А вот, кстати говоря интервью на эту b другие темы от Animal Logic - создателей softman (connector to Prman for SI3D) :

И выдержка для ленивых:
Q:Can you say if there will be a renderman tool for XSI in the likes of Mayaman?
A:Well, anything is possible. We are not currently in need of one for our own pipe. So there has not been a lot of effort in that direction, other than looking at the architecture to see what we would have to do. If you know anyone that needs an XSI translator to renderman, they can always contact us to see what we'd be prepared to do.
Так что все довольны менталом...
