Yes. If LWSN is run from a directory other than where Layout is launched
from. Chances are you are having a problem because you have two machines
running ScreamerNet and they are not referencing the same content dir.
You'll have this problem if both machines are using the D:\ drive (for
instance) as their content dir. The scene is set up on one machine, but
the other machine can't see the objects on it's D: drive. One way around
this is to have a separate SN directory with it's own config file on each
machine that points to the proper drive (In one case it would be a shared
drive - Call it F:, and the other would be D:) Perhaps a better way is to
have one machine use a D: drive and the other use an F: drive as its
main. This way, you could mapa drive named F: to one machine (which is
the other's F: drive) this way if you save images to F: it will go to the
proper machine no matter which one is saving.. Also, you could have one
LW.cfg file for Screamernet which just points to F:.  I hope this makes
sense...

Not necessarilly, but the scene file loaded to render has to reference
the same Content dir that the SN nodes are pointed at.

Not at all.

 Nope SN will always pull the content dir from the config file it reads
from where it was launched (or at least where its "working directory" is)
