Unfortunately, we never aimed to deliver the same content for all available characters but instead explored various themes and settings for each of them. The only exception is the Supernatural pack, which exist for all bases. 🙂
As Kelemelan pointed out, making them interchangeable on the exports is pretty hard now, since the different characters have different poses, and in most cases, you just can’t just slap an item from a Female character on a Male one, as the perspective will be different. It could’ve been done easily on the 3D models when we created them, but back in the time, we didn’t recognize there’s a bigger demand for matching wardrobes, which came as feedback only later on.
We are looking for an option to try and fix this in the upcoming pack, to keep the balance of content between the packages, but yet again, it’s not always straightforward.
