Sorry, I've already read your thread and it is an idea I considered at the moment for some of my dresses and bottoms, but then Dante released his jeans and I assumed the whole task was being taken care of, so I dropped the idea. Now, it's not only a matter of lack of time (I don't think I have actually used more than a dozen of my own mods, ever, and I haven't played the game for ages) and inspiration. I also don't have the modder program anymore (and don't want to get an "alternative" version so as to keep me away from temptation), so I'm afraid I won't be coming back soon (never say never though). You may want to ask Xteam, he seems very active lately, and he seems to know his stuff (he has a thread in the Loader subforum).
As for the "bug" you mentioned in the dress waist, once again, I don't even have the program to fix it, but I will say in my defense that I'm aware of it and it is not exactly a bug. As it's plain to see, most of my dresses are of the "copy/paste" kind (all of my mods had to be made within two months and I wanted to do a lot of things) so I needed parts as interchangeable as possible. the "low waist" of the skirt was made that way so that it could fit with the backless top part and it was supposed to be hidden by the rest of the top parts. The problem is that it is virtually impossible to take into account all the available positions (now they're making positions with separated legs, I didn't even know that was possible, and I know for sure that some of my dresses are going to look awful with those) so I had to reach a compromise and hope for the best.
Sorry again and thanks for your compliments.
