Problem with line trace by channel in First person character

I have a problem with line trace by channel… I need the line goes to the same place as the camera, but it’s doesn’t work.
The line direction is always the same. It does not matter in the direction that the camera rotates.

Here’s my blueprint on First Person Character:

And this is the result…

Any idea?
Thank’s.

Try multiplying your forward vector instead of adding.
