Lighting Analysis Assistant (3ds Max Design)
 
 
 
Command entry:Lighting Analysis menu Lighting Analysis Assistant

The Lighting Analysis Assistant is a dialog that helps you coordinate and adjust the various tools that 3ds Max provides to help you analyze the lighting of a scene. With the Lighting Analysis Assistant, you can discover what tools you need, and correct their settings to achieve an accurate lighting simulation.

ImportantThe Lighting Analysis Assistant requires you to use the mental ray Renderer and mental ray materials with physically correct settings.

The Lighting Analysis Assistant coordinates these tools:

WarningThe Lighting Analysis Assistant does not guarantee a correct lighting simulation. It can detect discrepancies among the tool settings that are required for lighting analysis, but in addition, you must judge the results based on the size of your scene, the number of lights, and other real-world factors.

For more information about creating and analyzing an accurate lighting simulation, we recommend you read these white papers:

Main caption

The main caption contains a reminder of the purpose of the dialog: “Create, edit and review Lighting Analysis tools.”

It also reminds you about the workflow of this dialog: “Invalid Settings are shown in bold: correct these settings, then click Update Status to confirm your corrections.” Each panel of the Assistant can show whether there are invalid settings in your scene: these appear in bold, and the Assistant helps you correct them. However, the analysis display is not interactive: after you correct settings, you must click Update Status to see the results of the corrections you made.

Lighting Analysis panels

The four panels in this dialog show the current state of your lighting analysis tools, and provide ways to adjust these settings.

Each panel is described in one of the topics that follow.

Status

The status shows the number of invalid settings the Lighting Analysis Assistant has detected. This value is updated when you click Update Status. When the number of “Invalid Settings” equals zero, you can render the scene with some confidence that light levels will be true to life.

Update Status

Click to update the status and incorporate adjustments you have made to the lighting-analysis tools.

When you click Update Status, invalid settings indicated by bold text might turn to regular text. In addition, the number of “Invalid Settings” shown in the Status field can change. When “Invalid Settings” equals zero, you can go on to render your scene.
