Hmm -
Ok, I'm not having an issue finding dependencies (this does the job just
fine, for example:
http://community.thefoundry.co.uk/discussion/post.aspx?f=190&t=103381&p=894390
), but I discovered that I don't have a way to find my *currently
needed* dependencies.
Basically, let's say I have a write node and want to find nodes of a
certain class in it's dependencies, let's call the class 'PreRender'
I want to render those prerenders, but only those in the tree that are
switched on.
I have a switch for prerender1 and prerender2, because the tree above
them branches with some differences specific to the prerender. I need to
render two jobs at two separate times, manually switching them, but the
output is to the same write node. The pipeline fills in the write path
based on 'stuff', so I'm not actually overwriting anything when I
re-render - except that, even though prerender2 isn't being seen in the
first render because the switch is looking at prerender1, it's still
part of the dependencies tree, and consequently, it's getting rendered.
Is there a way for me to walk through the dependencies via python to
eliminate the non-rendered part of the dependencies tree?
thanks
