Line trace help

Hey guys not sure why this code doesnt work

what im trying to do is do a line trace from the camera boom base but this does not seam to work.
thanks guys

Dont use Relative Location and Rotation, because those are always 0,0,0 or 40,50,60 or something like that because they are relative to the location of his parent. Use World Location and Rotation of the camera and will works

How do i get the world Location and Rotation of the camera boom?

GetComponentLocation() / GetComponentRotation()

Just dig through the intelli sense documentation, they have done a pretty good job with that.
