This is a Cine Camera Component where you can reference or link to an external camera placed within your level or project. This component creates the inner frustum necessary for in-camera VFX projects.

简单来说，ICVFX就像一个WeakPtr，引用的是场景里的某个CineCamera。ICVFX用于创建一个【内视锥】。这个“内”是相对于ScreenComponent定义的视锥体来说的。ICVFX是虚拟拍摄的真正画面来源。

我注意到ICVFX应该是in-camera VFX的简写。
