Still having problems with terrains

Hi,

Using the terrain demo terrain-heightmap image which is a 256x256 BMP file everything is fine but when I try to use any other size it doesn't work, i.e if I simply resize the image to 512 by 512 or use the earthbump.bmp image which is 512x256 I get a really screwy looking strip with separate layers.

I am using version 1.0 of Irrlicht on an Intel Mac and all the demos work fine but I really want to use it with bigger terrain files (i.e I really want to generate them using terragen @ 1024x1024 and import them) or possibly find a way to stitch together many small ones.

Can anyone help me?

Cheers,
Chris

Only terrain size of 129x129 works correctly in all aspects. This is due to Irrlicht's index buffer and the terrain implementation. This is a known limitation and is currently being worked on.

Well that explains a lot.

Can anyone explain how to stitch together small terrains to make one large one?

A simple to follow code example would be appreciated.

Cheers,
Chris

You could patch Irrlicht to use 32 bit indices, but this patch does only work on Irrlicht 1.0, I guess... That's the way I did it.

Have you got the patch, I am using 1.0.
