Show Environment Image |
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. |
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 re-mapped to the resulting half-sphere and the bottom becomes a visible floor. |
Background Color |
Determines the background color of the 3D Viewport
outside the environment sphere. Click the color to choose a new color. |
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. |
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, thereby changing the direction of light radiated by the environment image. Rotation is in degrees. |
Flip Horizontal |
Flips the environment image horizontally (left/right)
around a vertical axis in the center of the image. |
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. |
Show Grid (In Preview) |
Shows or hides a grid in the XZ-plane. The grid is visible
only when Raytrace is off.
