Download multipart RAR archive from Customer Area > Downloads page. You need to download all parts of archive (If it is a split archive) to be able to begin the unpacking process.
For unpacking of archive you can use WinRAR or other compatible software. If you have downloaded all files needed, and placed them in the same directory, it is sufficient to double-click the file with the extension “.part01.rar” to start the unrar process (First part only! All other parts will be found and extracted automatically!).
Copy or leave the unzipped Mat-Pack-xxxx-x-x-R25 database directory on any disk partition with more space (can be a network drive). For faster reading of the database, we recommend an SSD drive (optional).
Start Cinema 4D and go to the Assets Browser Preferences.
Click on the “Add Folder…” button and point to the Mat-Pack-xxxx-x-x-R25 database directory that has been unzipped and saved on disk.
The database will be mounted and available in the Assets Browser.
