Can't import heightmaps. Map Generation Failed.

[Rick Locker]

I'm trying to import heightmaps into the map editor to make some custom maps but all of the images I try get errors.

I have 13 images. All in grayscale, all of them heightmaps. I try to use any of them and I get an error: Map Generation Failed: Internal error (see console for details).

I check the console and I get this:

Exception type: struct heightmap_util::ImportException

Details:

Error message: Image type must be grayscale.

Minidump: C:/Program Files (x86)/Steam/userdata/95634119/1066780/local/crash_dump/39cb4f00-aecf-4891-8d33-a62c817df6e3.dmp

In file: c:\build\tpf2_steam\src\game\terrain\heightmap_util.cpp:51

In function: class std::vector<float,class std::allocator<float> > __cdecl heightmap_util::ReadHeightmap(const class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > &,float,float,int *,int *)

All of these heightmaps are in grayscale so I don't know why the game thinks they're not.

Can anyone help me with this? I just want to make some maps.

I have a sneaky feeling the images are not true grayscale. To make sure, I would import the heightmap into GIMP, convert them here to 16 bit grayscale and then export the file selecting 16 bit grayscale again, and if I remember right, it needs to be a BMP file.
Hope this helps.

This has been a fantastic place to get heightmaps:

https://tangrams.github.io/heightmapper

You can then use Gimp:

https://www.gimp.org/

To edit the image and under Image > Mode change the Precision to 16-bit (from 8-bit) and the Color to Grayscale.

Then save it to PNG and when it has the option to pick which specific format change it from Automatic to grayscale 16bpp.

I used GIMP and changed the precision to 16bit and set the color to grayscale, extracted a copy in .PNG format and set it to grayscale 16bpp then placed it in the 1066780 folder but when i go into the map editor there's nothing on the list that i can import. Any ideas?

the grayscale image must be in "/Steam/userdata/<steam_id>/1066780/local/heighmaps" as the import screen tells you

Sorry, I forgot to state that other folder step. It is in the heightmaps under 1066780/local

I watched a youtube video that went step by step how to do it exactly as SoopaMan's post describes but it still doesn't show up in editor.
