Create or import GPU caches


You can create Alembic-based GPU cache files from the polygon or NURBS objects in your scene. You can save all the scene objects to a single cache or create a cache file for each selected object.

NoteLambert and Phong materials from the original geometry can also be saved to the GPU cache file. See Shade and render GPU caches.

To create a GPU cache

  1. Do one of the following:
  2. In the GPU Cache Export Options window, select a Cache time range option to specify which frames to cache.
  3. If you choose to save selected objects to separate caches, specify a File name prefix.

    By default, Maya adds the scene file name to the start of cache file names.

  4. (Optional) Change the default Optimize Hierarchy Optimization Threshold settings.

    These options optimize GPU caches for playback performance. The GPU Cache Preferences provide additional optimization options.

  5. (Optional) To have animated objects display with motion blur when played in Viewport 2.0, turn on Optimize Animations for Motion Blur.
  6. (Optional) To save the Lambert or Phong materials from the original geometry to the cache file, ensure Write Materials is on.

The materials render when the cache file is played back in Viewport 2.0. Write Materials is on by default.

  1. Click Export.

To import a GPU cache

  1. Select Pipeline Cache > GPU Cache > Import > .

    You can also import GPU cache files by selectingPipeline Cache > Alembic Cache > Alembic Import > . See Pipeline Caching Workflows.

  2. In the GPU Cache Import Options window, select from the following:
  3. Click Import.
