the method you’re trying to import height map has problems and gives you no control, I would suggest importing any of “height maps” from asset library, then changing the map by selecting on it, this way you have full control, including scale, rotation, etc.
Thanks! This worked (but is also rotated 90°)
But i still think this is a bug that should be changed. UP in a height map should be north in the 3D environment.
We tested it using the terrain map image you provided. Currently, it is expected for terrain maps and assets to follow a default direction. However, we will take your suggestion into consideration for future updates. Thank you for your valuable feedback!
