## Geometry Import Settings

Depending on the type of import, some of the options differ.

Import Type box
  Select the 3D model type to import.

File Extension field
  Displays the default extension for the file type selected in the Import Type box.

Smooth button
  Enable to build normals for the 3D model. Enable if you are importing polygons that do not have normals.

Auto Fit In Scene button
  Enable to scale the imported model to fit into the current frame. When disabled, the imported model maintains the same size in which it was created.

Mesh Animations button
  Enable to import the Alembic scene animations and preserve complex geometry animations.

Normal button
  Enable to import an Alembic model's normal information.

Separate Nodes button
  Enable to create individual nodes for all 3D models contained in a file. When disabled, the 3D model is added to the scene with its own axis.

Rotate Axis button
  Enable to rotate the 3D model by 90 degrees on the X-axis so that it is compatible with the target's coordinate system.

Create Media button
  Enable to load the textures of the geometry to the Media list. If a texture is used in multiple geometry maps, it is loaded only once in the Media list.

## Timing Settings

Animation Mode box
  Select the animation mode to use for multiple 3D geometries imported into a single animated geometry node.

  Select: | To:
  --- | ---
  Loop | Play in a continuous loop.
  Once | Play once. The 3D geometry is no longer displayed.
  Last Still | Play once, and hold the last frame.
  Timing | Animate according to the timing in the animation channel.

Hold field
  Displays the number of continuous frames for Loop, Once, or Last Still Animation modes. Editable.

Slip field
  Displays the offset to the start point for Loop, Once, or Last Still Animation modes. Editable.

Timing Range option box
  Select an option to determine how Frame Timing values outside the timing range of the animation are handled. Available when Timing is selected in the Animation Mode box.

  Select: | To:
  --- | ---
  Roll | Roll over the Frame Timing value.
  Cut | (Geometry is not displayed.)
  Round | Display the first or last geometry (with this option, you can select the first and the last geometry of your animation).

Frame Timing field
  Displays the value for the frame in the timing curve. Available when Timing is selected in the Animation Mode box. Editable.
