This study reports extensions to the OAR （OpenSimulator Archives） Converter, a tool for converting OpenSimulator OAR files into formats compatible with Unity and Unreal Engine 5（ UE5）. The new version supports Unity 2022 and later, WebGL delivery, and UE5 imports via OBJ and glTF. It also embeds Bento-compliant joint data in COLLADA and glTF files, enabling avatar motion in game engines. In addition, encoding attribute information in material names suppresses redundant textures. In measurements on 32 OARs, the number of imported entries decreased substantially, and the entry count showed strong rank correlations with Unity import time and elapsed time. These capabilities enable practical applications such as web-deployable demos, remote and in-class instruction, museum/exhibition experiences, and are expected to promote efficient sharing and reuse of research and educational assets.
