Environment Probe
| Component entity system is in preview release and is subject to change. |
Use the Environment Probe component to achieve the right visual quality for a space. Environment probes help to determine proper reflections, ambient diffuse values, particle diffuse values, and shadow colors.
For information about how to blend environment probes to create a smooth transition, for example, from day to night, see Blending Environment Probes.
The Environment Probe component has the following settings:
- Visible
-
Shows the light.
- On initially
-
Specify if the light is on when created.
General Settings
See the following general settings:
- Color
-
The color of the light.
Default value: 0xFFFFFFFF
- Diffuse multiplier
-
Sets the strength of the diffuse color.
Default value: 1
- Specular multiplier
-
Sets the strength of the specular brightness.
Default value: 1
Environment Probe Settings
See the following environment probe settings:
- Area dimensions
-
The width, height, and depth in meters of the environment probe's effective area.
- Sort priority
-
Priority number for probe rendering. Lower priority numbers (for example,
0or1) are rendered on top of the higher priority numbers (for example,100).Default value: 0
- Resolution
-
Cubemap resolution in pixels that is generated by this probe.
Default value: 256
- Box projected
-
Enables box projection. Does not require regeneration of the cubemap.
- Box height
-
Height of the box projection.
- Box length
-
Length of the box projection.
- Box width
-
Width of the box projection.
- Attenuation falloff
-
The value that the light begins to falloff. For example, a value or 1.0 means the light starts to fall off at 1.0 meter.
Specify a value from
0.0to1.0.
Options
See the following options:
- View distance multiplier
-
Adjusts the maximum view distance. For example,
1.0uses the default and1.1is 10% farther than the default.Default value: 1
- Minimum spec
-
Minimum specular at which the light is enabled.
Default value: Low
- Voxel GI mode
-
Mode for light interaction with voxel global illumination (GI).
Default value: None
- Ignore vis areas
-
Light ignores vis areas.
- Indoor only
-
Light is only rendered indoors.
- Affects this area only
-
Light affects only the immediate area.
- Volumetric fog only
-
Light affects only volumetric fog.
- Volumetric fog
-
Light affects volumetric fog and surrounding area.
Animation
See the following animation settings:
- Style
-
Type a number to specify a preset light animation curve to play as defined in the
Light.cfxfile. Valid values are0to48. You can also use values40to48for testing and debugging.Default value: 0
- Speed
-
Multiple of the base animation rate. For example, a value of
2.0makes an animation play twice as fast.Default value: 1
- Phase
-
Animation start offset from
0to1. A value of0.1is 10% into the animation. For example, you can use this setting to prevent lights in the same scene, with the same animation, from being animated in unison.Default value: 0
Cubemap Generation
See the following cubemap generation settings:
- Cubemap
-
Click Generate to generate or regenerate a cubemap for this probe. The button is enabled only when Use customized cubemap is deselected.
- View cubemap
-
Displays a preview of the cubemap in the viewport. You can only select this option when a cubemap exists.
- Use customized cubemap
-
If selected, you can specify a custom cubemap for Cubemap asset. If deselected, a cubemap is generated.
- Cubemap asset
-
File path for the cubemap asset.
