Importing Heightmap wierd outcome.

Hi,

So I’m not sure if it’s the settings that I need to tweak on unity terrain or if it’s the settings in Gimp for my grayscale 8 bit heightmap

The issue is marked in the screenshot below:

I even tried to make a solid black square at the affected areas. Didn’t help.

Importing with:
Depth: 8 Bit (Only thing that worked)
Width & Height: 2500
Byte Order: Windows
Flip Vertical: Checked
Terrain Size: X: 1000 Y: 90 Z:1000
Screenshot of my setup in unity. (Nothing added except for the heightmap and Mesh Resolutions/Texture Resolutions.

Gimp Setup:

Thanks in advance!

Best of Regards,
Thomas

Found the major issue, It was the resolution of the images I had.
Only works with:
512 x 512
1024 x 1024
2048 x 2048
4096 x 4096
Which makes it fit with the Terrain and removes the ugly lines and such.
