Middle Mouse Button

The functionality of the middle mouse button in Modeler mirrors that of the stock Houdini. However, holding down the Ctrl key introduces a modification. Specifically, it triggers an automatic adjustment to the handle alignment preference under "Houdini Preferences/Handles/Translate Handle". If the current setting is "Drag in View Plane", pressing Ctrl temporarily switches it to "Map Drag to Axis". Conversely, if the setting is "Map Drag to Axis", pressing Ctrl changes it to "Drag in View Plane" for the duration that the Ctrl key is held down.

Cycle Handle Alignment

Modeler has no built-in Cycle Handle Alignment tool, but the Houdini version can be invoked with the M key. By default M is not assigned in Modeler.

Quick Pivot Tool

QuickPivot changes the position and orientation of most of transformation handles.

How to

• Be sure the tool state with handle is active
• Press the Quaick Pivot tool hotkey (D by default)
• Click on desired location with one of combinations of keyboard modifiers:
  • LMB – to place and rotate the handle based on picked component
  • Shift+LMB – to only rotate the handle based on picked component
  • Ctrl+LMB – to only move the handle based on picked component
  • Ctrl+Shift+LMB– to rotate the handle, so it will look at clicked component
  • To select handle axis click it with LMB. To select primary (normal) axis click it with Ctrl+LMB

Current Limitation:

• If you want to remap this tool's hotkey do not use hotkey with modifiers.

  For example, D is a good hotkey. But Shift+D will not work correctly.
