getRelatedAssetId

void  getRelatedAssetId(
    const std::string& assetId, 
    const std::string& relation,
    std::string& ret
)

Find a related assetId from an arbitrarily defined relationship.

This allows Katana to find related assets from an existing assetId.

The relation argument is an arbitrary string. The only value Katana will provide is "argsxml" to help discover parameter information for procedurals that come from assetIds.

If the relationship is unknown, set ret to an empty string. Katana will fall back on its default behavior for "argxml" when ret is empty. This means Katana will search for the files it needs relative to the file path for the shared library. When this plugin does provide a value in ret, Katana will resolve the results and never fallback on relative file searches.
