I came across an article on a new way of building 3D virtual worlds. (Thanks Hamlet NWN) Well, may be not so new, it came out in 2011 I think. But, the process, new to me, is being used to create the independent adventure game: Rustclad. The development team has a video out showing the process they are using and early scenes from their game.

You can see they are using a more organic style than we typically see in Second Life™. Sculpties were introduced to Second Life to enable the creation of this more organic style. I am not sure we have ever taken advantage of sculpties as intended by the creator of them: Karl Stiefvater (Qarl Fizz, formerly Qarl Linden). May be I’ll ask him some day.
