I cannot seem to get the SL preview for mesh to work with an avatar body. In the uploader tool the preview is not moving even when I have all of the preview options selected and when my avatar is moving. What do I need to do to get the preview to match my in-world movements? Also it doesn't help that 99% of the time I enter the upload tool, second life crashes. EDIT: Now when I go to preview one .dae file and click "skin weights" under display options the uploader doesn't crash, but if I choose a different .dae file and click the same check box my viewer crashes. I am using the latest Second Life 2 viewer.
