Getting Error Trying To Create Landscape

I've imported my .hgt file to unreal but when I to click "Create Landscape(s) it throws me an error "Unable to save package to ../../Content/Core/Assets/FrontendLevel.umap because the file is read-only!"

I've trying making another plugin but it does the same thing. please help me understand what i'm doing wrong

 

Have you created a new route? Take a look at this tutorial from around 12min 40 sec.



You don’t need to have the lidar data to create the tiles, the SRTM data is fine to get started.

 

Thank, It fixed it
