I Decided to try to do it because this seemed like s a pretty fun project. It took me a few days to disassemble the model into multiple objects, to fit it to HGEC body and then arrange the textures to make sure they are right. I also decided to remake the knee socks from scratch because the original one were hard to fit on the legs.
Now I managed to export it and have it in Nifskope but still not in the game. There's something I have overlooked that make it stretch forever even if it is weighted. I will continue to work more on it but as I predicted, exporting it would be the hardest part.
Here's how it look so far. After I manage to get it in game, I'll be able to fine tune it to remove every clipping issue. I might also have to remove the hood and make it a separated item.
So, yeah, This is what I'm working on right now. I also have Alice dress, which I will try to export later if or when this one works.
