Thank you! I would have never gotten that. So just in case anyone ever cares, I replaced the DefaultSceneRoot with Beam01. I then added a socket to Beam02, shown here.
For beam03 I then selected the root, shown here.
And then changed the Construction script as follows.
This allows me to have a beam that I can bring in and change the length as I want, but it retains the details on the ends. I am free to rotate and just go nuts. Now for the texturing. I saw a thing on GDC 2016 where Cyan games made edge aware textures using this technique. Just FYI the slides are available for download even without a subscription. Unfortunately the slides don’t show the really cool texture at work. Just look for “Building Obduction: Cyan’s Custom UE4 Art Tools” on gdcvault.com
