@fabrizio520 Unfortunately, the manual is only in german, so i try to give you a short summary of the steps:
- You have to copy the files from the folder "Vegetation" into your root directory of the train simulatior.
- You have to install the three Asset-Packs mentioned in the manual (the links are in the manual, blue font).
- If you own the Mosel-Valley-Addon, you can copy the files from the "Mosel"-folder into your train simulator directory as well. This will place trees from that addon to the route.
That's it. Hope i could help you.
