VR Expansion Plugin

Hi, just starts with Unreal and try development to VIVE and watch that plugin. I have dowload last template. Migrated VIVE character to my one, copy the plugin folder and default input for controllers and the project opens without trouble, but can’t grip objects at all. For example in the template I add a cylinder or simple static mesh, activate simulate physics and works, but in my proyecto no, what I’m missing?
