I was having a difficult time trying to get terra forming to work the way I wanted to.
No matter what you do, you can NOT get a really steep slope when terra forming. So I’ve decided to do the next best thing, build a retaining wall!
I highly recommend using the Move Placeables mod to help you get this in the right spot. you can find it on the in-game mod hub, or here: Move Placeables
I also recommend using a save game you dont care about to learn how to effectivly use this mod. Play around with it first to get used to how to set it up, so you dont destroy a good save game file.
I might make a video to better show you how to use the Move Placeables mod with this to get the results you want.
Only 2 warnings about mod icons and mips (I’ll work on this later) Collisions are present, so you wont clip through the top or the sides.
As always, Feedback is welcome, and I hope you enjoy!
