Logarithmic Exposure Control on page 6540 , making sure to turn on Affect
Indirect Only. The Brightness and Contrast controls of the exposure control
will only affect the radiosity solution and your lights will render as usual.
To process radiosity with standard lighting:
1 Ensure that your geometry is set to a physically correct scale.
2 On the Create panel, click Lights. Create and position
standard lights on page 4925 in your scene.
3 Click Render Scene to preview the lighting. At this stage, the
radiosity will not be processed, but you can quickly confirm that the
direct lighting is correct. Adjust the position of the lights if desired.
4 Choose Rendering > Advanced Lighting > Radiosity. Make sure that Active
is turned on.
5 On the Radiosity Parameters rollout, click Start to process radiosity. Once
the Radiosity calculation has been completed, you should see your results
in the viewports.
6 In the Interactive Tools group of the Radiosity Processing rollout, click
Setup to display the
Environment panel on page 6486 , where you set
exposure controls.
7 When working with non-physically based lights, always use the
Logarithmic Exposure Control on page 6540 . On the Logarithmic Exposure
Control rollout, select Affect Indirect Only. This will cause the exposure
control to affect only the results of the radiosity solution. By doing so,
you will maintain the way your direct lights render without radiosity.
Use the Brightness and Contrast controls of the exposure control to adjust
the intensity of the radiosity solution to match the lighting at an
appropriate level.
TIP You can use the thumbnail preview to adjust brightness and contrast
interactively.
