Quote - Will the update overwrite anything? I have unfinished projects using her, so I wouldn't want to load the scenes and be surprised by unforeseen changes to old files.

it overwrites everything.

new textures will give her a new skintone regardless of whether or not you load the new skin shaders, but this isnt a problem unless youre in the middle of doing something like a comic book and dont want her skintone to change halfway through :)

there will be a second INJ that injects new morphs, and a separate folder with the new shaders so that people with <Poser 9 or DS can continue using her as before.
