Hi Dave, Bilboard trees are for the ''transfer'' from ts2012 which I have to replace Pofig's trees with any tree that will show up in T:ANE, then after that I will replace bilboard trees with 3d trees when I find nice ones which seems to be McGuirel's or maybe Jankvis's ....but they are not officially available actually.I would never use Billboard trees. A step backward IMHO. I know that Pofig's wonderful trees don't work in T:ANE but I'm pretty sure there are other options.
