According to the help text in the girl editor the names of the files have to be in specific formats. Some of the naming conventions you use are in violation of said formats. I am sure they still work and imagine this is due to a game change somewhere but just wanted to be sure.
They are supposed to be Sex1.jpg, Sex2.jpg, etc. but actually Sex1 (2).jpg or Sex.jpg or even Sexton.jpg work just as well. However the Preg files are different. Preg1 (2).jpg won't work properly.
Also what do I do with the files in the preg packs? Put them in the individual folders I would imagine unless there is a script somewhere that can find them. I think they would need to be renamed as well but just need some clarification.
Yeah, they need to be spread out among the individual folders. I don't know about renaming - what sort of filenames are there? There is some special handling for Preg files so you can have PregSex1.jpg or PregBDSM1.jpg, etc.
