Download the compressed file and extract its contents using a program like 7-Zip or WinRAR.
Drag the extracted Texture folder directly into your OMSI 2 root directory. Merge when prompted.
Copy the folders (usually Sceneryobjects and Splines ) into your main OMSI 2 directory, typically located at: C:\Program Files (x86)\Steam\steamapps\common\OMSI 2\
While we cannot host the file directly here due to copyright policies of original mappers (often Patrick or KissFM user group), the authenticated link is located on the OMSI 2 WebDisk (webdisk.omsi.de) or the official Steam Workshop .
