Lighting Analysis

Select an object that has radiosity solution information. > Rendering menu >

Advanced Lighting > Lighting Analysis

To query light levels, analyze the data, and produce reports, use the Lighting

Analysis dialog. This dialog provides rendering data on material reflectance,

transmittance, and luminance.

For example, a lighting engineer might need to know if light fixtures in a

scene provide an even level of illumination on the walls of a building. The

engineer uses the Lighting Analysis dialog after placing the lights in the ceiling

and processing radiosity. The engineer inspects the light levels and material

reflectance in the scene and then adjusts the brightness of lights, changes

units, or reduces material reflectance.

To use the Lighting Analysis tools, a radiosity solution must be calculated and

displayed in the scene. For better feedback, use it in conjunction with the

Pseudo Color Exposure Control on page 6552 . This tool maps luminances or

illuminances to pseudo colors that show the brightness of the values 3ds Max

converts.

TIP You can also export LogLUV TIFF files on page 7164 or PIC files on page 7151

for analysis by other software; do this by using the

Lighting Data Exporter utility

on page 6559 .
