Some functions take map handles as arguments, including most of the heightfield effect functions. To access a map, we use the GetMap function, like so:
calc.HF.ClampMap <GetMap "HF"> -150.2 1224.6 true
The above code clamps the heightfield (retrieved by <GetMap “HF”>) between an altitude of -150.2 metres and 1224.6 metres, and shows the progress bar whilst doing so (true).
By default, the following map are available:
| Map name | What? |
|---|---|
| “DM” | Design map |
| “HF” | Heightfield |
| “WM” | Water map |
| “WS” | Salinity map |
| “AM” | Attributes map |
| “TN” | Terrain normals |
| “SH” | Shadow map |
| “LM” | Light map |
| “SpecLM” | Specular light map |
| “TX” | Texture map |
