering

Animation Timeout

Length of animation when opening Pie Menus.

Tap Key Timeout

Keystrokes held longer than this will dismiss the menu on release (in 1/100ths of a second).

Recenter Timeout

The window system tries to keep the pie menu within the window borders. Pie menus will use the initial mouse position as center for this amount of time, measured in 1/100ths of a second. This allows for fast dragged selections.


The size of the Pie Menu set with the distance (in pixels) of the menu items from the center of the pie menu.


Distance from center before a selection can be made.
