Just got back into playing around with OKW again, and I figured I might as well share some stuff I did.
First, some pube styles I made using Hairinator quite some time ago and never shared. Other than the first one below which I just made today for the hell of it. Each one is in an individual package file.
These pubes are available for females ranging from teen to elder.
Second, OKW has a ton of missing strings that just show as the string identifier, which anyone using it has probably noticed in the first few minutes of playing with it. I decided to look into adding in strings for those if possible, and found that many can indeed be fixed. I made a package including the ones I came across that could be done; it turns out that about... ~40% or so are apparently hardcoded and can't be replaced without updating OKW's dll file, which I'm not going to bother trying. The rest are properly run through Sims 3's localization methods and can be set. I created a mod package using the s3se tool which adds in all the missing strings which I noticed in a few hours of play and which were workable.
I'm not a writer, and I just added fairly simple text for what I thought made sense based on each situation and the identifier string given, and of course there are definitely a bunch more bits of text which I just didn't run into. The txt file included in this zip file has the strings I noted, both the ones that worked and are in the mod package and the ones which were hardcoded and can't currently be done. It also has a few other notes.
People are welcome to share either of these wherever they want, I don't mind.
EDIT: I felt like arrow-shaped pubes were missing, so I made some and updated the attached zip and thumbnails to include it.
EDIT 2: I've updated the Missing Strings package to include a few more missing strings, and to correct/update 3 existing strings. I'm calling this release v0.2; the text file included is updated to list the new strings added to v0.2.
This is probably the last release I'll make, though. I've started getting occasional crashes in my main savegame for whatever reason, and my interest in Sims 3 OKW is waning. Anyone else is free to improve on this and make their own releases with my blessing, if anyone else is actually interested.
