Transform Item#

Transform Item

The Transform Item tool is designed to greatly speed up set dressing and layout work by reducing the number of operations and mouse clicks needed to position items on a set.

Developed to ease the workflow of environment and generalist artists alike, the Transform Item tool is a single streamlined tool that lets you translate, rotate, scale and snap your selection faster and more efficiently than ever before. This manipulator is bound to the T key

To translate a selection just click-drag on one of the translation axis. The axis will highlighted in yellow when hovering over it.

Use Middle Button to move the item through the normal plane of the selected axis. Middle-clicking to center square will move the item through the normal plane of the view.

To rotate a selection just click-drag on one of the arcs. The arc will highlighted in yellow when hovering over it. If you click-drag on the inner circle, you can perform a trackball like rotation whereas if you click-drag on the outer circle, you will rotate the item in the view axis.

To scale a selection just click-drag on the little cube displayed on the axis. The cube will highlighted in yellow when hovering over it. Use Middle Button to scale the items through the normal plane of the selected axis. click-drag on the center cube to scale on all axis at once.

Pressing Esc while dragging cancels the action.

It is possible to hide/show the manipulator by pressing X. Pressing O offsets the manipulator to the center of the selection, M repositions the manipulator under the mouse cursor and P resets the manipulator offset.

Like the Select tool, it is possible to use the Transform Item to manage selections. Please refer to the Select tool for more information. This tool also offers a comprehensive set of snapping functions. For more information please refer to Snapping.

To access to more options use the Tool Options widget or double-click on the tool icon in the toolbar. Using the preferences panel, it is possible to set the default behavior of the manipulator options. Go to Edit > Preferences... > Layout.

Skip Children Skip children transformation update in case both parent and children are manipulated together.
Manipulator Interest Center Set the position of the rotate manipulator in world space when Space is set to Manipulator.
Manipulator Display Offset Set a display offset of the manipulator
Align To Normal When enabled, the rotation of the selection is modified so that the item is aligned on the underlying normal when snapping on a surface.
Snap Default Plane Select default plane to snap on when mouse cursor doesn't target any items when snapping.
Snap Distance Set the distance in screen space to search for nearby vertices when performing vertex snapping.
Translate Snap Enabled Enable grid snapping.
Translate Snap Increment Set the snap increment of the tool in all axis. This basically controls the size of the snapping grid unit.
Rotate Snap Enabled Enable rotation value snapping.
Rotate Snap Increment Set the snap value increment of the tool in all axis.
Scale Snap Distance Enable scale value snapping.
Scale Snap Increment Set the snap value increment of the tool in all axis.

Manipulating Item Offsets and Pivots#

Using the Transform Item it is possible to edit the translate, rotation and scale offsets of the items at once without changing the transformation of the selection.

Press Ins key to enter the offset edition mode. Alternatively, you can set the Mode option to Offset using the Tool Options widget.

When in Offset/Pivot edition mode, the handles of the gizmo are displayed as dashed lines. If you press Ins a second time, you will enter the pivot edition mode to set the rotation and scale pivot point. It is also possible to enter the pivot edition mode by setting the Mode option to Pivot. Pressing Ins a third time returns to the Transform mode.

Manipulator Space#

It is possible to control in which space manipulators are expressed. By default, they are set to Parent to reflect the attribute values of the items which are expressed in parent coordinates.

Space Description
Object Set the manipulator in object coordinates.
Manipulator Set the manipulator in its own coordinates system.

When space is set to Manipulator, you have access to the Manipulator Initialization group of options in the Tool Options widget. It defines how the tool is initialized when the selection is changing. You can specify the initialization behavior for single selections and multi-selections.

Single Selection mode / Multi Selection mode Description
Unchanged The manipulator stays in place
World Origin The manipulator stays at the world origin
Object Pivot / Last Selected Pivot The manipulator is placed at the pivot location of the selected object
Object Bounding Box Center / Selection Bounding Box Center The manipulator is placed at the center of the bounding box
Object Bounding Box Ground / Selection Bounding Box Ground The manipulator is placed at the bottom center of the bounding box

Look at Surface#

Like the Rotate Item tool, it is possible to orient the selection to a surface by pressing K + click-drag as if they were constrained to a Target constraint. This feature is very handy when it comes to orient lights.
