Environment Lighting Override parameters

Environment light effect

Adjusts the effect of the environment light on the material. Enter any numeric value, or use the slider to make the effect of the light dimmer (0) or brighter (2).

Note

For a surface to receive Ray Tracing shadows, it must have some contribution from the Environment light in its Color parameter.

Colorize IBL

Click this radio button to tint the IBL environment light cast on the material. Click the swatch to change the color in the Color window (to find out about using this window, go to Change colors). To change the overall brightness of the color, use the slider.

IBL contrast

Changes the contrast of the lighting on the material (that is, makes the bright parts brighter and the dim parts dimmer). The default value is 1, and typical values range from 0 to 2.7. Enter any numeric value, or use the slider to make the contrast greater or lesser.
