The idea of layers to organize and simplify the users experience in editing media is not a new one. Most image editing software like Photoshop or The Gimp have this feature as well as several 3D modeling/mapping programs, including Dark Radiant, of course. If you are new to the concept of layers, just imagine them as a convenient way to hide elements that are currently in the way. Please note that layers are only a tool to organize your map, they have no effect in the game.
The Layer Inspector
To use Dark Radiant's layer feature, open the layer inspector with the default shortcutor via the View->Layers menu entry. If you haven't tinkered with layers yet you should see a list with exactly one entry called Default (unlike in the screenshot to the right). This is the layer that Dark Radiant automatically creates for you when you begin a new map and that every element belongs to unless you reassign it. It is in every map and can not be removed.
In the layer inspector window you can do the following things:
- By clicking on the checkbox to the left of the layer name you can show/hide a layer respectively it's elements
- Clicking the layer name itself will select/deselect all members of that layer.
- The two buttons to the right of the layer name allow you to change it's name and to delete a layer (in that order). If you delete a layer, it's elements will not be removed from the map, but assigned to the Default layer instead.
- Click on New to create a new layer. You'll be prompted to give it a unique and - preferably - meaningful name.
How to Assign Elements to Layers
Select one or more elements and then right click anywhere in the orthogonal view. At the bottom of the context menu you should see the following items:
- Create Layer...: Same as New in the layer inspector.
- Add to Layer...: If you add something to a layer, it will become a member of this layer but also remains in the layers it alrady belongs to.
- Move to Layer...: Same as above, but the element will exclusively be a member of the newly assigned layer.
- Remove from Layer...: Removes an element from a layer. Note that the list shows all layers, not only those that the selected element is a member of.
There are no real alternatives to layers but two very convenient companions that you may use alongside:
