Heightmap import persisting error

[viridis]

Hi, I am trying to learn how to import heightmaps in order to collaborate with mapmaking, but find an error after importing the file. It is:

• BMP format
• 128x128 px
• 8 bit gray-depth but RGB color mode

I am using Linux x64 and 0ad version Pyrogenesis 0.0.21

After some time working, the editor opens a window with the following error:

Function call failed: return value was -120102 (Invalid/unsupported texture format)
Location: tex.cpp:124 (tex_validate_plain_format)

Call stack:

errno = 0 (No error reported here)
OS error = ?

Any ideas? could you try my image and tell me if you are able to generate a map with it?

I have attached both the BMP and the original image file.

As the error says, BMP format (with these settings) is not supported, you need to use BMP with right settings, the one of:

1. gray, 8 bits per pixel without alpha channel
2. colored, 24 bits per pixel without alpha channel
3. colored, 32 bits per pixel with alpha channel

About required format: https://trac.wildfiregames.com/wiki/Atlas_Manual_Heightmap_Import

UPD. Your BMP hasn't a gray flag (in other words it's colored), but it has 8 bits per pixel.
