Procedures

The main difference between the mr Physical Sky Parameters rollout described

here and the

mr Sky Parameters rollout on page 5176 on the command panel is

that this rollout lets you apply maps or shaders to the various parameters.

However, this version of the rollout isn't quite as accessible; you must use the

Material Editor to get at the controls.

To access the mr Physical Sky rollout:

1 Add an

mr Sky on page 5176 component to the Daylight system on page

5139 (and confirm the addition of the mr Physical Sky environment map),

or apply an mr Physical Sky shader as an environment map on page 6689

or in the Camera Shaders group of the

Camera Effects rollout on page

6283.

2 Open the Material Editor on page 5284 and choose a sample slot.

Click the Get Material button.

This opens the

Material/Map Browser dialog on page 5290.

4 On the Material/Map Browser, in the Browse From group on the left side,

choose Scene.

The Browser lists maps and materials in the scene.

5 Find the mr Physical Sky map and double-click it to load it into the active

sample slot.

You can now edit the shader parameters and apply maps and shaders on

the mr Physical Sky Parameters rollout.

TIP Alternatively, you can simply drag the map button from the Environment

panel or Camera Effects rollout to a sample slot in the Material Editor.
