Static mesh didn't detect by line trace by channel


I make a 3D action game project, I try to use the blueprint “Line Trace by channel” to detect when the line hit a static mesh

As this topic said : Spawned static mesh does not use static mesh's trace responses - UE4 AnswerHub

It’s seems that line didn"t hit a static mesh object, (it’s detect simple shape like cube) , I follow the instruction like put blockAll for the static mesh but it’s still didn’t work, and the line trace channel is camera

I attach the picture on this topic

Thanks !

ANy ideas ?
