This view actually contains your level! In here, you can arrange and group objects; polyhedrons and entities, and plugin-functions like the duplicator. You can see all entities you've put into your level, and what polyhedrons belong to what entities.

You can right-mouse-click on every tree-view object, to get a context-menu, from where you can select different actions.

Some of the more powerfull functions are:

• Group objects together, and call the group: 'My Front Room', 'Monster Trap', 'Furniture' etc.
• Hide an entire group from the map-views, so it does not clutter your view.
• Change textures on all the selected polyhedrons (or faces).
• Cut, Copy, Paste and Move.
• Change colors on groups, to illustrate different things.

If you wish to enlarge or reduce the Tree-view height, there is a hidden 'drag line' at the very top of the Tree-view, just below the compass. When your curser changes to two bars, with arrows above and below them, you can then hold the left mouse button down and drag the Tree-view to the height you desire.

Most entities (Monster, Weapon, Door) have a set of parameters to set, so they act in a certain way. These parameters are called specifics  in QuArK. Each specific can have an argument (arg) attached to it.

If you do not know what permitted values an arg can have, keep your mouse-cursor steady and a blue 'flyover' help-box will appear, if there is any help to that specific/arg pair.

Sometimes there may be an dropdown-listbox which contain valid args, or most used args. Some specifics are only possible to turn on/off, these looks like checkboxes. There might even be pushbuttons which opens another window, with more specific/arg settings.

The above icons from left to right:

When you have selected a polyhedron, you can see some information and change settings for it, in this view.

Faces  shows how many faces (sides) this polyhedron consists of.

Center  is the X,Y,Z coordinate in the level, where this polyhedron exist. You should not change this manually, unless you don't want to move the poly in the map-views.

Texture  shows the currently applied texture to this polyhedron, as well as a list of used textures in the level, so you quickly (?) can change to another, without opening the texture-browser.

Owned by  displays the name of the group or entity, in which this polyhedron exist.

The icons above the texture from left to right:

Texture	This icon will open the Texture browser so you can select a different texture for the selected polyhedron.
Negative	When this icon are pressed, the selected polyhedron will become a negative poly; it will dig holes into other polys, without actually doing a brush-subtraction.
Face-flags	Some FPS-games have special face-flags to control different behaviour, like transparensy, water, warping, etc. When you click this icon, a new window will appear, in where you can set the flags for all faces of the selected polyhedron.

Used by , is either "parent only" to show that the face is a normal face of its "parent" polyhedron in the tree view, or it is "xx polyhedron(s)" to show that the face is shared (moved outside a polyhedron). It counts how many polyhedrons use this face.

Texture  shows the currently applied texture to this face, as well as a list of used textures in the level, so you quickly (?) can change to another, without opening the texture-browser.

Tex. origin  is both the X,Y,Z coordinate of the face in the level, and texture-position on the face. You should not change this manually, because you might change the size of your polyhedron. Use the intersection-point of the two blue lines instead.

Tex. scale  shows the X,Y scale of the texture on the face. You can also change the scale by dragging in the two blue lines. Some times you might want to mirror a texture, due to some text in it. You should then type in a negative X-scale, or just put a minus sign in front of the current scale-value.

Tex. angles  is the angles of the texture on the face. You should only use the blue dot and lines to change this value.

The icons above the texture from left to right:

In the texture-view below the icons, there is a little blue dot and two blue lines. The blue dot are used to rotate the texture on the face. The lines are used to drag the scale of the texture in X and Y directions. The lines can even rotate independently so the texture gets distorted. The intersection-point of the two lines are used to position the texture on the face.

A quick way to see the selected objects in 3D with textures and their texture-alignments.
