===Terrain and Water Height=== | |||
0x0c through 0x18 are used to determine what height range the terrain and water should render within. This is possibly used to assist with occlusion. If the heightmap moves outside of the range defined here, there will be visual artefacts present at higher viewing angles, usually between 45 and 90 degrees. The range value is multiplied by the max height defined in the TSCB header to determine the final value in 'real' co-ordinates. | |||

After the Header, there are <code>extra_info_array length / 4</code> elements of this structure. | After the Header, there are <code>extra_info_array length / 4</code> elements of this structure. | ||
Elements act as flags for presence of [[Water.extm|.water.extm]] or [[Grass.extm|.grass.extm]] files. | |||
A "water" element indicates that there is water data for the terrain section defined in a [[Water.extm|.water.extm]] file. A "grass" element similarly indicates the presence of a [[Grass.extm|.grass.extm]] file. | |||
Grass and water are referenced via the <code>extra_info_array</code> because presence water and grass data for any given terrain area is optional. | |||
