====== Feature scale (DM parameter) ======
The 'scale of features' slider in the //[[l3dt:userguide:wizards:designparams|design map parameters]]// wizard determines the height //and// width of features in the design map, such as valleys and hills. With a large feature scale setting, your map will feature taller and wider mountain ranges, whereas with a smaller feature scale setting, you map will consist of smaller hills.
This is demonstrated below, where where I've made terrain with feature scale settings from 0% up to 100%:

| 100% (right, vast) | {{l3dt:algorithms:dm:params:featurescale:featurescale_100_dm.png?200}} | {{l3dt:algorithms:dm:params:featurescale:featurescale_100_hf.png?200}} | {{l3dt:algorithms:dm:params:featurescale:featurescale_100_3d.jpg?300}} |
If you would like to increase or decrease only the height of the terrain, without changing the width of the features, use the [[l3dt:algorithms:dm:params:altrange|altitude range]] setting instead.
