Simple enough... Here are the steps : -make a 1024*1024 RAW 16Bits image with photoshop (1024*1024 is for a quad so supposedly 4096*4096 should be the max) -with TESAnnwyn (which you can find on google) importe it using TESAnnwyn -i 4 -w MyWorld -s 0.25 MYFILE.raw command (-s is a scale factor depand on contrast of you image, i used 0.4 but for know can't see the result since steam is still downloading textures pack) -with the CK create an empty worldspaces with the same name as specified with the -w command -withe TESVSnip (which you can find on nexus) add the esp made with Annwyn and the esp made with CK -Under WRLD in the annwyn esp you should find a GRUP item, copy them to your esp made with CK -SAVE -open CK, active your esp, DONE, ENJOY ! look at skyrim nexus since i can't make link if you search "Worldspace proof of concept" in the images sector. I've posted a screen of the new worldspace
I tried this but the only thing I get is a buggy heightmap, with misaligned cells (as an example, think of a really compressed JPEG image with uneven edges all over it) and exagerated tones (my heightmap's highest points are usually peaking between
purplish red (purplish red, z = 16 384) and
yellow (z = 24 576) since the highest tone value on my map is 170 on 255 (grayscale in Photoshop), but now they peak all the way up to
green (z = 57 344) and
grey (z = 65 535), exagerating all of the map's surface and its height). Plus, the new map is reflected upside-down (a bit like this : < | > , or like this : d | b , if you see what I mean). In my opinion, it has something to do with the Annwyn.esp being made for Oblivion and not Skyrim, but you say it worked for you, so I may be wrong. Maybe it has something to do with me not downscaling my heightmap trough TESAnnwyn (I didn't use the ''-s'' option, I just didn't typed it, since I was already Ok with my map's height proportions).
Here's some screeshots of the original and the buggy heightmap :

Could you provide more details about how you got it working? I mean, ideally, everything that you can think of ; for example, when you first stated how you got it working, you didn't mentionned where to put the .raw files for TESAnnwyn to find them, which turned out to be into the TESAnnwyn folder... same thing with TESVSnip : I was a bit confused at first about the way to import .ESPs into it, but I tried with ''Open'' and it turned out it was it. This could be of great help since those having the same problem as me can't really know if they made a mistake somewhere or if it's the instructions that aren't clear enough

.
Also, if anyone has any idea about what could be the origin of this bug, please, do tell! Thanks
