 - Save terrain data immediately when assigning a new `data_directory` (attempt to workaround random saving issue #232)
 - Updated name detection in the texture import dialog to work better with AmbientCG and PolyHaven (thanks to GustJc)
 - Optimized `HTerrainDetailLayer` process function by updating chunks when needed and spreading calculations over time
-- Changed detail layers import settings so that texture format is `L8` (before it was intended to be `R8` but that is handled inefficiently by `save_png` and Godot's import pipeline)
+- Changed detail layers format to `L8`. Before it was `R8` but that is handled inefficiently by `save_png` and Godot's import pipeline. It kept using `RGB8` which consumed more memory and printed a "Will be converted" warning.
 - Fixed brush cursor looked off-center at close range when using tiny brush sizes
 - Fixed error when trying to change `TextureSet` mode while it has textures in it
 - Fixed shader parameters not displaying the right value in the inspector until they are set by the user at least once
