Scene Properties¶

Scene¶

Reference

Panel:	Properties editor ‣ Scene ‣ Scene

Camera: Used to select which camera is used as the active camera. You can also set the active camera in the 3D View with Ctrl-0.

Background

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.

Sets can themselves have a background set (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.

Tip

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

Active movie clip for constraints and viewport drawing.

Units¶

Reference

Panel:	Properties editor ‣ Scene ‣ Units

Length Presets

Common unit scales to use.

Length

None: Uses Blender Units.
Metric, Imperial: Standard unit of measurement for lengths.

Angle

Standard unit for angular measurement.

Degrees, Radians

Tip

When you are using Degrees, the radian value is also displayed in the tooltip.

Unit Scale

Scale factor to use when converting between Blender Units and Metric/Imperial.

Tip

Usually you will want to use the Length presets to change to scale factor, as this does not require looking up values to use for conversion.

Separate Units

When Metric or Imperial display units as multiple values, for example, “2.285m” will become “2m 28.5cm”.

Imperial Units¶
Full Name	Short Name(s)	Scale of a Meter
thou	`mil`	0.0000254
inch	`"`, `in`	0.0254
foot, feet	`'`, `ft`	0.3048
yard	`yd`	0.9144
chain	`ch`	20.1168
furlong	`fur`	201.168
mile	`mi`, `m`	1609.344

Metric Units¶
Full Name	Short Name(s)	Scale of a Meter
micrometer	`um`	0.000001
millimeter	`mm`	0.001
centimeter	`cm`	0.01
decimeter	`dm`	0.1
meter	`m`	1.0
dekameter	`dam`	10.0
hectometer	`hm`	100.0
kilometer	`km`	1000.0

Keying Sets¶

Color Management¶

Reference

Panel:	Properties editor ‣ Scene ‣ Color Management

Options to control how images appear on the screen.

For Color Management settings for more information.

Audio¶

Reference

Panel:	Properties editor ‣ Scene ‣ Audio

Options to control global audio settings.

Volume: Volume for the scene.
Update Animation Cache: Updates the audio animation cache. This is useful if you start noticing artifact in the audio.

Distance Model¶

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.
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: 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.

Format¶

These settings, along with the settings found in the Encoding Panel change how sound is exported while rendering.

To control how sounds plays back from within Blender, see the audio settings in the User Preferences.

Channels: Sets the audio channel count. Available options are: Mono, Stereo, 4 Channels, 5.1 Surround, 7.1 Surround.
Mix Rate: Sets the audio sampling rate.

Gravity¶

Reference

Panel:	Properties editor ‣ Scene ‣ Gravity

Options to control global gravity used for physics effects.

See the Physics chapter for more information.

Rigid Body World¶

Reference

Panel:	Properties editor ‣ 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.

Simplify¶

Reference

Panel:	Properties editor ‣ Scene ‣ Simplify

Subdivision: Maximum number of Viewport/Render subdivisions to use for the Subdivision Modifier.
Child Particles: Percentage of Child Particles to see in the Viewport/Render.
