Unity Terrain Texture Resolutions

Hello everyone,

Why is that in Unity the heightmaps are of width and height of power of 2 + 1 not powers of 2. Also, how does this correspond to alphamaps which are just powers of 2, i.e. if I am generating an alphamap and heightmap procedurally in a script, how do the mapped values correspond since they aren’t of equal dimensions?

If you are talking about the import heightmap feature its because its in RAW format which adds an extra pixel. So a 1024x1024 heightmap is 1025x1025 in RAW format.
