AvatarStaging framework consists in directing avatars on a mixed theatrical stage, enabling a co-presence between the materiality of the physical actor and the virtuality of avatars controlled in real time by motion capture or specific animation players. It led to the implementation of the AKN_Regie authoring tool, programmed with the Blueprint visual language as a plugin for the Unreal Engine (UE) video game engine. The paper describes AKN_Regie main functionalities as a tool for non-programmer theatrical people. It gives insights of its implementation in the Blueprint visual language specific to UE. It details how the tool evolved along with its use in around ten theater productions. A circulation process between a nonprogramming point of view on AKN_Regie called Plugin Perspective and a programming acculturation to its development called Blueprint Perspective is discussed. Finally, a C++ Perspective is suggested to enhance the cultural appropriation of technological issues, bridging the gap between performing arts deeply involved in human materiality and avatars inviting to discover new worlds.

翻译：AvatarStaging框架的核心在于指导混合舞台上的虚拟化身，实现物理演员的物质性与由动作捕捉或特定动画播放器实时控制的虚拟化身之间的共存。该框架促使AKN_Regie创作工具的实现，该工具使用蓝图可视化语言编程，作为虚幻引擎（UE）视频游戏引擎的插件开发。本文描述了AKN_Regie作为非编程戏剧从业者工具的主要功能，并阐释了其在UE特有的蓝图可视化语言中的实现细节。本文详细阐述了该工具如何随着约十部戏剧作品的使用而演进。文中讨论了从非编程角度审视AKN_Regie的“插件视角”与从编程文化适应角度看待其开发的“蓝图视角”之间的循环过程。最后，提出“C++视角”以增强对技术问题的文化适应力，从而弥合深植于人类物质性的表演艺术与引领人们探索新世界的虚拟化身之间的鸿沟。
