Anybody used Motion Builder

We are ramping up to do a big project that requires some running characters in Maya. We used biped for something similar a couple of months ago and the art director was wondering if there was a similar product available for Maya. Motion builder is the nearest I can think of - has anybody used it ? What do you think ?

Thanks as always for your help.

do it again with biped,save them with pointcache and import them in maya.

Thanks for the help but…

Thanks for the advice but they are already rigged in maya - bringing them into max I think would be a complete nightmare. The other problem with these files is they have a massive amount of textures - upwards of 4 thousand of them each !! - we have reduced them to 50% and 25% just to get them to render in Maya on a 64Bit machine, doing that again for max I’m sure would drive me insane.

Thanks again - I guess I’ll be becoming a Maya animator again.
