(default keyboard shortcut D)
Modeler’s interface is highly configurable allowing to tailor it to your specific needs. You can change the arrangement of viewports as well as change the display characteristics for each viewport independently. Choose Edit > Display Options to bring up the Display Options Panel.
Layout Tab
Layout options control the global arrangement of the viewports, the number of viewports and some other Global Display settings. Use the Presets pop-up menu to quickly set common layout configurations (Quad is the default setting). Selecting a Preset will affect the Layout setting, as well as settings on the Viewports Tab.
If you want to set up your own custom layout, make a selection from the Layout pop-up menu. The icon to the left of the description will give you an idea of how the viewports will be arranged. Later, you will see that you have total control over what is in each viewport. In fact, each Layout option will remember the Viewport settings as they were the last time that Layout option was used.
Perspective Amount - The amount of perspective in the perspective view can be varied by changing the Perspective Amount slider on the Layout Tab. You can go from a very wide-angle to a flat nearly orthogonal view. The setting is global and affects all the perspective views the same way.
Background Color - Use the Background Color selector to change the color that appears in the background for viewports using a shaded display.
Default Sketch Color - Use the Default Sketch Color setting to change the color that the wireframe will appear in the various view modes. You can always change the Wireframe color on polygons using the Sketch Color tool located under the Detail Tab.
Selection Color Options - Use the Selection Color Palette for editing Point > Edge > Polygons when selected. Other options include changing the color for Normals and the color of active Tools.
Tool Color - Specifies the color for tool gizmos and Syncmesh tool text.
HUD Color - Specifies the color for the viewport surround when editing morphs.
HUD Opacity - Defines the strength of the color used for the HUD.
Fixed Normal Length - Change the length of the normal here.
Show Options The various Show Visibility options let you independently set what you want to see globally in your viewports.
Show Points - Points appear as small dots
Show Points OnShow Points Off
Show Surfaces - Surfaces are the polygon (or SubPatch) surfaces
Show Surfaces OnShow Surfaces Off
Show Cages - A cage is the outline that connects all of the control points when you edit a SubPatch object
Show Cages OnShow Cages Off
Show Point Selection - When points are selected they appear highlighted if this option is selected
Show Guides - Guides are the dotted-lines that extend from the surface (patch vertex) to the control points on the cage (if visible) when you edit a SubPatch object
Guides onGuides off
Show Normals - Normals are dotted lines that extend perpendicularly from selected (planar) polygons and indicate the direction a polygon is facing
Show Origin - This option will show the 0 axis in the viewports. For the perspective view, only the X and Z axis are shown.
Show Grid - The grid is the background reference grid
Show Polygon Selection - When polygons are selected they appear highlighted if this option is selected
Show Backdrop - A Backdrop is an image loaded for viewports on the Backdrop Tab. These images can be useful as Modeling reference
tip
These visibility options can be overridden independently for each viewport on the Viewports Tab.
Show Edge Selection - When edges are selected they appear highlighted if this option is selected.
GL Tab
Texture Resolution determines the display resolution of images used. Lower settings will update faster and use fewer system resources.
Texture Resolution - The Texture Resolution setting determines the resolution to use for displaying textures in viewports that have their Rendering Style set to Texture. Higher settings increase the detail of image textures displayed in viewports, but increase memory usage and display refreshing time.
Shading Method - Choose between MultiTexture shaders and GLSLShaders. Multi-texture shaders are simpler and intended for graphics cards that are less capable. GLSL is faster and shows more texture capabilities for modern cards.
Transparency Sorting - There are three options to choose from:
SortByObject - sorting the objects by their distance from the camera - fast method
SortByPolygon - sorting polygons by their distance from the camera - slowest method
AlphaClipping - uses the alpha value of a texture in the transparency channel to determine transparency - fastest method
SortByObject is the default setting and will be the fastest in most cases.
Geometry Acceleration - Determines how the graphics card displays OpenGL. Streaming renders the mesh immediately to screen, using the lowest amount of memory at the cost of speed. Buffered(VBO) will attempt to store the geometry in graphics card memory, allowing for the highest speed, at the cost of memory. In cases where the mesh or shading changes with every frame no caching is possible, a fallback to the Streaming method will result, for example with animated meshes and reflection maps. Smooth shaded geometry will benefit the most from the Buffered(VBO) mode. If the mesh is buffered in graphics card memory the performance you will get as much performance as your graphics card can give you.
Pixel Blending - means texture filtering (mip-mapping)
Mipmapping - Mipmapping is similar to what is used in today’s games to avoid graininess of textures in a distance or at a flat angle. Basically lower- res versions of the texture are generated in realtime and blended in. This feature is supported in hardware by most of today’s graphics cards. Please note however that due to the nature of this filtering method, low-resolution textures may appear a bit blurry.
Reflections - Turns on reflection shading for Modeler
Viewport options let you change how objects are displayed in each viewport. To change the settings for a viewport, first select it using the Viewport buttons.
Use the Presets pop-up menu to quickly set the options on this tab for the selected viewport region. The selections are listed by view types, but will affect all of the settings on this tab.
The View Type pop-up menu determines the editing axes you want to use for the selected region.
For the Orthogonal settings, the names generally indicate the viewing perspective. Back (XY), for example, lets you edit along the X and Y axes. This means you are looking along the Z axis.
Since it is called Back, that means your perspective is from the back (i.e., negative side) of the Z axis, looking toward the positive side. UV Texture is entirely different - it is not used as a Modeling viewport but for adjusting UV texture maps.
tip
There are four Display (group) commands assigned by default to certain keyboard shortcuts which affect the viewport beneath your mouse pointer. Shift F1 toggles the view between Back and Front, Shift
F2 toggles between Top and Bottom, Shift F3 toggles between Right and Left, and Shift F4 toggles between Perspective and UV.
Perspective You may edit in a Perspective viewport, just as you would in any other, but you may also rotate your view perspective. This is Modeler’s virtual trackball, which enables you to rotate the object without affecting its orientation in the other three edit windows. It effectively provides you with three axes of rotation. While holding down the Alt key, you can perform these actions:
Rotate around the X axis (pitch) by dragging up or down directly across the verticle center of the viewport
Rotate around the Y axis (heading) by dragging left or right directly across the horizontal center of the viewport.
Rotate around the Z axis (bank) by dragging to the left or right around the perimeter If the title bars are visible, you can drag the rotate drag button with your LMB to rotate. If you use the RMB, the viewport will rotate around its perpendicular axis. Holding the
Ctrl key (or using your MMB) will cause rotations to snap to 15-degree increments.
tip
Imagine you are manipulating an imaginary ball with your mouse when you manipulate the Preview window.
Rendering Style - The Rendering Style pop-up menu determines the style of display you want to use for the selected region:
Wireframe - Although the Wireframe is arguably the most limited display mode, it is the most commonly used Rendering Style because of its ease in viewing, selecting, and unselecting points and polygons.
Color Wireframe - This is nearly the same as Wireframe, except the polygon edges are drawn using their Sketch color (Detail > Polygons > Sketch Color).
Hidden Line - Hidden Line shows an object’s Front Face polygons in wireframe view.
Sketch - Sketch shows an object in a combined wireframe and flat-shaded view. All polygon edges are drawn, but faces are also visible. This mode does not account for Surface settings, however. The polygon edges are always drawn in white and faces are grey. Background layers are visible.
You can change the polygon shading color in this mode by choosing Detail > Polygons > Sketch Color.
Wireframe Shade - Wireframe Shade is a smooth-shaded mode that overlays the wireframe lines.
Flat Shade - In Flat Shade mode, the object is shown as a flat-shaded solid. This mode supports some Surface settings, but not smoothing.
Smooth Shade - Smooth Shade is a smooth-shaded mode that supports some Surface settings, such as Color, Diffusion, Specularity, Glossiness, Smoothing, and Double-sided.
Texture - Texture is similar to Smooth Shade, but it also shows images mapped to surfaces.
Textured Wire - Textured Wire is similar to Texture, but it also shows wireframes on the surfaces.
Upright Rotation - The Upright Rotation pop-up menu lets you rotate a viewport clockwise by 0, 90, 180, and 270 degrees to accommodate imported objects from applications that may use other axes as up, or for exporting to them, for that matter.
Titlebar Shortcuts You can change the View Type and Rendering Style of a viewport without going to the Display Options Panel by using the pop-up menus on the title bar. Clicking on the left-most pop-up allows you to choose which View Type you want to be in and will then display it. The pop-up menu just to its right lets you choose the Rendering Style.
Note that if you have UV Texture selected as the View Type, the Rendering Style pop-up menu will instead list all loaded images. Select one to load it into the backdrop of that viewport.
Independent Options The Independent options let you make certain viewport characteristics independent from other viewports. Changes to the selected characteristic do not affect it in other viewports and vice versa. For example, if a viewport uses Independent Zoom, zooming in it does not affect the zoom of other viewports. You must have your pointer over the viewport to affect an independent viewport. Independent Rotation is only applicable to perspective views. Normally, it is enabled. If you have multiple perspective views and this option disabled, they will move in unison when you rotate a view.
Independent Visibility The lower portion of the panel contains the independent visibility options. You can individually select which visibility options are independent. To use them, you must also activate the Independent Visibility option. This option lets you quickly enable/disable this feature without losing the state of each setting.
Backdrop Tab
On the Backdrop Tab, you can add full-color backdrop images that act as reference guides when you build objects. They let you model much like tracing a picture using tracing paper. To use backdrops, select the Viewport and the desired image from the Image pop-up menu.
note
Where possible, use square images.
tip
If you are using a UV Texture viewport, you can choose a backdrop using any loaded image from what is normally the Rendering Style pop-up menu on the viewport’s title bar.
From the Presets pop-up menu, you can save the settings for the selected Viewport to a file by choosing Save Current Backdrop. You can load this file later using Load Backdrop for any selected Viewport. You can also save the settings for all viewports by choosing Save All Backdrops. When this file is loaded later - using Load Backdrop - the individual Viewport settings are restored.
tip
The backdrop images for the current default layout for each view configuration are cached as long as possible. Also, backdrops are not saved in config files or view presets.
Use the Image drop down menu to select from the loaded images or choose (Load Image) to bypass the Image Editor and load a new image into Modeler and automatically select it for the current viewport.
You can also adjust Brightness and Contrast. Use the sliders to adjust the settings. You can invert the colors by activating the Invert option. If you want to blend pixels for close-up work, activate the Pixel Blend option. Image Resolution determines the accuracy of the displayed image.
tip
Colored background images sometimes make the wireframe hard to see (especially if the image has a bright white background). Setting the Contrast to its lowest value, and the Brightness to a little above the darkest value will produce a reasonable-looking backdrop that works well when Modeling.
Aspect and Video images The two Center and Size input fields are horizontal (top field) and vertical (lower field). Clicking Automatic Size will enter values that fit the defined image into an implied bounding box that surrounds visible geometry.
If you activate the Fixed Aspect Ratio option, you can enter a frame aspect ratio in the input field. Then, you only need to specify a horizontal size - the vertical size is computed automatically. If your images originated from video, you need to account for the pixel aspect ratio, since video pixels are not square like computer pixels. For example, a D1 NTSC image is 720 x 486 pixels; however, the frame aspect ratio is not 1.48 (720/486) as you might expect. The width of a D1 NTSC pixel is 90 percent of the width, that is, a pixel aspect ratio of .9. As such, the true frame aspect ratio is 1.333 (720/486*.9).
tip
The frame aspect ratio of a D1 PAL image is also 1.333 (720/576*1.067).
If you do not account for this difference, your models may appear slightly stretched when ultimately viewed on video. A way to fix this is to scale the object after the fact.
Interface Tab
The Alert Level affects how error, warning and informational messages are displayed. The Toolbar Position setting determines if the main toolbar appears on the Left or Right side. Activate Hide Toolbar to make it hidden and maximize your screen real estate. Alt +F2 will hide (and more importantly, Unhide) the Toolbar as well.
Toolbar On/Toolbar Off
The Viewport Titles option turns the titlebars, which appear above each viewport, on or off.
Toolbar On, Viewport Titles Off
Use the Input Device buttons to select the type of input device you are using.
You can optionally set Mouse Wheel Zoom to enable the use of the mouse scroll wheel to zoom in and out of a viewport. As with using the Ctrl Alt shortcut, the view will zoom based on your mouse pointer’s location.
The next option is for Double-click Deselect. This gives you the possibility to double-click on any empty space in the Modeler interface to deselect all selected Points, Edges or Polygons. You will still be able to use a single click in the normal deselect areas (under the menu buttons, on top of viewports, etc.) will this option is engaged.
The Fine Detail Cursor option, when active, makes your mouse pointer use the main crosshair pointer (Point mode) at all times instead of changing when the various tools and selection functions are used.
Fine Detail Cursor
The File Dialog pop-up menu lets you use custom LightWave dialogs for file loading/saving. Selecting Default will use your standard system dialog.
The custom File dialog provides many additional features not available with the standard system dialogs.
The Visual Browser - You can make the LightWave visual browser the default file dialog for Layout and/or Modeler by choosing VBFileRequester on the File Dialog pop-up menu. This appears on the Interface Tab of Modeler’s Display Options Panel (Edit > Display Options).
The Color Picker pop-up menu lets you use custom LightWave dialogs for picking colors. By default it is set to the LightWave color picker shown below, but if you wish you can choose the system color picker here.
The Color Format setting determines the scale used where the color selector appears. Integer uses values 000 to 255, Float uses .00 to 1.00 and Percentage uses 0% to 100%.
The Simple Wireframe Edges option turns off polygon offsetting for the sketch-like display modes. This may fix display problems on some video cards. The Simple Wireframe Points setting uses OpenGL’s own points for wireframe points and selected points at a user-specified size. These points can draw much faster than the standard points.
Units Tab
The Unit System determines the units of measurement that are used and displayed by the Modeler screen.
SI - is the International System of Units (SI is the abbreviation of the French “Le Système International d’Unités”). Unit measurements in Modeler will use a base system of meters. Grid sizes and distances can be measured in megameters, kilometers, meters, millimeters, micrometers, and nanometers.
Metric - The Metric System is the same as SI with the addition of centimeters.
English - The English System uses miles, feet, and inches.
tip
We recommend you use the SI or Metric systems to model objects, since a system using base 10 is often much easier to use for purposes such as applying textures and adjusting object movement.
If you input a value that uses a different unit of measurement than that of the default, LightWave will convert it on the fly. For example, you may be using meters, but typing in “5 ft” will convert to “1.524 m.”
Default Unit - Use the Default Unit pop-up menu to set an assumed measure when none is given for distance values.
tip
If you use a metric Unit System, you should set the Default Unit to meters.
Grid Units affects the zoom step amount but has no effect on the actual size of the object. You will likely find that 1 2.5 5 and 1 2 5 are your most commonly used Grid Unit settings.
1 - The grid resizes in values that begin with 1, as in 10m, 1m, 100mm, 10mm, etc.
1 5 - The grid resizes in values that begin with 1 or 5, as in 1m, 500mm, 100mm, 50mm, 10mm, etc.
1 2.5 5 - The grid resizes in values that begin with 1, 25, or 5, as in 1m, 500mm, 250mm, 100mm, 50mm, etc.
1 2 5 - The grid resizes in values that begin with 1, 2, or 5, as in 1m, 500mm, 200mm, 100mm, 50mm, etc.
1 2 - The grid resizes in values that begin with 1 or 2, as in 1m, 200mm, 100mm, 20mm, 10mm, etc.
Grid Snap - The Grid Snap setting forces point creation and item movement to be limited to a specific increment.
None - None deactivates grid snap, so that items move freely and are not constrained by any grid intersections.
Standard - Standard sets the grid snap to one-tenth of the current grid size.
Fine - Fine makes the grid snap as small as possible for the current zoom level. This will be typically two to five times smaller than using Standard.
Fixed - Fixed lets you specify the increment of movement in the Snap Value input field. The grid will resize itself to use the value you specify.
Time Format - The Time Format setting allows you to set the display format for time values, like the Frame Slider Label option on Layout’s General Options Tab of the Preferences Panel. If the Hub is active, Layout and Modeler settings will be kept in sync.
