These ERF files contain modified CNR placables that use the new CEP models. Requires CNR 3.05, CEP 1.01, SoU, HotU & NWN patch 1.62. One for the trees and another for placables. You might want to check the placables if you import them into an already created module as some of the sizes differ. Some of the larger trees can be slightly hard to select if placed too close together.
