Is the line trace being fired? Don’t forget to turn on DrawDebugType to check 
I am building a VR software with UE4 and I want the user to be able to use the motion controllers to place an object in the world using a raytrace. If the user presses the trigger button and the measurement tool is selected, it calls the Measurement function as shown below.
How I intend the Measurement function to work is that if there are less than 2 Measurement Spheres (a different blueprint), it spawns a Measurement Sphere at the end of the raytrace using LineTraceByChannel. Here is what I have below so far.
Unfortunately, nothing happens when the trigger is pressed. Am I missing something or doing something not quite right?
Thank you for your help!

That worked! For some reason, the raytrace wasn’t firing
Yes! Thank you!
Spawning the actor works now?
Amazing! That was quickly solved. haha
