TrenchBroom Help - Keeping an Overview

## Keeping an Overview

Sometimes, the 3D view can get cluttered in maps with a lot of detail or many entities. That's why there are several options to reduce the amount of objects in the 3D view. You can select between textured, flat and wirefame rendering, you can filter the 3D view so that only certain objects are rendered and you can isolate, hide or freeze the current selection.

### Information Bar

The information bar at the top of the 3D provides you with information about the current selected, such as:

- Two brushes are selected which belong to two different entities. Both entities have three brushes in total.
- One point entity is selected, its classname is info_player_coop.
- One of two world brushes is selected, the vertex tool is activated and two of the selected brush's eight vertices are selected.

Note that the information bar displays its information in the form of a path. You can navigate up this path by selecting
from the menu. In the last example above, selecting this command repeatedly will first deselect all vertices, then deactivate the vertex tool, then deselect all selected brushes.

In the right of the information bar there is a search field. Trenchbroom will display only those objects whose key names or key values match the entered text. For example, say you had two monster_shambler entities. One of them had a 'targetname' key with the value 'scary' and the other had 'target' set to 'scary'.

- If the filter was set to "shambler", both monsters would be visible
- If the filter was set to "scary", both monsters would be visible
- If the filter was set to "targetname", only the first monster would be visible
- If the filter was set to "target", both monsters would be visible (because 'targetname' is a partial match)

### Render Modes

Render modes (click to cycle through the modes)

You can choose from three render modes in TrenchBroom in the View tab of the inspector. The following modes are available:

- Textured - All faces are rendered with their textures.
- Flat - All faces are rendered with the average color of the texture.
- Wireframe - Faces are not rendered at all.

### Selection Hiding

Sometimes it can be beneficial to hide objects that may be cluttering up the view. This can done with the Hide Selection command (
). To unhide objects, use the Unhide All command (
).

### Selection Isolation

Very often, you'll want to isolate the selected objects to edit them with more ease in the 3D view. TrenchBroom provides this ability through the Hide Unselected command (
). To unhide objects, use the Unhide All command (
).

### Locking the Selection

TrenchBroom provides the ability to lock the current selection in place, freezing it and making it safe from unintended edits. This is done with the Lock Selected command (
). To unlock objects, use the Unlock All command (
).

### Locking Unselected Objects

You can also lock unselected objects, allowing you to edit the selection while being unable to edit anything else. This is done with the Lock Unselected command (
). To unlock objects, use the Unlock All command (
).

### Render Filters

Render Filters

You can select the types of objects which should be rendered in the 3D view by using the render filters in the View tab of the inspector. There are two categories with different checkboxes for each in the Filter section:

- Entities - Render entities in the 3D view.

- Models - Render entity models in the 3D view.
- Bounds - Render entity bounding boxes in the 3D view.
- Classnames - Render entity classname labels in the 3D view.

- Brushes - Render brushes in the 3D view.

- Clip brushes - Render brushes entirely textured with the 'clip' texture.
- Skip brushes - Render brushes entirely textured with the 'skip' texture.
- Hint brushes - Render brushes entirely textured with the 'hint' texture.
- Liquid brushes - Render brushes entirely textured with a liquid texture.
- Trigger brushes - Render brushes entirely textured with the 'trigger' texture.

Unchecking a checkbox will remove the appropriate type of object from the 3D view.
