Hi

I am trying to use the hills blocks in Valley but most of the other blocks do not interact - I managed to put some forests or a field but cannot use water bodies and many of the road blocks just do not cooperate - Is it me or are the hills more or less just ofr some background hiding ?

pics would be nice on what you trying to do, but if you trying to make a road come down a hill ?
nope its not going to work, unless you use the blocks with roads built in the large cliffs..
very limited roads on hills got to use the road block to make bridge then then banked blocks, but no roads work down hills, which i was let down with as well

hope that helps some how ^^

Water can only be placed on the lowest plane, so not on any hills unfortunately.
