Starcat Twine

So I've been tryign to grasp rigging in Maya. I had just finished getting weight painting done with my test model and went into SL to see how it would work. However I came across a problem once it's in the uploader itself. While in Maya I've got the model with Z-axis as up, and the object is facing via X.. in the uploader it's orientation is different. Also with Skin Weights enabled it makes it do this awful back bending. When worn the arms seem to move properly, but everything else is a mess. Any clue as to what I'm missing or doing wrong here? Help is greatly appreciated, I'm pulling my hair out here! Maya Screenshot - http://dl.dropbox.com/u/33583164/mayass.jpg SL Uploader Screenshot - http://dl.dropbox.com/u/33583164/uploaderss.jpg
