Virtual Production (VP) professionals often face challenges accessing tacit knowledge and creative intent, which are important in forming common ground with collaborators and in contributing more effectively and efficiently to the team. From our formative study (N=23) with a follow-up interview (N=6), we identified the significance and prevalence of this challenge. To help professionals access knowledge, we present GroundLink, a Unity add-on that surfaces meeting-derived knowledge directly in the editor to support establishing common ground. It features a meeting knowledge dashboard for capturing and reviewing decisions and comments, constraint-aware feedforward that proactively informs the editor environment, and cross-modal synchronization that provides referential links between the dashboard and the editor. A comparative study (N=12) suggested that GroundLink help users build common ground with their team while improving perceived confidence and ease of editing the 3D scene. An expert evaluation with VP professionals (N=5) indicated strong potential for GroundLink in real-world workflows.

翻译：虚拟制作（VP）专业人员常面临获取隐性知识与创作意图的挑战，这些要素对于与协作者建立共识、更高效地为团队做出贡献至关重要。通过我们的形成性研究（N=23）及后续访谈（N=6），我们确认了这一挑战的普遍性与重要性。为协助专业人员获取知识，我们提出GroundLink——一款Unity插件，可将会议衍生的知识直接呈现在编辑器中以支持共识建立。其功能包括：用于记录与回顾决策意见的会议知识仪表板、主动向编辑环境提供信息的约束感知前馈机制，以及建立仪表板与编辑器间参照链接的跨模态同步系统。一项对比研究（N=12）表明，GroundLink能帮助用户与团队建立共识，同时提升编辑3D场景时的感知信心与操作便捷性。由VP专业人员参与的专家评估（N=5）显示，GroundLink在实际工作流程中具有显著应用潜力。
