Heightmap not loading properly into 4km

[ismaelassassin]

Hello
Im trying to work on a map but when i load the RAW file it gives me 6303750 != 2101250 ((1025x1025x4)*1,5) != (1025x1025x2) and the geometry is all a mess.

The photshop file of the heightmap has 1025x1025 size and saved as IBM PC.
the map was created with 1024 size and scale 4.

Please i want to get working on this but i have no idea why its giving me this problem.

Wrong format. Did you edit the heightmap in Photoshop?

[ismaelassassin]

Yeah. i saved it as RAW and choose IBM PC option

And what settings did you use to open it?

[ismaelassassin]

i created a new file of 1025 x 1025 and edited it with pics of heightmaps. There was nothing before.

You should open an existing heightmap with correct settings, edit it and then save. At least that's the way I know to edit and save heightmaps successfully.

Uhh guess ill try that. Although, i had trouble trying to open heightmaps in photoshop. When i open something like yamalia all i can see is a mess of black and white pixels as if its TV static. Would it still work when i try to modify it and saving it?

When I open I get a prompt on what settings to open with

AFAIK secondary terrain should be 8bit depth and resolution+1 (ex. 257x257 and not 256x256).

For primary it's 16bit IBM PC depth and resolution+1 (ex. 1025x1025 and not 1024x1024).

No, secondary is 257*257

Lol. Hey! it worked! something weird happened where the heightmap was inverted. but it worked!
Thanks for the help!

inverted heightmap is expected. It is always that way

No, secondary is 257*257

Oops, correct.

[Outlawz7]

Heightmaps are inverted on the vertical axis.
