usdstitch

usdstitch aggregates any number of usd files into a single file. This process is different from flattening a stage . The key differences are:

• The result of usdstitch will contain the ordered union of Composition Arcs present on prims in the input sequence of files, whereas usdcat --flatten removes (by evaluating or flattening the composed opinions) composition arcs.
• usdstitch merges the timeSamples from the input sequence of files, whereas flattening preserves the TimeSamples of only the strongest layer that contains TimeSamples, which is consistent with how Value Resolution interprets layered TimeSamples on a stage.
