在外部导入模型和引擎内部自带的静态网格物体中，无法找到调节面板中的flex，即使讲模型转换为FlexActor，也无法找到Flex
In the external import model and the static grid objects inside the engine, flex can not be found in the adjustment panel, and even if the model is converted to FlexActor, the Flex can not be found.
Me too，by the way，how did you change modle to FlexActor
