The tent and such means a new map though, and that's additional work.
Thats true, i did not factor that. I guess i was married to the idea of not seeing her body or face at all until we give her the cash.
Perhaps we could skip the whole tent aspect and just have her sit next to the big tree at the entrance. At night she would move to an unused bench further into the park in order to sleep. Sex scenes could happen either right there on the grass or they could go into the bathroom. Perhaps Lisa could make disparaging comments about her in the morning, which could only be accessed by interacting with her while invisible.
I have nothing to replace the empty apartment, though. Iirc we never go inside Kaylee's apartment, perhaps the story could be morphed into those two living together as roommates and sharing rent n stuff. Or maybe Neala's apartment could be duplicated in the game files, that way theres no need to make a new map.
The way you phrased that leaves me wondering: Are you working on a new UD mod? I thought this was all a theoretical. Something like "this would never be done, but if it were, itd be like this". Would be cool if you are.
