The new beta is just out of the door, featuring both voice and sculpted prims, the first cool thing is around.
The problem with sculpted prims right now was of course that no conversion script for the open source 3d program Blender was given from the start. But Second Life resident Amanda Levitsky just did it and created a tutorial on how to make sculpted prims with Blender. You can find it here.
I certainly looks like something for which you need a bit of understanding of Blender and UV textures and the like but from what I see there I guess the first steps are merely setup and then you can go from there and form your object. Of course one needs to learn about Blender which is surely more complex than the Second Life Building tools, but a lot of tutorials are around.
Great news and I love it when I see things like this happen where a resident just jumps in and creates the missing pieces. Another reason to opening up whatever platform is out there.
