In the KeyShot Library’s Material tab you can find a number of material presets, that you can apply to your model.
The material presets you see are all created using a KeyShot Material Type. Each library material has been designed to be easy to use with as few parameters as needed. For example, the Metal library materials use the Metal material type and will only display the parameters needed for metal materials. Likewise, the Plastic library materials use the Plastic material type will have only the parameters needed for plastic materials.

The installer contains high-quality materials with textures from Poliigon that have been excluded form the regular Keyshot installer because of their size. The Poliigon textures used for the materials in the installer can only be used inside KeyShot, if you need the textures for other purposes, visit the Poliigon Textured Materials page for a list of textures used.
Download the installer here:
Content Installation
After downloading, run the installer. During installation, the new resources will be added to your KeyShot Resource folder and visible in the KeyShot library, Materials tab next time KeyShot is launched. The new Poliigon folder will be added to your Materials folder.
Note
The materials in the Installer are the same as offered in the Content installer for KeyShot 9, KeyShot 10 and KeyShot 11 but they have been updated to take full advantage of the improvements to KeyShot 2023.1 materials.
If you installed the Poliigon material pack in KeyShot 9/10/11 and chose to migrate your resources to KeyShot 2023.1. The Poliigon materials will only be overwritten with the new version, if the folder has been moved from the migration folder to the root of the Material library at the time you install the KeyShot 2023.1 Content pack – Otherwise you will have 2 versions of the “same” material.
