You can create it with nodeboxes. There was one mod in the forum that had grass hills. Maybe you can use this. Or you maybe want to use stairs.

ok

the vanesaE home-decor mod adds slides in black white red brown and orange

They're roof shingles actually - asphalt (black), glass (white-ish), wood (brown), and terracotta (reddish orange).

I thought that mod just provided rail-like grass, so you are still stuck needing the top and bottom to make it turn into a rail:

AFAIK, there is no way to make a rail-like node without it being attached to the top and bottom to form the diagonal.

PilzAdam suggested a nodebox, which will work, but you will have tiny squares instead of a flat diagonal.

Yes, it is only railllike grass in my mod.
