So I started taking a look at 3d kasuko again after a few years, and starting thinking about if there is a way to edit a .tah/.tso file for mods that don't properly fit the NJXA body.
Long story short, I tried rebuilding a new .tah file after increasing the y axis on a mod that sat too low, and nothing happened in the end result. Is there someone with a bit more knowledge/experience in adjusting the mod files manually?
Also, I couldn't tell if this category was correct, or if JP would have been better. If not, my apologizes.
HONGFIRE had links to tools for adding/removing content from this hentai game, and of course you need to also have metasequoia installed. I remember loading the models directly into 3ds max, but this was a long time ago. Of course, bonnig and animation would be completely up to you.
