====== Generating a preview of the heightfield ======
L3DT allows you to generate a preview of the heightfield. The preview can be at lower, equal or higher resolution than the full heightmap, and can be of either the whole heightfield or a sub-region thereof.
To generate a preview of a sub-region, first use the [[l3dt:userguide:tools:selarea|select area tool]] on the design map to select the area to be previewed, as shown below. If you are generating a preview of the whole heightfield, please skip this step.

^ Selecting an area of the design map ^
Then, select the '//Operations->Heightfield->Preview area from DM//' menu option. This will open the //Select HF/DM ratio// window, which allows you to generate the heightfield preview at lower resolution (faster), higher resolution (more detailed), or the same resolution as the regular heightfield.

^ Selecting the heightfield resolution. ^
The option selected by default is the current resolution of the heightfield, as was set in the [[l3dt:userguide:wizards:design|design map size]] wizard when the project was created.
* If you select a smaller value, the preview will generate more quickly, but will be less detailed.
* If you select a greater value, the preview will generate more slowly, but will be more detailed.
When you click //OK//, L3DT will proceed to generate the heightfield preview, which will overwrite the heightfield in the project if present.
