Set Mesh Error

Hello guys I have a problem setting my mesh when it is analyzed, when I put set mesh in my OBJ it does not work in my analysis but when I leave a standard mesh it works, I believe it is because it is not being captured, just when it is not set it captures, I made a video for better views ( BP on Vimeo ). I just have this doubt to be able to build my BP !!

NOTE: I created a BP Analyze a BP Item and a Widget
