EXPANDED COLLECTION HERE: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=487703034

This collection allows for sunken walls that can be used to contain highways, railways, or anything else! The walls will hide the cliff texture and allow for a very sharp-looking product. They also double as parks, and show up in this category.

Triangle counts are very low, under 50 for most if not all pieces.
Texture sizes are also very small (512x256) and utilize repeating textures.
The only known issue is that these assets look a little funny when zoomed out, despite custom LODs. If anyone can help solve this, I would appreciate it!

Stats:
