在这门Epic在线学习课程中，我们将探索虚幻引擎中的动画系统。首先，我们将学习动画的导入、重定向和剪切，以便在状态机中使用这些动画。然后，我们将利用混合空间来混合动画，用混合空间分析来解决滑步等问题。我们还将学习如何利用插槽（Socket）将物体附加到控制绑定上；如何用动画蒙太奇插槽（Slot）覆盖动画；如何用控制绑定和Sequencer编辑现有的动画，再将它们烘焙出来（仅需使用虚幻引擎处理！）。

You CAN NOT understand many of the course unless you are familiar with UE animation system. Funny.
good tutorial to cover the basic of animation ecosystem, but does not introduce what is control rig, the ik bone that kind of thing. last lecture is not that easy, i try to follow and delete some frame as the tutorial, but still give me bad result, can’t actually get smooth result, something is missing on the curve tool.
