This mode is used to create detail mesh entities. These are useful for adding details to a level without much impact on the performance.

• Main category: this ComboBox is used to select the current set of objects. Sets should map to directories under the static_objects directory in redist.

• Subcategory: this ComboBox will show all subsets inside the set picked previously.

• Object list: all objects under the selected subcategory. Clicking on an entry will select a static object file to be used in following placements.

• Thumbnail: shows a little picture so you can see how the object looks like.
• Create on surface: when this is on, you are able to create objects on the surface of other objects, such as static objects, entities, primitives or terrain.

• Scale settings: this sets the scale for the object on creation. Can be set to a fixed or a random value, the latter defined by a range given by both scale inputs, min and max.

• Rotation settings: this sets the rotation for the object on creation. Can be set to a fixed or a random value, the latter defined by a range given by both rotate inputs, min and max.

• Color settings: this will define a color range from which a color will be picked for every new placed object.
