Re: XSI/FXTree livefeed of renderpass?

["Tim Leydecker" <BauerOink(at)gmx.de>]

Hi Adam,

thanks for the info and query. What I hope to achieve is
to pipe a *not yet rendered/updating renderview* into
an otherwise static FX Tree composition.

Like putting a viewer (displaying the last renderregion or
renderpassrender on the correct frame) in the middle of
a comp and using that to influence the final comp.

If I´d have to refresh a couple of times by manually re-
rendering a pass (e.g sequence of frames, like a turntable),
reloading a pass and re-chaching the result in FXTree I´d
not gain much really over a solution using XSIpass(es)>AE
or XSIpass(es)Combustion and doing the comp there.

Additionally, I´d not require Adv/Ess but could do (later)
with a Foundation license...

Cheers

tim
