[Bf-funboard] some pipeline related requests

[Campbell Barton]

Quick reply, I think Bassam covered this mostly, but here goes...

1 & 1.a: Use Python, I know this may sound like some cop-out answer,
but if you really want fine grained control about rendering different
layers to different locations... you can get this with quite a simple
script, Also these kinds of issues tend to be less obvious & generic
then you might initially think (how to handle animations, overwriting
options, color management.... ) its all possible, but with Python you
can fine tune this stuff, probably the script will be <25 lines and
not hard to write.

I would go as far as to say - if you want to have configurable render
farm, its mandatory to have some kind of Python initialization script,
which handles any number of details - check for missing textures,
baked caches... check output paths on compositor nodes etc...


2. Yes, see "Environment Variables:" section in "blender --help"
