The Fix Ambient utility solves a compatibility problem that sometimes occurs when you use Autodesk VIZ to open files from earlier versions of Autodesk VIZor 3ds Max.
In Autodesk VIZ, the ambient and diffuse color channels are locked for standard materials. However, this was not always the case with earlier versions of Autodesk VIZand 3ds Max. As a result, files might render differently than expected.
The Fix Ambient utility looks for standard materials in the current scene whose ambient and diffuse colors are different, presenting you with the option to copy the diffuse color to the ambient color channel. This will ensure that your renderings are consistent with earlier versions of products.
Find All— The utility searches the entire scene for materials with different ambient and diffuse colors.
Find Selected— The utility searches the current selection for materials with different ambient and diffuse colors.
Help— Opens the help file to this topic.
This dialog appears after clicking Find All or Find Selected.
Status Message— This area displays a message indicating whether your scene (or selection) has materials with different ambient and diffuse values.
Material List— Lists all of the materials with different ambient and diffuse values.
Fix Selected— Locks the ambient and diffuse channel for the materials selected in the dialog.
