Is there any way to see splines at runtime? Not seeing the splines makes it really hard to debug.
Did you have a Spline , in first place? Like a Blueprint Spline, for example… ?
Yea, I generate a spline at runtime and use it alongside with spline meshes. I had a issue were showing the spline would have helped me greatly to debug it.
Did you try to to check the “wireframe” mode? perhaps you give us a screenshoot in wireframe of the scene?
Well this is a really old but if anyone is still looking for an answer, You need to tick the “Draw Debug” option in the spline component properties panel
That is not working at runtime!
While playing the game, try to open up the console (using ~ “tilde”, under the Esc button) and try to write:
show Splines
(tested with 4.22.3 and older versions)
P.S. Just make sure that the showflag (Draw Debug) is set to true, as "Yashinski " showed on his screenshot 
(I’ve tried this only with the project set with its Build Configuration to Development. There is a big chance that it will not work for Shipping)

Oh, cool! Don’t need it for shipping anyway, just so I can actually see my splines for debugging purposes. Thanks! I can’t approve your answer so I just set Yashinski’s post as the answer
