Axis nodes act as null objects by adding a new transformational axis to which other objects may be parented. Even when objects already have their own internal axes, it’s sometimes useful to parent in a separate axis. For example, when an Axis node is parented to other objects in a scene, the node globally controls the scene - rotating the axis rotates all objects in the scene.

unnamed |
You can only attach other Axis nodes to this input to create a hierarchy, rippling transforms downstream. |

read from file |
read_from_file |
disabled |
When disabled, the axis is configured using the controls on the Axis tab. Enable read from file if you want to read in axis information from an .fbx file using the File tab. NOTE: This control is linked to the read from file control on the File tab. |
display |
display |
wireframe |
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 + lines - displays the geometry as solid color with the object’s geometry outlines. • textured - displays only the surface texture. • textured + lines - displays the wireframe plus the surface texture. NOTE: The Viewer node 3D > display setting overrides this control. |
selectable |
selectable |
enabled |
When enabled, you can make selections as normal in the Viewer. When disabled, points cannot be selected or changed. |
|
file_menu |
N/A |
Select to import or export a channel file: • Import chan file - import a channel file and transform the objects attached to the Axis node 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 Axis node as a channel file. This is a useful method of sharing setups between artists. |
|
snap_menu |
N/A |
• Match selection position - the objects attached to the Axis are snapped to a new position depending on the points selected. • Match selection position, orientation - the objects attached to the Axis are snapped to a new position and orientation depending on the points selected. • Match selection position, orientation, size - the objects attached to the Axis are snapped to a new position, orientation, and size depending on the points selected. |
transform order |
xform_order |
SRT |
Sets the operation order for scale (S), rotation (R), and translation (T). The possible operation combinations are SRT, STR, RST, RTS, TSR, TRS. |
rotation order |
rot_order |
ZXY |
Sets the order of rotation. The possible axial combinations are ZXY, XYZ, XZY, YXZ, YZX, ZXY, ZYX. |
translate |
translate |
0, 0, 0 |
Lets you translate the 3D objects attached to the Axis node along the x, y, and z axes. You can also adjust translate values by clicking and dragging the axis in the 3D Viewer. |
rotate |
rotate |
0, 0, 0 |
Lets you rotate the 3D objects attached to the Axis node around the x, y, and z axes. You can adjust rotate values by holding down Ctrl/Cmd and dragging in the 3D Viewer. |
scale |
scaling |
1, 1, 1 |
Lets you scale the 3D objects attached to the Axis node on the x, y, and z axes. |
uniform scale |
uniform_scale |
1 |
Lets you scale the 3D objects attached to the Axis node simultaneously on the x, y, and z axes. |
skew |
skew |
0, 0, 0 |
Lets you skew the 3D objects attached to the Axis node on the x, y, and z axes. |
pivot |
pivot |
0, 0, 0 |
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 x, y, and z controls allow you to offset the pivot point and move it anywhere you like - you can even move it outside of the object. Subsequent transformations applied will then occur relative to the new pivot point location. You can also hold down Ctrl/Cmd+Alt and drag the pivot point to a new location in the 3D Viewer. |
Local Matrix |
|||
specify matrix |
useMatrix |
N/A |
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. |
matrix |
matrix |
N/A |
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 |
|||
World matrix |
world_matrix |
N/A |
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. |
File Tab |

read from file |
read_from_file |
disabled |
When disabled, the axis is configured using the controls on the Axis tab. Enable read from file if you want to read in axis information from an .fbx file. NOTE: This control is linked to the read from file control on the Axis tab. |
file |

N/A |
Sets the file path for the .fbx file from which you intend to import axis information. |
reload |
reload |
N/A |
Click to reload the axis information from the specified file. |
animation stack name |
fbx_take_name |
N/A |
When the file control is pointing to a valid .fbx file, select the required take name from the dropdown menu. |
node name |
fbx_node_name |
N/A |
When the file control is pointing to a valid .fbx file, select the required node name from the dropdown menu. |
frame rate |
frame_rate |
24 |
When use frame rate is enabled, enter the required frame rate to use instead of the rate specified in the input file. |
use frame rate |
use_frame_rate |
disabled |
When enabled, the frame rate from the input file is ignored and the specified frame rate is used instead. |
