 +You can now use the mouse ((Assuming the default settings)) over the mesh and the front most polygon will highlight underneath the mouse. To help, a crosshair will be drawn on the active viewport as well ((Since LightWave 3D automatically hides the mouse cursor while dragging)).
  
-Polygon Picker tries to limit the meshes to test against, using bounding boxes, to keep the tools as quick as possble.+Once you release the mouse button, a pop-up will be displayed that allows for various actions to be performed on the selection. It will also show some information about the front most polygon.

 ==== Left Mouse Button ==== ==== Left Mouse Button ====
 +
 +The tool differentiates between using the left or the right mouse button to select polygon. Using the right mouse button will *always* open the menu featuring all options.
 +
 +The action for the left mouse button can be configured using this setting.
 +
 +  * **Open Menu** Opens the complete menu, just like the right mouse button does.
 +  * **Open Surface Editor** Only display the options to open the Surface Editor using the current selection. If only one surface is selected, the Surface Editor is opened directly.
 +  * **Open Node Graph** Only display the options to open the Node Editor using the current selection. If only one surface is selected, the NodeEditor is opened directly.
 +  * **Open Selection Menu** Only display the item selection options.
 ==== First Polygon Only ==== ==== First Polygon Only ====
 +
 +If this is enabled, only the first polygon that's intersected is displayed in the menu.
 +
 +Combined with the **Open Surface Editor** or **Open Node Graph** option for the left mouse buttons, this allows for performing either of these actions directly, without a pop-up menu opening.
 ==== Deep Mesh Inspection ==== ==== Deep Mesh Inspection ====
  
 This open is only available if **First Polygon Only** is disabled. This open is only available if **First Polygon Only** is disabled.

 +Polygon Picker traces a ray into the scene using the current mouse location. By default, only the first hit polygon per item/mesh is collected.
 +Enabling this option will probe for further polygons within that item/mesh, behind the initial first polygon. 
 ==== Preselection Highlight ==== ==== Preselection Highlight ====
  
 +If this option is enabled, the Polygon Picker will perform as follows:
 +   - The mouse button is pressed in a view.
 +   - As the mouse is dragged over the view, the current front most polygon is highlighted in all views. A crosshair is drawn on the active view.
 +   - Once the mouse button is released, a menu is displayed to perform an action (or the action is performed directly, depending on the settings).
  
 +If it is disabled, the Polygon Picker will perform in a simpler manner:
 +   - When a mouse button is pressed over a view, the scene is probed at that position and a menu is displayed to perform an action (or the action is performed directly, depending on the settings).
