Ok,
I think I am almost there with the skeleton, following your suggestions and Betty Doyle's link (thank you again).
I'd love to fix the skeleton only once as Kwakkelde Kwak wrote, still testing.
But.
There is another issue going on now.
This is what I see in Maya:
The pant fits the shape (the mesh is horrible I know, just for testing purposes), but when I upload it in SL it doesn't fit anymore:
I am wearing an incorrect alpha in height to show the big differences between the shape in Maya and the one in SL. And they are the *same* shape (I have downloaded the obj from Phoenix and imported in Maya directly).
This is not a matter of positioning but of difference of units, I guess.
Are there suggestions about the units to choose in order to make the shapes (and the mesh) match? Or maybe there is something wrong I am doing, or missing something?
I am exporting in fbx, scale factor set to Automatic;
when I import in SL, after the conversion fbx -> dae with the Autodesk FbxConverterUI, I don't set a scale - rezzed they are tiny but I don't care since I am not going to sell this things - and I simply wear it.
I hope that I have provided enough info for a clue, it's driving me crazy.
