How to import heightmaps?

the Terrains Menu does not shown in my unity and i want to import heightmaps ? ? ?

If you are using a newer version of Unity, you should be able to import a heightmap by:

  1. clicking on your terrain in the hirachy
  2. expanding the item labeled “Terrain (Script)”
  3. Click on the gear icon (Settings)
  4. Scroll to the bottom
  5. Two buttons are here, click import raw
  6. import heightmap
  7. Smile, problem solved :smiley:

Did you try the manual?

Unity provides the option to import and export heightmaps for a terrain; if you click on the Settings tool (the rightmost button in the toolbar) you will find buttons labelled Import RAW and Export RAW.
