There are several items that would be really nice to be attached to pillars - Wall signs, Radium Torches, Torches, etc.
Some can even completly attach optically - but cannopt be placed because “Not enough contact with wall”
Pillars would make excellent signposts, but since nothing can be attached…
If it helps, my LBPR mod will do what you ask now. I did it the “easy way” though, Funcom would have a more difficult challenge on their hands to do it the right way. Anyhoo, just thought I would share.
You can attach the torches and everything it’s just a very, very, very small line on the pillar. I don’t use the above mod and already have some trophies, torches and even a sign on them.
