Polygon Picker

Polygon picker allows you to pick a polygon in any of the views that display meshes in Layout (regardless of the view mode) and then perform actions based on that selection, such as opening the Surface Editor or the Node Graph editor for the surface used by that polygon.

Advanced options allow you to customise is just the first polygon is selected, or all polygons underneath the mouse cursor.

Additionally, items underneath the mouse cursor may be added to or removed from the current item selection in Layout.

To use the tool, assign it to a menu or a shortcut. Activate it and click inside a viewport. Depending on the meshes underneath the cursor, there may be a longer delay as LightWave 3D computes the acceleration structures for the picking 1). You can now use the mouse 2) 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 3).

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.

Polygon Picker tries to limit the meshes to test against, using bounding boxes, to keep the tool as snappy as possble.

As with all tools, it has to be dropped once you're done with it (the easiest way is to press the space bar).

Settings

Polygon Picker is highly configurable to align with different use cases.

The panel exposing the settings can be opened using the n key any time the tool is active. The settings are stored in the LightWave 3D config directory for the LightWave 3D version you're running.

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

Deep Mesh Inspection

This open is only available if First Polygon Only is disabled.

Preselection Highlight

1)
This is only done once per mesh in the scene and will be re-used in subsequent uses of the tool.
2)
Assuming the default settings
3)
Since LightWave 3D automatically hides the mouse cursor while dragging
