Scene Properties

Scene

Properties ‣ Scene ‣ Scene

Camera

Used to select which camera is used as the active camera. You can also set the active camera in the 3D Viewport with Ctrl-Numpad0.

Background Scene

Allows you to use a scene as a background, this is typically useful when you want to focus on animating the foreground for example, without background elements getting in the way.

This scene can have its own animation, physics simulations, etc, but you will have to select it from the Scene data-block menu, if you want to edit any of its contents.

Background Scenes can themselves have a Background Scene (they’re recursively included). So you can always make additions to existing scenes by using them as a background to a newly created scene where your additions are made.

Nasvet

This can also be used in combination with Linking to a Scene, where one blend-file contains the environment, which can be reused in many places.

Active Clip

Selects a Movie Clip that can be used by Motion Tracking Constraints or a camera’s Background Images.

Units

Properties ‣ Scene ‣ Units

Unit System

The unit system to use for user interface controls.

None

Use units that have with no relation to the real world, practically this is the same as Metric just without unit names.

Metric

Use the metric unit system in this scene.

Imperial

Use the imperial unit system in this scene.

Unit Scale

Scale factor to use when converting between internal units and values displayed in the user interface. This can be changed when modeling at microscopic or astronomical scales.

Opomba

This only influences the values displayed in the user interface and not how things behave internally. For example, physics simulations don’t take the unit scale into account.

Separate Units

When using Metric or Imperial, display properties as multiple values. For example, 2.285m will become 2m 28.5cm.

Rotation

Unit to use for displaying/editing rotation values.

Degrees

Use degrees for angles in the user interface.

Radians

Use radians for angles in the user interface.

Length

Unit that will be used to display length values.

Adaptive

The unit used for a specific value depends on the magnitude of the value. For example, some values might be displayed as 23cm while others are displayed as 10km.

Meters/Centimeters/Feet

A fixed unit that will be used for all lengths in the user interface.

Mass

See Length.

Time

See Length.

Temperature

See Length.

Properties ‣ Scene ‣ Gravity

Audio

Sklic

Podokno

Properties ‣ Scene ‣ Audio

Options to control global audio settings. To control how sounds is played back from within Blender, see the audio settings in the Preferences.

Volume

Volume for the scene.

Distance Model

Changes how the sound attenuation is calculated based on the distance. Most physically correct is the Inverse model, but it’s also possible to choose a linear and an exponential falloff. The clamped modes limit the volume to be lower than 100% (1.0), that means if the distance is smaller than the reference distance, the volume is always 100%. For an exact description of each option see the OpenAL documentation.

Doppler Speed

Speed of the sound for the Doppler effect calculations. The typical value is 343.3 m/s in air, in water for example this value is around 1560 m/s.

Doppler Factor

Controls how strong the Doppler effect is. You can exaggerate or attenuate the change of pitch, but physically correct is a factor of 1.0.

Update Animation Cache

Updates the audio animation cache. This is useful if you start noticing artifact in the audio.

Properties ‣ Scene ‣ Rigid Body World

The Rigid Body World is a group of rigid body objects, which holds settings that apply to all rigid bodies in this simulation.

See Rigid Body World for more information.
