Hi, I am having a problem with using heightmaps in DB Pro, well actually the heightmap isn't the problem, but the texture is. Whenever I texture the heightmap the texture tiles itself over the heightmap instead of spreading accross the whole map. The heightmap and texture are both in bmp format and are both 1024*1024. A pic is attached. Please help, thanks.

Don't look behind you.

Well actually these heightmaps arn't going well, I am having a few problems with them:

1: The terrain from the heightmap seems to have no polies, like berore I made the terrain I had the same amount of polies as when it was made. The statistic(1) shows the same amount!

2: The texture from the heightmap isn't working properly.

Please if you have any ideas then I'll be very happy to hear them, thanks.

AT works only with true color grayscale heightmaps
Probably your heightmap is not a 24bit image

Well I changed the heightmap to 24 bit and it didn't make any diference. I don't know how to change to truecolor greyscale. If anyone can give me any help please do, thanks.
And thanks scorpyo for your input.

Here is a pic of the heightmap, its 24 bit.
The terrain collision is also messed up, I am using this code for it:


This collision code isn't working properly, if anyone can see a problem with it please let me know.

ahhh you are using the old terrain commands, not Advanced Terrain !
that is a known bug. old terrain doesn't work properly, I can't remember well but i think it started tiling beyond 128x128 heightmap sizes.

for Advanced Terrain the command is:
get terrain ground height(terrain number,object position x(1), object position z(1))

try this AT example and see if it runs on your DBP version

There is a problem with setting the heightmap, whenever I use this code:


When I run this code I get a crash document which says:
m_dwRuntimeErrorDWORD=7007
m_dwRuntimeErrorLineDWORD=62

Can anybody help me here?

Edit: I fixed this problem thanks everyone for the help, escpecially Scorpyo, thanks.

For the record - the detail map is like a texture - I've only seen gray ones - that are tiled every where - but do not have color - think of it as the "rocks" on your dirt texture (or grass). Check out the Advanced terrain samples that come in the download for advanced terrain. I copied that code verbatum until I understood what each command was doing.
