Terrain heightmap export-import

[diedir]

Hi Josh,

Do you plan exporting- importing heightmap terrain ?

It would be much (much...) easier to paint a 16.raw map with external software.

I need to reproduce real terrain, this feature would be a must!

thank you

You can import heightmap https://www.ultraengine.com/learn/Terrain_LoadHeightmap?lang=lua.

idk how to get a world in editor console to do it there tho.

In the editor: 

1. Create the Terrain with the specifc size eg: 512 * 512
2. Select the Terrain and choose the Terrain edit mode (the most left icon, where are also rotate and move controls)
3. In the right view you now have an open Terrain-Tab where you can load or save a heightmap.

If the heightmap is not visible there are some things to do.

1. The heightmap imported might not match the dimonsions you have created the terrain with.
2. If the scale is not high enough: 
   1. Got to the Map-Tab 
   2. Select the created Terrain
   3. Change the y-scale to something like 100.0 or 300.0 depending on your imported heightmap.

There is a Load button in the terrain panel. You must have a terrain selected for it to know which terrain to apply the heightmap to.

If you have any problems please upload the terrain heightmap you are using so I can try it.

So after trying a lot:

i made a terrain 2048 *2048 in editor and tried to import a

*.r16 file : the file is not present (hidden) in the dialog box explorer

*.raw file : file present in explorer dialog but result in failed to load in editor.

then with code (lua) no problem for each file: it loads  (though i think better result with r16 one)

don't know why in dialog explorer r16 is not seen

, so i put my file here (needed to rename extension because no allowed to upload *.r16 ), if you want to try (not a great elevation from 5m to 45m)
