About This File
This is an edited version of the YgNord skeleton that comes with the ECE package, modified to fit the x117 clothing. It's shorter than YgNord, being about as tall as the children in Skyrim. It's female-only... sorry about that. I also packaged the body and textures from Children of the Sky with it. Basically, you get a Sky Child that can use ECE, but you'll be the only one in all of Skyrim.
This does not play well with the Children of the Sky mod, but the ECE works fine. I have no idea if it works with xvisionchildren, since I can't find a copy to download anywhere except the one contained in and merged with CotS.
The skeleton isn't fully set up for dual weapon sheaths or staves on the back or anything like that. I kinda gave up halfway through setting that up. Also, it doesn't have the tail bones, wing bones, cloak bones, or hair bones that the CotS skeleton has, so if you have costumes that use those pieces I have no idea what'll happen.
What I did to make the skeleton work is add a scaling node before each normal node, and then I moved all the scaling to the scaling nodes so that every normal node has scale 1.0000. Since ECE requires a skeleton with bones scaled to 1.0000, it works even though the skeleton is actually scaled differently. It also means that if someone wanted to, they could make something like ECE-CME to alter only the scaling nodes, and morph shape on the fly.
If someone got the scales for all the different bodies, and added the bones that this skeleton is missing, then you could have a body that could be adjusted to fit all the current skeletons. Of course, it would have double the normal number of nodes due to the scaling nodes, but there isn't any reason if shouldn't work. That being said, I'm not ever going to make such a thing. I lack the programming knowledge to do it.
Anyhow, so this works fine and is easier to install than CotS if you just want to play a Sky Child and don't mind all the other children looking dumpy and boring and stuff. If you use it, don't forget to get some x117 clothing to wear!
