Overview: This short tutorial shows how a feature tracked in Aura and exported as a LightWave motion file can be loaded to a null and automatically positioned properly against the original plate which has been placed as a background image in Layout.     Keyframes after tracking the feature in Aura.    The Aura Export dialog.  "Origin X" and "Origin Y" should be left at the default values, equal to the midpoint of the footage.  Turn "Reverse Y" ON.  Export the file. Before running TransMotion3D, load the background footage into LightWave.  In "Effects > Compositing" select the footage as the "Background Image."  In "Display Options" set the "Camera View Background" to "Background Image."  Add a null to the scene.  The motion tracked in Aura will be loaded to the null in the next step.  Make sure that the null is the current item, then run TransMotion3D. The TransMotion3D panel.  Select the file exported from Aura.  This file will be preserved unchanged and a new file will be created and named with "_tm3d" appended before the ".mot" extension -- but you may never notice this.  With "Load Motion File to selected item" checked the motion will be loaded automatically.  Set Ref. Image to the background footage.  Make the other settings as shown.      A new camera is created in LW and automatically positioned to match the motion against the background plate.
