Did people give up on this? If so, that's a crying shame.
I get that the meshes available are not the best for a texture nude mod, but maybe the Angel of Darkness Classic skin would be easier to texture mod? Take a look at the attachments.
Having a nude mod for that outfit would still be pretty rad.
Also, succesfully modding this game would probably set a good precedent for the next Tomb Raider game, rumored to be called Shadow of the Tomb Raider which would be very likely to use the same engine which means the same tools perhaps be used to mod that game too in the future. Most likely, but who knows.
