A bit selfish request but even it is not supported if server using hybrid software (spigot + forge) and ModelEngine (rendering models using display entities) modelengine animations will lag and completly destroys bone system while using with citadel so, making this fixes the issue I think. I will try to implement and create a PR.

有点自私的请求，但即使它不受支持，如果服务器使用混合软件（spigot + forge）和 ModelEngine（使用显示实体渲染模型），modelengine 动画将滞后并在与 citadel 一起使用时完全破坏骨骼系统，所以，我认为这可以解决问题。我会尝试实施并创建 PR。

Have you solved this problem?
