|
| |
Name |
Displays the name of the selected environment. |
| |
Background Type |
Shows/hides the environment
image. Even when hiding an HDR environment image, the image still
radiates light into the project and reflects off shiny surfaces.
When you hide an environment image and a backplate, the background
color is defined by the Background Color
parameter in the Scenes tab. |
| |
Background Color |
Determines the background color of
the 3D Viewport outside the environment sphere. Click the color to
choose a new color. |
| |
Refract Background |
For objects with solid-transparent appearances,
refracts the background color or backplate instead of the
environment. See Rendering Solid-Transparent
Appearances for more details. |
| |
Brightness |
Sets the luminance. Higher values increase brightness;
lower values decrease it. Changes are made in real time. |
| |
Rotation |
Rotates the environment, which changes the direction
of light radiated by the environment image. Rotation is in degrees. |

Tone Mapping |
- Brightness. Sets the luminance. Higher values
increase brightness; lower values decrease it. Changes are
made in real time.
- Gamma. Sets the
contrast and brightness. Higher values decrease contrast and
increase brightness; lower values increase contrast and
decrease brightness. Changes are made in real time.

Transform |
- Flatten Floor. Flattens the floor of an
environmental sphere. HDR images are spherical by default,
with the equator corresponding to the imaginary level of the
floor. Flattening the floor converts the environment sphere
to a half-sphere. The image is remapped to the resulting
half-sphere and the bottom becomes a visible floor
- Flip Horizontal.
Flips the environment image horizontally (left/right) around
a vertical axis in the center of the image.
- Size (meters). Sets
the radius of the environmental sphere.
- Height (meters).
Vertically offsets the environment image relative to the
world origin.
- Rotation. Rotates the environment, which
changes the direction of light radiated by the environment
image. Rotation is in degrees.

Floor Effects |
- Caustics. Enables
advanced algorithms used to replicate the effects of focused
and reflected light through solid translucent objects or
reflective objects.
For example, a glass
of water sitting on a table often casts an interesting
pattern of light around the glass. These patterns of
focused light are called caustics.
-
Floor Caustics. Sets the level of
focused effects and reflected light on the artificial floor.
Floor Caustics affects the
reflected light with the Caustics
option enabled.
When the
Caustics option is enabled,
the Floor Caustics slider is
locked to the Floor Roughness and Floor Reflection
sliders. You can get the best visual result of Caustics
on the floor plane if you move all three sliders to
their maximum value. This functionality affects
performance.
-
Floor Reflection. Sets the level of
caustics from a physical light source on the artificial
floor.
Caustics are patches of intense
illumination caused by the refraction of light through a
transparent object or the reflection of light from a
reflective surface. An example is the shifting patterns
of light and shade cast on the floor of a swimming pool
on a sunny day.
- Floor Roughness.
Sets the level of shadows from physical light sources on the
artificial floor
-
Floor Shadow. Shows or hides shadows.
The software calculates the shadows that each 3D model casts
on itself, on other models, and on the floor. Showing
shadows can impact performance due to the increased number
of calculations required.
You can set the
floor shadow to form from spot or point lights only if a
floor plane is present.
- Shadow Intensity.
Lightens or darkens the environment floor shadow.

Preview Options |
Show Grid (In
Preview). Shows or hides a grid in the
XZ-plane. The grid is visible only when
Raytrace is off.

Transform |
The following transform options
let you numerically modify the lighting position:
- Position XYZ.
Translates the selected light in 3D space.
- Distance/Dolly.
Determines the distance between the selected light and the
look-at point.
- Longitude. Rotates
the selected light around the look-at point.
- Latitude. Moves the
selected light vertically.
- Twist. Tilts the
selected light left or right without moving its 3D
position.
You can also transform lights with the
transform manipulator.
