The Lightscape material lets you set radiosity behavior for 3ds Max materials you want to use in existing Lightscape radiosity meshes.
Note: This material is for use with Lightscape. It is not meant for use with the advanced lighting solution in 3ds Max. For adjusting a material's radiosity properties in 3ds Max, use the Advanced Lighting Override material.
Important: The mental ray renderer does not support the Lightscape material.
Brightness—Controls the brightness of the displayed image on your monitor. The setting of this control does not affect the actual lighting levels in the model. Note: The default value is exactly the same as the values set in the Import Lightscape Solution dialog.
Contrast—Controls the contrast between light and dark regions in the model. Note: The default value is exactly the same as the values set in the Import Lightscape Solution dialog.
Ambient Light—Controls the amount of 3ds Max ambient light that will be mixed in with the radiosity calculations. If the value is 0, none of the 3ds Max ambient light is used. If the value is 1, the 3ds Max ambient light value is added into the radiosity calculations. Default=0.0.
Bump Amount—This value controls the strength of the bump map that is applied to the lighting from Lightscape, as opposed to lighting done by 3ds Max. It can be separately controlled from the bump amount in the 3ds Max material, so you can adjust the bumps in Lightscape lighting to match the bumps in 3ds Max lighting. Default=5.0.
Daylight—Determines whether you want natural daylight to be used in the calculation. Note: The default value is exactly the same as the values set in the Import Lightscape Solution dialog.
Exterior Scene—Used for exterior daylight simulations. Note: The default value is exactly the same as the values set in the Import Lightscape Solution dialog.
Apply Changes to All Lightscape Materials—Determines whether or not the changes you make in this dialog are applied to every Lightscape Radiosity material. Default=off.
Disable Radiosity—Determines whether or not the radiosity is calculated. This option provides a quick way to see the effect of the Lightscape-specific illumination. Default-off.
