Second Life Copybot

I've started to pick this up again after gicing up about a year ago...

So I know how to extract rigged mesh from SL into a dae

I then use blender to import this file and remove the demo signs from it. The object seems to be rotated by 90 degrees when I import it though. Is this a by product of MeshesSL? Also I'm having trouble exporting and keeping the weights on the original object. I'mn not sure if I need to rerig using Avastar.

Is there a how to somewhere on how to do this?

Thanks in advance

I would like to know as well  I also get an error message occasionally something about vml mesh and when i delete the xml and re-get it it gives me no errors wondering if it has something to do with lag in sl
