No no, not the major !
At least i don't think so...

In Innocence i'm sure that the sets have been made using LightWave and i think that some of them as well as SFX in the first movie.
And there's a lot of movies in Japan that have been using LightWave for the sets, before XSI came up for some of them.
Dstorm for example is a LightWave house (they are even LightWave reseller in Japan...) and their studios are doing a lot of things for feature films in Japan.
