An optional Axis node input. This links the position, rotation, scale, and skew of the transformed 3D object(s) to the Axis node, so that the transformation controls on the Axis node override the corresponding controls on this node.

If you’ve worked with other 3D applications, you may know the Axis node as a “null” or “locator” object.

When disabled, the camera is configured using the controls under Local Xform on the Camera tab. Enable Import Scene Prim if you want to read in camera information from a file or from the scene graph.

When Import Scene Prim is enabled, determines where the camera is loaded from:

• File Path - a file on disk specified by the File Path control.

• Scene Input - a scene graph location specified by the Import Prim Path control.

Click to reload the camera information from the specified file or scene graph location.

Warning:  Any local changes you have made are overwritten by the imported camera data when you click Reload.

Sets the file path from which you intend to import camera information, if the scene input is not connected.

Sets the absolute scene graph path to the prim from which to import camera data.

Sets the scene graph path for the new camera prim, such as /Scene/Cameras/Camera1.

If the output path is left blank, the node name is used with a preceding / (forward slash). For example, /Camera1.

Sets the type of prim to create if there are missing ancestors in the path.

Note:  Setting the Parent Type to None may cause some referenced objects to behave as if they don't exist.

When enabled, this node does not create output prims or affect the incoming scene file or scene graph.

Any controls affecting output transforms still affect direct node connections, but those transforms are not output to prims in the output scene.

A simple use case for passthrough might be importing a transform from an input prim and modifying or re-parenting the transform using the axis input or Local Parent Xform controls without affecting the source prim.

When enabled, the input scene is merged with this node's output scene.

Note:  If the output prim path matches an existing path in the input scene, this node overwrites the existing prim.

When enabled, only the frame specified in the read_frame control is read.

When disabled, all frames are read.

When lock_read_frame is enabled, specify the frame number to read or use the read_frame animation control to read any frame speed curve.

When enabled, only the view specified in the read_view control is read.

When disabled, all views are read.

When lock_read_view is enabled, specify the view to read.

Sets the origin of the incoming frame range. Any frame rate change is scaled from this point allowing it to remain unchanged on the output frame slider.

This can be very useful to keep an important frame in a time-warped range from shifting unexpectedly on the timeline. For example, if shot animation begins at frame 101, but there are some preroll keys at frames 50-100, then setting this control to 101 keeps that frame from changing when a frame rate change is applied, preserving the start of the shot.

Sets the frame rate (frames per second) used to sample the geometry file.

If this rate is lower than the rate encoded in the file, animation is slowed down. For example, if the file was animated at 24 fps and Rate is set to 12, the animation is read at half speed.

Offsets the incoming keyframes in time by the number of frames specified. The offset is applied after any frame rate change.

The offset shifts the final, possibly time-warped keyframes in the frame slider.

Sets the preferred order of the output transformation operations when decomposing an imported matrix transform.

Sets the preferred order of the output rotation operations when decomposing an imported matrix transform.

When enabled, import the specified translation, rotation, and scale curves.

When disabled, ignore the specified translation, rotation, and scale curves.

When enabled, check for possible Euler flips in the decomposed rotation curves and remove them.

The Euler filter can help to avoid discontinuity in rotations.

When enabled, loading xform prim data inserts the prim's parent transform in the local-parent TRS controls.

When disabled, the parent transform is combined with the prim's local transform and placed in the Local Xform TRS controls.

Local Parent Xform

When enabled and Import Scene Prim is enabled, sync the Local Parent Xform controls to the imported scene prim data, destructively overwriting any user-assigned values.

When disabled the Local Parent Xform controls are not overwritten and remain available for user-assigned values.

Applies translation prior to the local transform allowing a parenting hierarchy to be kept separate from the local transform. The transform is applied in fixed SRT transform order and XYZ rotation order.

When loading xform prim data from a scene file, the prim's parent transform can be placed here.

Applies rotation prior to the local transform allowing a parenting hierarchy to be kept separate from the local transform. The transform is applied in fixed SRT transform order and XYZ rotation order.

When loading xform prim data from a scene file, the prim's parent transform can be placed here.

Applies scaling prior to the local transform allowing a parenting hierarchy to be kept separate from the local transform. The transform is applied in fixed SRT transform order and XYZ rotation order.

When loading xform prim data from a scene file, the prim's parent transform can be placed here.

Local Xform

When enabled and Import Scene Prim is enabled, sync the Local Xform controls to the imported scene prim data, destructively overwriting any user-assigned values.

When disabled the Local Xform controls are not overwritten and remain available for user-assigned values.

Select to import or export a channel file:

• Import chan file - import a channel file and transform the object according to the transformation data in the channel file. Channel files contain a set of Cartesian coordinates for every frame of animation in a given shot. You can create and export them using Nuke or 3D tracking software, such as 3D-Equalizer, Maya, or Boujou.

• Export chan file - export the translation parameters that you’ve applied to the object as a channel file. This is a useful method of sharing setups between artists.

Choose what a selection in the Viewer or pivot point is snapped to in the Viewer:

• Geo to Selection (position) - the object is snapped to a new position depending on the points selected.

• Geo to Selection (position, orientation) - the object is snapped to a new position and orientation depending on the points selected.

• Geo to Selection (position, orientation, size) - the object is snapped to a new position, orientation, and size depending on the points selected.

• Pivot Point to Selection (position) - the pivot point is snapped to a new position depending on the points selected.

• Pivot Point to Selection (position, orientation) - the pivot point is snapped to a new position and orientation depending on the points selected.

• Pivot Point to Selection (orientation) - the pivot point is snapped to a new position, orientation, and size depending on the points selected.

Sets the operation order for scale (S), rotation (R), and translation (T). The possible operation combinations are SRT, STR, RST, RTS, TSR, TRS.

Sets the order of rotation. The possible axial combinations are ZXY, XYZ, XZY, YXZ, YZX, ZXY, ZYX.

Lets you translate the object along the x, y, and z axes. You can also adjust translate values by clicking and dragging the object in the 3D Viewer.

Lets you rotate the object around the x, y, and z axes. You can adjust rotate values by holding down Ctrl/Cmd and dragging in the 3D Viewer.

Lets you scale the object on the x, y, and z axes.

Lets you scale the object simultaneously on the x, y, and z axes.

Lets you skew the object on the x, y, and z axes.

When you make changes to a 3D object’s position, scaling, skewing, and rotation, these occur from the location of the object’s origin point or pivot. The pivot translate and rotate x, y, and z controls allow you to move and rotate the pivot point as required - you can even move it outside of the object. Subsequent transformations applied then occur relative to the new pivot point location and rotation.

You can hold down Ctrl/Cmd and drag the pivot point to a new location in the 3D Viewer.

Pivot Rotate

Local Matrix

Enable this control to specify matrix values for the object you’re transforming as an alternative to setting transform, scale, skew and pivot values above.

The matrix displays values from the object’s transform, rotate, scale, skew, and pivot controls.

Check Specify Matrix and copy or drag-and-drop matrix values from another object to apply those values, for example, if you wanted to align objects in a scene.

World Matrix

Displays the world or absolute xyz transform of the node in world coordinates.

Note:  Unlike the Local matrix, you can’t adjust the World matrix manually.

Adjust the display characteristics of the 3D object. These settings don’t affect the render output of the scene; these are for display purposes only in the 3D Viewer.

• off - hides the 3D geometry object.

• wireframe - displays only the outlines of the object’s geometry.

• solid - displays all geometry with a solid color.

• solid + wireframe - displays the geometry as solid color with the object’s geometry outlines.

• textured - displays only the surface texture.

• textured + wireframe - displays the wireframe plus the surface texture.

Note:  The Viewer node 3D > display setting overrides this control.

When on, you can make selections as normal in the Viewer. When disabled, points cannot be selected or changed.

When on, you can edit points as normal in the Viewer. When disabled, points cannot be edited.

When off, the camera representation in the Viewer scales with the scene so that it's always visible.

When on, the camera representation in the Viewer is drawn at an approximate real world size and does not scale, so that the camera doesn't obscure other objects in the scene.

Sets the camera projection type when projecting 2D textures:

• perspective - objects in front of the camera have the illusion of depth defined by the camera's focal-length and aperture.

• orthographic - objects are viewed using parallel projection.

• uv - every object renders its UV space into the output format. Use this to cook out texture maps.

• spherical - the entire 360° world is rendered as a spherical map.

Sets the scale value to convert world-space units to meters for use in lens calculations to map into world-space units such as depth of field calculations.

Lens parameters like Focal Length and Horizontal and Vertical Aperture are defined in millimeters so this scale value is further divided by 1000 to get the final world-scale to millimeters scalar.

Sets the distance (in mm) between the lens and the point where the rays converge after having been refracted by the lens. Together with the Horizontal Aperture value, this determines the field of view angle.

Shorter focal lengths increase the field of view angle, capturing more of a given scene.

Sets the an equivalent width (in mm) to the film negative in a real camera.

Sets the an equivalent height (in mm) to the film negative in a real camera.

Adjusts the position, in scene units, of the camera’s near clipping plane. Objects closer to the camera than this plane are not rendered.

Note:  The value for the Near clipping plane must always be positive to produce a sensible result.

Adjusts the position, in scene units, of the camera’s far clipping plane. Objects farther from the camera than this plane are not rendered.

Changes the position of the film negative without changing the position of the camera itself, providing unique perspective views not otherwise possible. The value is in the range [-1,1] and it's relative to the film size.

Scales the film negative.

Rotates the film negative (by degrees) without changing the camera axis rotation itself.

Sets the distance in scene units from the camera center at which the image is perfectly in focus. Only applies to depth of field rendering.

As in real world camera, fstop controls the amount of light that can reach the film negative. Only applies to depth of field rendering.

Sets how long the shutter should be open for when blurring motion. The value is in frames, so 0.5 is half a frame.

Controls how the shutter behaves with respect to the current frame value. It has four options:

• centred - centers the shutter around the frame. That is, open from f - shutter/2 to f + shutter/2.

• start - opens the shutter starting at the frame. That is, open from f to f + shutter.

• end - closes the shutter at the frame. That is, open from f - shutter to f.

• custom - opens the shutter at the time specified by the shuttercustomoffset control.

When shutteroffset is set to custom, this controls the time that the shutter opens by adding it to the current frame.

Values are in frames, so -0.5 would open the shutter half a frame before the current frame.
