Changing terrain size

[Canardia]

I need to expand a terrain from 1024*3 tiles to 4096*4 tiles, so that the old height data stays in the middle and only new flatland is added around it.

 

I tried to open the raw file with gimp, but it imports it always as 1024x512.

Why can't the terrain just be a simple DDS file?

 

The file size of the raw file seems also a bit wierd:

2097152 bytes, but it should be (1024)*(1024/8)*(4) (RGBA 8-bit) = 524288 bytes. As RGBA 16-bit it would be 1048576 bytes, so where does the double size come from?

not to hijack you, but can you even get the 4096*4 tile terrain to work in the first place? Does the collision work throughout the entire terrain? For me I fall right through around the edges of the terrain and I'd be interested if you've tried that size yet and tried the collision between the default controller in the editor and the terrain that is far from the center

@Pancakes: try SetWorldSize()

2097152 bytes, but it should be (1024)*(1024/8)*(4) (RGBA 8-bit) = 524288 bytes

The format of the terrain height data raw is single channel 16bit/ 2 byte (one entry for each gridpoint), so the file size IS correct

1024*1024*2 == 2097152

 

I don't know if your image editing program can load double precision single channel data. Can you set how to load the raw?

In Photoshop, there's this dialog and you'd need the following settings:
