I've taken up the info from one of our members on Moddb "Don't use blocks" from Joure. At least for the boundarys of Nams Forest. Instead I am using Hl2 Ep.2 Fences. They work well and give you a better outlook on the rest of the map that is not supposed to be walked on or entered, or in a smaller summary, the background! Ill be uploading the Pictures Soon!
( Do still note that map has not been completed yet, but is alittle farther than last time).
Sounds good to me :)
