Unigine::Import Class

Warning
The functionality described in this article is not available in the Community SDK edition.
You should upgrade to Engineering / Sim SDK edition to use it.
Header: #include <UnigineImport.h>

This is an import manager class. It is used to create and manage importers, processors as well as to directly import files in non-native formats, if an importer for such files was previously registered.

You can manage the set of available importers dynamically by adding them to or removing from the registry.

Each importer has a unique identifier (or ID) represented by the ImporterID structure combining the following values:

  • Vendor Name - name of a company or person offering the importer.
  • Importer Name - name of the importer (e.g. there can be multiple importers having the same name FBXImporter but offered by different vendors).

Each importer has a priority index indicating the order in which it will be used for processing files among other available importers registered for the same file extension (an importer with higher priority value among others available shall be used).

You can also get the list of all currently supported file extensions or a list of all file extensions supported by a specific importer.
