The Autodesk Material Libraries are shared libraries installed with Autodesk products such as Autodesk Inventor, Autodesk AutoCAD, Autodesk Revit and 3ds Max.
The Material Libraries are installed by default (unless you deselect the option) when you install 3ds Max. If one of the other applications is already installed, the material libraries might be installed already.
This library contains the material appearances used for Realistic Appearance in color styles. It is installed by default, and it is required for 3ds Max to have full visual style and color style functionality.
This library contains low-resolution (approximately 512 x 512) images for use with Autodesk Materials.
This library contains medium-resolution (approximately 1024 x 1024) images for rendering materials in medium detail. This library is used for close-ups and for rendering objects at a larger scale. This library is an installation option available on the Select Products to Install page in the installation wizard.
To reinstall the material libraries, run the corresponding MSI:
