I think manta is an internal project , created by the special project group .they've done it to debug the software with something that is close to a real production , I guess , and to deliver consistant demos .
Perhaps they don't have time today to finish the film.
why do you think they are hiding it in some ways ?
I saw a few finished shots (the landing of the ship in the snow is really nice)
some people like manta other hates her.
(I love the face close ups but not her body)
I think it's a great thing that people at softimage are testing the software in a production like env.
look at all the good stuffs coming from Olivier Ozoux or Michael Isner.
the special project group are moving to companies to help them start on challenging projects and it's a good thing.
I understand.
