## NAME

usdchecker - manual page for usdchecker 26.11.1

## SYNOPSIS

**usdchecker** \[*OPTIONS*\] \[*inputFile*\]

## DESCRIPTION

Utility for checking the compliance of a given USD stage or a USDZ package.  Only the first sample of any relevant time-sampled attribute is checked, currently.

### Positionals:

- inputFile FILE

  Name of the input file to inspect.

## OPTIONS

- **-h**,--help

  Print this help message and exit

- **--includeKeywords** KEYWORDS

  If specified, only validators from the included keywords are run. Multiple keywords can be specified as a comma separated list. If not specified, all validators are run.

- **-s**,--skipVariants

  If specified, only the prims that are present in the default (i.e. selected) variants are checked. When this option is not specified, prims in all possible combinations of variant selections are checked.

- **-p**,--rootPackageOnly

  Check only the specified package. Nested packages, dependencies and their contents are not validated.

- **-o**,--out FILE

  The file to which all the failed checks are output. If unspecified, the failed checks are output to stdout; if "stderr", terminal coloring will be suppressed.

- **--noAssetChecks**

  If specified, do NOT perform extra checks to help ensure the stage or package can be easily and safely referenced into aggregate stages.

- **-d**,--dumpRules

  Dump the enumerated set of rules being checked for the given set of options.

- **-v**,--verbose

  Enable verbose output mode.

- **-t**,--strict

  Return failure code even if only warnings are issued, for stricter compliance.

- **--variantSets** TEXT ...

  List of variantSets to validate. All variants for the given variantSets are validated. This can also be used with **--variants** to validate the given variants in combination with variants from the explicitly specified variantSets. This option is only valid when using the new validation framework.

- **--variants** TEXT ...

  List of ',' separated variantSet:variant pairs to validate. Each set of variants in the list are validated separately. Example: **--variants** foo:bar,baz:qux will validate foo:bar and baz:qux together but **--variants** foo:bar **--variants** baz:qux will validate foo:bar and baz:qux separately. This can also be used with **--variantSets** to validate the given variants in combination with varuants from the explicitly specified variantSets. This option is only valid when using the new validation framework.

- **--disableVariantValidationLimit**

  Disable the limit set to restrict the number of variants validation calls. This is useful when the number of variants is large and we want to validate all possible combinations of variants. Default is to limit the number of validation calls to 1000. This option is only valid when using the new validation framework.
