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.

An optional input to import scene data.

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

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.

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.

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.

The type of constraint:

Look At - Allows your constrained prim to always face and look at the target prim you are constraining to.

Parent - Modifies the prim’s transformation as if the target was the parent hierarchically. Allows your constrained prim to match the translation, rotation and scale of the target prim and allows you to set whether you want that transformation to be absolute or relative to the constrained prims existing location in world space, using the maintain offset knob.

Transformation - Matches the location, rotation and scale of the prim to the those of the target. Acts similarly to the Parent constraint but is a quick way to constrain via translation or rotation.

Translation - Matches the location transformations of the prim to that of the target.

Rotation - Matches the rotation transformations of the prim to that of the target .

Scale - Matches the scale transformations of the prim to that of the target.

If enabled, extract the prim’s parent Xform. If the ‘Combine With Parent’ control is enabled this control is ignored.

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.

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

• Geo to Set your geometry to a vertex selection within the scene.

• Geo to Set your geometry to a vertex selection within the scene in a frame range.

• Geo to Snaps your geometry by using a custom script.

• Pivot Point to Set your pivot point to a vertex selection within the scene in a frame range.

• Pivot Point to Set your geometry to a vertex selection within the scene in a frame range.

• Pivot Point to Set your geometry to the selected prim’s bounding box within the scene. Click knob to select which part of the bounding box to snap to.

• Pivot Point to Snaps your pivot point by using a custom script.

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.

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.

If enabled an external scene file is used to retrieve prim attribute data, overriding the scene input connection which is ignored.

If a valid source prim path specified that prim’s attribute data will be ‘live’ pulled into the node’s parameters - not baked into knob curves.

A valid path to the input prim must be specified otherwise the node will produce an error.

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.

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.

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.
