For example, passing +'-o output.usd --usdformat usda' will create +output.usd as a text file. The USD_DEFAULT_FILE_FORMAT +environment variable is another way to achieve this. + +.TP +\f[V]-l\f[R], \f[V]--loadOnly\f[R] +Attempt to load the specified input files and report 'OK' +or 'ERR' for each one. After all files are processed, this +script will exit with a non-zero exit code if any files +failed to load. + +.TP +\f[V]-f\f[R], \f[V]--flatten\f[R] +Compose stages with the input files as root layers + +.TP +\f[V]--flattenLayerStack\f[R] +Flatten the layer stack with the given root layer, and +write out the results. Unlike --flatten, this does not flatten +composition arcs (such as references). + +.TP +\f[V]--skipSourceFileComment\f[R] +If --flatten is specified, skip adding a comment regarding the +source of the flattened layer in the documentation field of the +output layer. + +.TP +\f[V]--mask\f[R] [PRIMPATH...] +Limit stage population to these prims, their descendants and +ancestors. To specify multiple paths, either use commas with no +spaces, or quote the argument and separate paths by commas +and/or spaces. Requires --flatten. + +.TP +\f[V]--layerMetadata\f[R] +Load only layer metadata in the USD file. +This option cannot be combined with either --flatten or +--flattenLayerStack + +.SH NOTES + +.TP +The multi-file input to usdcat does not perform any kind of merge of the content in the separate +files (and there is no such utility to do so,yet… parameterizing that problem is an interesting challenge!); +it simply dumps the contents of each file, sequentially. + +.TP +The \f[B]--flatten\f[R] option uses the stage \f[B]Export\f[R] , which, as one might expect, +“bakes in” the effects of all composition operators, simultaneously removing the operators themselves, +in the result; this applies both to namespace operators like references, sublayers, and variants, +and also to value-resolution operators like layer and reference time offsets. +Flattening a stage does preserve USD native instancing by flattening each prototype into the generated layer +and adding references on each instance to its corresponding prototype. +Thus, the exported data may appear structurally different than in the participating source files, +but should evaluate/compute identically to that of the source files.
