An Overdue (Non?) Progress Report
I'm still alive (mostly) and still plan on fixing this mod (and making it fully open source). The sad truth is my workload has increased rather than the expected decrease and I haven't had time to work on it at all. (I haven't even had time to just play the game!)
Overall
Presently to get the mod to work (and partially at that), you need to:
1. Install the last version of the mod from the ZTS era. (Choose only texture stuff, breast jiggle/sizing and other tricks extremely broken)
2. Find the post I did that included the modded & compiled bins, you'll need to manually place them
3. Sacrifice a tribble
There are still around 100 costume mod files that do not patch properly and until I finish my research (see Research below) I won't be able to fix them.
I may try to squeeze in at least doing a fresh compile (I understand the game did some updates lately) and have a post with the last installer and the stuff to patch the mod with some (hopefully) simple instructions so things can at least continue to limp along while I try to escape the event horizon of too many projects.
(If someone else wants to make a post with all the needed stuff attached to one post before I get to it, you have my blessing and thanks.)
Texture Seams
The seams have always been an issue and may not be solvable (at least not easily).
Research
I still need to really understand *how* the mod actually works (why does X need to change to Y in the game's resource files). I have the old documentation on this but I haven't had much time to do more than skim it.
Using The Mod
This is a client side mod that does not do any gameplay changes so should not be violating terms of service.
You should always disable it when streaming or capturing play so people don't freak out because of nudity and jump to weird conclusions.
