Hm, I'm having issues with Oscape now, primarily with the generation of the .raw heightfield. Just realised you need a .esm file to work with Oscape, you should probably add that to the tutorial since I had a .esp I've been trying to create a .raw for and Oscape just throws up errors. I ended up using wryebash to create a copy as .esm. Also once you've used the .esm in Oscape is it then fine to use the .esp it was copied from in the CK? Obviously I can't set an ESM to active file is all. Also should I load up Skyrim.esm in the CK as well or just my own mod?
May be this is the reason why it don't work? This is the preview of my map but I see in the explanation page that shoudl look much different ... any ideas? http://img825.imageshack.us/img825/1092/62455137.jpg
..I'm getting a similar issue to this. The big black squares aren't as big as that but the image does look overly blocky, I'm sure I've had it come up looking more like your original screenshot of the process before. No idea if this is an issue or not mind. Oscape seemed to do the rest of the process without errors thus far.
- Copy all the LOD .btr files to the common\skyrim\Data\meshes\Terrain\yourworldspace folder.
Could you clarify this bit please? Do you mean preserve the file structure (IE keep all the folders "LOD-500000", "LOD-125000" etc? Or just take all the .btr files out of there and simply dump them together within the one folder? EDIT - It appears you dump them all in the root folder, this got some form of LOD working for me, although it doesn't seem to be working ideally and there's some serious issues round the edge of the map, especially this giant 'wall' where I'm assuming I got sea level wrong or something..arrgh..
- Make a border region in the Region Editor. it doesn't need to contain anything, it just needs to outline the total area where you will want LOD generated in. And make sure the "border region" box is checked before you apply.
- Go to Worlds -> Generate Max Height Data For World (NOTE: This assumes you read the pervious step and have created your border region) Hit yes, then no.
- It'll take a bit to load, but when it's finished, a box will come up that says "done"
I wasn't too sure what you meant by the region editor, although a bit of confusion later seemed to work out how to create a border region. After this however when I went to generate max height data for my worldspace I get the following error -
DEFAULT: Failed to calculate Max Height data for cell (x, x). Maximum low res value of 260094 will not fit in byte storage at Z granule of 256.If anyone has any idea what this means I'd be much obliged. This error occurs for every single cell as far as I'm aware and despite the 'yes to all' button it just repeats it for ever. Clicking 'no' exits the program. It also says the following beforehand, which seems a bit off -
Generate max heights for cells (-74, -74) to (73,73) [21904 cells] in border region of world 'myworldspace'?It's the -74, -74 there that confuses me.. my worldspace is 64x64 cells and the border region is drawn within those confines. Why does it think my worldspace is 10 cells wider than it is? Could this be the source of the error and if so is this related to the region editor?
For now I attempted just to skip this part entirely - what is it's purpose? I already have an .LOD file for my worldspace and a working .esp which is playable in game, albeit without LOD working. The next step seems to be chugging away nicely, albeit I'm a bit pissed it decided "switching to single threaded mode as only generating textures" - oh ta, CK, thanks for only using one of my 8 cores, I'll see you in 4 years time

I'm in actual genuine hell here trying to get this working, even after following several tutorials to the letter. Based on the .pngs generated by Oscape I'm really hoping that a lot of brown solid colours and a lot of purple stuff is what I'm supposed to have got out of it.
I don't understand how other people are doing it, it's been doing my [censored] in for the past week. Do I have to go through the entire process again every single time I make changes to my worldspace or terrain mesh/floor textures/objects etc? If anyone's feeling charitable here's my worldspace - generated originally using TESannwyn - it's of Vvardenfel and Solstheim so I'm sure a fully-working version of it would be useful to some modders at least.
