Anim8or Community

I'm not sure if the vertex indices will always remain the same when exporting and importing between different programs. Even if it did, there is no way to preserve the skinned mesh information in Anim8or anyway. Anim8or treats it as if you added an entirely new mesh, and so you must re-skin it.

A feature request could be to enable export/import of vertex weights, or just a more in-depth UV tool.

[Edit] Assuming I'm right about the above statements, there is a trick you can do. Import the newly unwrapped model into a new file, save it, and then open both files in notepad. Copy the mesh block of the new model into the old one, replacing the old mesh's block of data. This will only work if the vertex indices were preserved when exporting/importing.

Make sure it hasn't been modified as per 'Kreator' post.

Don't alter the models XYZ location or size from this point and backup your file.
- Export your model as an obj. file.
- Import it into your favorite UV mapper. Re-map it, texture it, whatever.
- Export from the UV mapper as obj. file.
- Import it back into Animator and copy and paste it to the location of the original model.
- Delete the original and the newly mapped model should be working fine in the sequence editor.

Generally vertex normals are used to indicate lighting, yes. Rest assured, flipping normals is the same as flipping a face.

For the toon outline effect you can flip the normals of the outer mesh or just create a 2-sided material for the outer mesh and have the front material transparent.
