I agree with Lord Tony and Mr.Noßody. Foliage is indeed a whole another things. You are supposed to have a lot of cacti, trees, bushes, flowers and such. Sure you can easily build a few of them but say you wanna make a forest. It eats tons of bricks that I bet you would much rather use for something more important. I would like to see a tree brick pack with several different trees that look like they were built with bricks.
Are you serious?
As long as people provide me with saves of well built foliage I can provide .obj files to anyone wanting to make them into bricks.
Tell me if you want the Build.
