Creating new worldspace same as in Skyrim?

[YouDoNotKnowMyName]

Good evening!

 

I have actually started working on a (little) project that will include a (small) custom worldspace.

I haven't really found any "Heightmap to Fallout 4 worldspace" tutorials, but I found one for Skyrim:

http://tambomedia.com/Site_Pages/tutorials/L3DT.html

The "workflow" is basically as follows:

1. Create landscape in L3DT
2. exort as .RAW image file
3. put it through TESAnnwyn
4. Add masterfile with TESedit
5. do some stuff in the CK

I already (kind of) have the greyscale heightmap, so I will just import that into L3DT to then adjust the max / min height of the landscape and to export it as a .RAW file.

So that part is clear.

But what i don't know is if TESAnnwyn works with Fallout 4.

TESAnnwyn takes the heightmap of the landscape and somehow creates a .esp file that contains a worldspace based of of the heightmap.

Officially this program only supports Morrowind, Oblivion, Fallout 3, Fallout NV and Skyrim.

So can I use a esp that was created with TESAnnwyn with the Fallout 4 CreationKit?

Or if not, is there any other way to create a worldspace landscape from a heightmap in the Fallout 4 CreationKit?

 

Thanks
