For those of you crashing after the 1.15.0.0 game update, unzip FS25_Ray_County.zip and replace FS25_Ray_County\config\terrainShader.xml with the one from C:\Program Files (x86)\Steam\steamapps\common\Farming Simulator 25\data\shaders\terrainShader.xml (or where ever your base game files are. Rezip it and delete the folder. This should hopefully get you by until the No Creek Farms has a chance to fix the file.
