Renderman for Maya motion vector

What's the best way to output a motion vector pass out of Renderman these days? With all the latest changes motion blur isn't quite as cheap as it was so am considering doing it in 2d, would be nice to hear opinions how to get a good pass out as I can't see a straight forward option right now that works. :/

Cheers!

Anything preventing you from adding an AOV to output dpdtime?

See this thread http://www.3delight.com/en/modules/...topic.php?id=61 it's for 3delight, but it easily works with renderman for Maya.

Thanks for the replies, I'll dig into that thread over at 3delight shortly.

Regarding the dPd pass, I'm using the latest Renderman and it doesn't seem to output something I can use right away. I might have done something wrong though - it only outputs in the green channel and at some parts where there is motion in the rgba the dPd outputs straight black... >_<
