Ive been playing with SimOnAStick and makehuman for a bit and i have made a bit of a discovery.
Currently the Dae export does work to get the mesh compatible with SecondLife but it is of course a Static Mesh (not rigged). So it does look like maybe the work in doing SL format is a bit farther along than the to-do list shows.
On a similar subject does anybody have a copy of the Avatar WorkShop rigged mesh handy?? (the original site seems to be facedown in the gutter)
