If the problem you're having isn't covered here, please check the tool-specific pages on this wiki and the mesh forum.

COLLADA file format

We support the COLLADA 1.4 specification.

Export triangles

We support triangles and polygons, not nurbs, surface patches, etc.

Skin weights

We support up to 4 influences per vertex.

Rigging

Your skeleton names and hierarchy must match the Second Life avatar skeleton.

Note: The following was pulled directly from the XML file mentioned in the above link. It includes an extra "head" bone (mSkull) which is, I believe, where the avatar's hair rest and the "skull" attachment point resides, and the mToeLeft and mToeRight bones, which are more than I expected to exist on the foot as I've been wanting a toe bone for years. I haven't tested if these are usable, animating bones yet. -Stickman 18:21, 20 June 2011 (PDT)
