We??™ve learned so far that for the master computer to
???talk??? to the nodes, they all must be able to see the command folder because they use this
to pass messages to each other. The nodes must also be able to see the content folder
because it stores all the files needed for rendering. Thus, the content folder holds the files
for rendering, while the command folder stores the instructions on what to render.
Configuration Files
In addition to the content and command folders, a third item must also be accessible to
the nodes: plug-ins.Any plug-ins you??™ve used to create effects in your scene must also be
available on the network. For example, if you??™ve used Sasquatch to create hair on a character
or a motion plug-in to move an object (LightWave itself uses plug-ins to load and
save files), or even if you haven??™t used any FX plug-ins, ScreamerNet still needs to know
where they are to save files after it has rendered them. All these plug-ins are separate files
that need to be loaded by the LWSN program, just as LightWave did when you created
your scene.
When you think about it, if the ScreamerNet program needed to know the location of all
the plug-ins you have installed, you would need to type the location of every single one!
That would be a lot of typing! The way LightWave deals with this is by storing the location
of all the plug-ins in a configuration file.
