Layout Commands

Layout commands are case-sensitive. Layout's native command mechanism is the evaluate function, with the command name and its arguments passed as a single, space-delimited string. Commands issued using the lookup and execute functions will be translated into evaluate strings before being processed, and the command arguments passed to execute must all be DynaValues of type DY_STRING.

Layout doesn't strip quote marks from arguments. They're treated literally, so they should only be included when they're actually part of the argument. (There aren't any commands whose argument lists require anything other than spaces to delimit the arguments.)

Most Layout command arguments are optional. If the argument isn't supplied, Layout will prompt the user for the argument. In the command list that follows, the data types of the arguments are denoted by the initial letter. (The same letters are used in C printf formatting.)

number
An integer.
gfloat
A floating-point number.
string
A string, such as a filename or channel name.
hex
A hexadecimal number, such as an item identifier.

The commands are divided into 15 categories, roughly according to what they do and which globals provide the current values of the parameters they set.

Selection

Most item-specific commands operate on the currently selected item. The Interface Info global returns a list of the currently selected items.

SelectItem xID
SelectByName sname
AddToSelection xID
RemoveFromSelection xID
Select an item by item ID or by name, or add and remove an item from the list of selected items.

AddCamera sname
Add a camera to the scene.
ClearAllCameras
Remove all cameras from the scene and restore the default camera.
FrameSize nwidth nheight
ResolutionMultiplier gmultiplier
Set the size of the output image. The resolution multiplier makes it easier to scale the image up or down without affecting (or knowing) the base frame size.

Items

These commands operate on the currently selected item and work with items of all types. Use the Item Info or Interface Info globals to get the current values of the parameters set by many of these commands.

ClearSelected
Remove the selected items from the scene.
Rename sname
Rename the item. This works for all item types except objects, which derive their names from their filenames.
Clone nclones
Create one or more clones of the item.
ItemActive nactive
Make the item active or inactive. An inactive item doesn't participate in rendering calculations. Inactive objects are 100% dissolved, and inactive lights have an intensity of 0. For bones, the command is a synonym for the BoneActive command. It currently has no effect on cameras.
ApplyServer sclass sserver
Apply a plug-in. The arguments are the first and second fields of the ServerRecord for the plug-in.
RemoveServer sclass nindex
Remove a plug-in. The index refers to the list of applied servers of a given class. The first server in each list has an index of 1.
AddEnvelope schannel
RemoveEnvelope schannel
Create or remove the envelope associated with a parameter in Layout. These commands "press the E button" for envelopes Layout itself maintains. Use them for envelopes not created by your plug-in through either the Variant Parameters or Animation Envelopes globals. The channel argument is the same as the channel name displayed in the Scene Editor when an item's channel list is expanded.
SchematicPosition nX nY
Set the position of the current item within schematic views. The coordinates are relative to the upper left corner of the view pane.
ItemLock nlocked
Lock or unlock the selected item. A locked item can't be selected by clicking on it in the view.
ItemVisibility nvisibility
Set the visibility of the selected item. The argument can be any of the values returned by the Interface Info global's itemVis function.
ItemColor ncolor
Set the wireframe color of the selected item. The argument is an index into a color table.

Motion

Motion commands operate on the current item. Use the param function of the Item Info global, as well as the Animation Envelopes and Channel Info globals, to read motion-related settings.

CreateKey gtime
Create a key for all nine motion channels (position, rotation and scale). If a key already exists, this changes its settings.
DeleteKey gtime
Delete all of an item's motion keys at a given time.
AutoKey
Toggle the Auto Key setting. When on, changes in the position, rotation or scale of an item are automatically recorded to a key. When off, a key must be created explicitly.
Position gX gY gZ
Rotation gH gP gB
Scale gX gY gZ
Position, rotate or scale the item. This has no effect on keys at the current time unless Auto Key has been turned on.
AddPosition gX gY gZ
AddRotation gH gP gB
AddScale gX gY gZ
Increment the motion. Like Position, Rotation and Scale, but the values are relative rather than absolute.
PivotPosition gX gY gZ
PivotRotation gH gP gB
Set the position and rotation of the pivot (the origin of the item's rotation).
RecordPivotRotation
Add the current item rotation angles to the pivot rotation, and reset the item rotation angles to (0, 0, 0).
Numeric
Prepare for numeric entry. The specific behavior depends on which tool is active. For the Move, Rotate and Size tools, this activates the vector edit fields, and values typed after this will be entered there.
EnableXH
EnableYP
EnableZB
Unlock or lock a channel against changes caused by mouse dragging. Which channel is affected depends on which tool is active. If the Move tool is active, for example, EnableXH toggles the enable state of the X channel, and when it's disabled, moving an item by dragging the mouse may affect the Y and Z components of its position, but not the X component.
WorldCoordinateSystem
ParentCoordinateSystem
LocalCoordinateSystem
These affect the coordinate system in which mouse movement is interpreted for the motion tools. Moving the mouse can move an item along the world, parent or local (item) axes.
LoadMotion sfilename
SaveMotion sfilename
Load or save an item's keyframes in a motion file. The format of the file is similar to the format of the key data in scene files.
Undo
Undo the most recent motion change.
Reset
Set an item's animation channels to the values they had when the object was created or loaded. Which channels are affected depends on which tool is currently active. Channels disabled by EnableXH, EnableYP or EnableZB are not reset.
ParentItem xID
Set the parent of the current item to the item given by the ID. The item's motion is relative to that of its parent.
ParentInPlace
A global setting. When turned off, setting a parent relationship causes the child item to jump to a new (world coordinate) position, since the child's position setting suddenly becomes relative to that of its parent. When turned on, parenting in place prevents the jump, adjusting the child's position relative to its parent so that its world position doesn't change. This setting can be read as a flag using the Interface Info global.
TargetItem xID
Set the target of the current item to the item given by the ID. The item will rotate so that it points toward the target.
PathAlignLookAhead gtime
Set the look-ahead interval, in seconds, for motion channels controlled by Align to Path. This is the amount of time by which changes in orientation of the item anticipate changes in the path direction.
EnableIK
A global toggle that enables or disables inverse kinematics calculations for all items.
UnaffectedByIK
Toggle the Unaffected by IK of Descendents option. When on, the item is isolated from the motion effects of inverse kinematics applied to the item's children. The item becomes the base of the IK chain containing its children.
GoalItem xID
Set the IK goal of the current item to the item given by the ID.
FullTimeIK
Toggle Full-time IK for the item. This determines whether IK is recalculated each time the item's goal is moved.
GoalStrength gstrength
Set the strength, or amount of influence, of an item's IK goal. The goal strength is relative to that of the other goals associated with an IK chain.
MatchGoalOrientation
When on, this toggle causes the item's rotation and scale to match that of its goal.
KeepGoalWithinReach
When on, this toggle constrains the motion of the goal so that it's always "attached" to the item.
HController ncontroller
PController ncontroller
BController ncontroller
Set the controller for each rotation channel. The argument can be any of the values returned by the Item Info controller function.
HLimits gmin gmax
PLimits gmin gmax
BLimits gmin gmax
Set minimum and maximum limits for each rotation channel.
RecordMinAngles
RecordMaxAngles
Use the current rotation of the item as the minimum or maximum limit for all three rotation channels.
LimitH
LimitP
LimitB
Enable or disable rotation limits.
HStiffness gstiffness
PStiffness gstiffness
BStiffness gstiffness
Set the stiffness (resistance to rotation via IK).

Effects

These commands affect settings on the Effects panel. Use the Backdrop Info and Fog Info globals to read these settings.

GradientBackdrop
ZenithColor gred ggreen gblue
SkyColor gred ggreen gblue
GroundColor gred ggreen gblue
NadirColor gred ggreen gblue
Enable or disable the gradient backdrop, and set its key colors.
FogType ntype

Set the distance extents of the fog.
FogMinAmount gamount
FogMaxAmount gamount
Set the fog amounts at the minimum and maximum distances.
FogColor gred ggreen gblue
Set the fog color.

Scenes

These commands involve render options and scene loading and saving. You can read many of the parameters using the Scene Info global.

ClearScene
Clear the scene. All items are removed and all scene parameters are reset to their default values.
LoadScene sfilename
Load a scene file.
LoadFromScene sfilename
Load the objects, and optionally the lights, from a scene file.
SaveScene
SaveSceneAs sfilename
Save the scene.
SaveLWSC1 sfilename
Save the scene in version 1 format. This is the scene file format used by versions of LightWave prior to 6.0. Some information may be lost, since the old format doesn't support many of the newer features.
SaveSceneCopy sfilename
Save a copy of the scene. Unlike SaveSceneAs, SaveSceneCopy doesn't rename the scene.
ContentDirectory sdirname
Set the content directory (a file system path). Objects and other files referenced in the scene are listed relative to this path.
FirstFrame nframe
LastFrame nframe
FrameStep nframes
Set the frame range and step size for rendering.
FramesPerSecond gfps
Set the playback speed of the animation. This is used to convert between frame numbers and elapsed time in seconds.
AutoFrameAdvance
Toggle the Auto Frame Advance feature. During rendering with this turned off, the user must confirm before each frame is rendered.
EnableVIPER
Enable or disable the VIPER (Virtual Interactive Preview Render) system. Enabling VIPER allows it to store buffers from the most recently rendered frame, but doesn't open the VIPER window.
RayTraceShadows
RayTraceReflection
RayTraceRefraction
RayTraceTransparency
Toggle raytracing of shadows, reflection, refraction and transparency.
RenderFrame
RenderSelected
RenderScene
Render the current frame, render only the currently selected objects in the frame, or render all frames.

These commands are concerned with the user's navigation within Layout's interface, but being able to set the current frame and animate the display is also useful to plug-ins. The current frame is available from the Interface Info global as the current time. Use the framesPerSecond field from the Scene Info global to convert this to a frame number.

Some of these commands operate on a single view pane, the one that currently contains the mouse cursor.

GoToFrame nframe
PreviousFrame
NextFrame
PreviousKey
NextKey
Shuttle the display to a specific frame, an adjacent frame, or the next or previous frame containing a motion key.
Refresh
RefreshNow
Tell Layout to recompute motions and geometry. After changing the current frame, plug-ins that bake geometry can issue the RefreshNow command so that vertex positions are updated immediately. By default, Refresh runs during idle time, which won't occur while a plug-in's code is executing.
Redraw
RedrawNow
Redraw the display. Like RefreshNow, RedrawNow executes immediately rather than waiting for idle time. But the draw commands by themselves don't cause motions and geometry to be recomputed.
PlayForward
PlayBackward
Pause
Animate the display, or make it stop animating.
PreviewFirstFrame nframe
PreviewLastFrame nframe
PreviewFrameStep nframes
Set the range of frames and the frame step for animating the display. The frame range also affects the range of frames that are accessible to the user through the frame shuttle control.
MakePreview
PlayPreview
FreePreview
LoadPreview
SavePreview
Manage pre-rendered previews. These store the animated display as an image sequence.
ClearAudio
LoadAudio
PlayAudio
Manage Layout's audio track.
FractionalFrames
When this toggle is set, Layout allows the user to move the frame shuttle to non-integer frame numbers.
CenterMouse
Center a view over the current mouse position.
CenterItem
Center a view over the position of the selected item. This is a toggle that causes the view to remain centered on the item while it's being moved.
FitAll
FitSelected
Scale and move a view so that it contains all items or all selected items.
ZoomIn
ZoomOut
ZoomInX2
ZoomOutX2
Scale a view. The X2 versions scale the view by a factor twice as large.

Display

These commands set display options. Many of these can be read from the Interface Info global. As with some navigation commands, many of these commands operate on the view pane that contains the mouse cursor.

GridSize gsize
IncreaseGrid
DecreaseGrid
Set the grid size, or scale it in approximately logarithmic steps: 1, 2, 5, 10, 20, 50, and so on. The grid size is the interval in meters between grid lines in the display. The scale of the view is relative to this size, so the entire scene (but not the grid) will appear to grow or shrink in the view panes as this number is changed.
DynamicUpdate nlevel
Set the amount of display interactivity. The level can be any of the values that are valid for the Interface Info dynaUpdate field.
ShowMotionPaths
ShowHandles
ShowIKChains
ShowCages
ShowSafeAreas
ShowFieldChart
ShowTargetLines
Toggle the drawing of these display components.
BoundingBoxThreshold nthreshold
Set the minimum number of points at which an object will be drawn initially as a bounding box. Lower numbers improve interactivity, but plug-ins that bake geometry transformations may need to set this above the number of points in the object they're baking. Otherwise only the bounding box vertex positions will be computed by Layout.
TopView
BottomView
BackView
FrontView
RightView
LeftView
XYView
XZView
ZYView
PerspectiveView
LightView
CameraView
SchematicView
Set the type of view in a view pane. The first six are orthographic views in the direction of the world -Y, +Y, -Z, +Z, -X and +X axes, respectively. XYView (X increasing to the right on the display, Y increasing upwards) is a synonym for BackView. XZView (X right, Y up) is a synonym for TopView, and ZYView (Z right, Y up) is a synonym for RightView. The light and camera views look through the selected light and camera. The schematic view is a diagram of the parenting hierarchy.
ViewLayout nlayout
PreviousViewLayout
NextViewLayout
SingleView
Select a view layout, the arrangement of up to four view panes. The layout indexes are

SingleView is a synonym for ViewLayout 0.

SaveViewLayout
Make the current view layout the default.
Layout_SetWindowPos nX nY
Scene_SetWindowPos nX nY
Item_SetWindowPos nX nY
Set the position of Layout's main window and the Scene Editor and Item Properties panels. The arguments are the screen coordinates of the upper left corner.
Layout_SetWindowSize nwidth nheight
Scene_SetWindowSize nwidth nheight
Set the dimensions of Layout's main window and the Scene Editor panel.
HideToolbar
Toggle the visibility of the toolbar (the vertical strip of buttons next to the view area).
AddButton scommand sgroup
Add a button to the toolbar or one of the other menu areas. The group is the name of the menu group in which the button will be added.
AlertLevel nlevel
Set the alert level. This controls the method used to display warning, error and informational messages. The level can be any of the values returned by the Interface Info alertLevel function.
AutoConfirm non_off
Set the auto-confirm switch. When this is turned on, confirmation dialogs that would otherwise be displayed to the user are suppressed. Plug-ins can use this to issue a large number of commands without inundating the user with requests to confirm each operation. Remember to turn it off again when you no longer need it.

Tools

These enable specific tools. Once a tool is active, the user's mouse movements and button clicking are interpreted as operations of the tool. These are available as commands primarily so that the user can map them to shortcut keys, but a few of the commands (Reset, for example) use the active tool as a context.

MoveTool
RotateTool
SizeTool
StretchTool
SquashTool
MovePivotTool
RotatePivotTool
MovePathTool
MorphAmountTool
RestLengthTool
ConeAngleTool
CameraZoomTool
AdjustRegionTool
LightIntensityTool
ChangeTool

Panels

These commands open or close panels.

EditServer sclass nindex
LastPluginInterface
Display a plug-in's interface. The class is the first field of the plug-in's ServerRecord, and the index refers to the list of applied servers of a given class. The first server in each list has an index of 1. Use the Item Info global to examine each item's server lists.
