How can I scale my terrain? it is too small here is my code...

dbLoadImage ( "map1.jpg", 1 );
dbLoadImage ( "detail.jpg", 2 );
dbSetupTerrain ( );
dbMakeObjectTerrain ( 1 );
dbSetTerrainHeightMap ( 1, "map1_HM8.bmp" );
dbSetTerrainScale ( 1, 2.0f, 0.6f, 2.0f );
dbSetTerrainLight ( 1, 1.0f, -0.25f, 0.0f, 1.0f, 1.0f,0.78f,0.5f );
dbSetTerrainTexture ( 1, 1, 2 );
dbBuildTerrain ( 1 );

You just need to change this values

dbSetTerrainScale ( 1, 2.0f, 0.6f, 2.0f );

this the way everything is set up

dbSetTerrainScale ( ID #, X, Y, Z );

just icrease the X and Z coordenates to make it larger, do not increase Y since you dont want your terrain to be too thick.

set dbSetTerrainScale to ( 1, 3.0f, 0.9f, 3.0f ); And if its still not big enough just increase the last 3 numbers.

I would personally do it like this:

float scaleWidth = 1.0f, scaleHeight = 0.3f, scaleDepth = 1.0f;
float terrainSize = 5.0f;
dbSetTerrainScale( 1, scaleWidth * terrainSize, scaleHeight * terrainSize, scaleDepth * terrainSize );

You change terrainSize to a bigger number to scale the whole thing with the same proportions.

Your heightmap will also affect your terrain size. GDK Advanced Terrains base their size before scaling off the heightmap resolutions. So, without any scaling, supplying a 128x128 heightmap will net you a smaller terrain than supplying a 512x512 heightmap.

Scaling will help, but be prepared to play around with the values to find the right scale for your project, also when you increase the X and Z size of the terrain, you will usually need to increase the Y height aswell, though not by the same degree as the X and Z, to keep the terrain looking the same, otherwise it will seem to "flatten" out as you increase it's X and Z scales.

If it ain't broke.... DONT FIX IT !!!
