Did someone break import of terrain from old assets?
I’m talking about the time when layer maps were embedded into terrain.
I have run into an old asset where terrain is imported untextured, but there’s foliage. Trying to figure out if it was designed like that or if it is a bug.
Probably the quickest way would be to just install the Unity version the asset was designed/uploaded using, or Unity 2018.2.21 (last version before the terrain redesign) and try the asset there.
