Question About Mesh Avatars

I'm am really clueless about mesh avatars. Is it possible to buy and use avatars from a site like this? What would the requirements for opensim be in order to have these work?

I'm asking because I want to use one of them for a video I'd like to make. Thanks in advance to anyone who can help answer my questions or point me to an article.

Hello Koshari,
I'm afraid this gonna be a rather disappointing answer for you. Most of those sites forbid the importation to at least second life I do not know if this includes OpenSim also. But I wouldn't be wondered at all. Of course I do know that it's regularly done. Secondly you'll have a mesh avatar but to be working in any grid it has to be rigged to the bones of virtual worlds and you can bet on it that this is not done.
Sorry

If licensing is OK for importing to an OS grid (SL usually excluded, because of its TOS), the model has to be, usually, retopologized to make it suitable for skinning and vertex weighting. In English: remodeled so that it has evenly distributed vertices arranged in evenly spaced loops. Then it has to be 'skinned' AKA parented, or attached to the OS avatar armature, and vertex weights painted so that the body moves reasonably accurately with the armature. If the armature needs to be modified - for an unusual mesh body shape that's too far from the default avatar shape - then you'll also need custom animations. You'll also need to take into consideration UV mapping (how a texture is mapped to the mesh) and materials - you get up to 8 faces per mesh object inworld.
All doable, but it's a fair amount of work.

Thank you Zed and Ada,

That sounds like a whole lot of work and its way over my head. Thanks for taking the time to explain it to me. I think I'll have to forget this idea, too bad though because I really wanted to make a video with one of them.

Forgot that you might run into the retopology too depending the model as Ada rightfully mentioned. Just for whomever might be interested after. There's a neath free program to model a character.

I do not say it's perfect and above mentioned rules still will apply, at least the last time I looked at it. Since it's open source I've got no idea what they been adding. Making avi's/characters is really not my speciality. Say already years I should have a decent look to it but there is always something else to do.
