I think it should be possible to copy paste stuff like this, and I'd be willing to help with creating more as it's something that is really needed imo for some of the big (and small) caves we have in Moria.
@dav3ck do you think having a day devoted to making these Moria cave pillars and etc (like a build day) would be useful? Could really come out with a lot of work done. I want to start doing more bigger build events.
