Every time I make a terrain it works fine, but then when I save it, and reopen it it always has missing textures and assets!!!! What am I doing wrong??!!! I even look in the levels folder! 3 terrains with hours of hard work have vanished because of this.
Never mind, this was before I watched mecke96's tutorials. I did not change the folder paths in the material.cs files and did not set up the folders correctly.
After renaming all the files and the folder be sure to check these files and fix paths: materials.cs (many of these) whatever_your_level_is_called.mis info.json managedItemData.cs
