Chapter 15 Advanced Cameras and Rendering 633
The last part of setting up a node requires a little explanation. If you are unfortunate
enough to remember computers in the days of MS-DOS, you??™ll be familiar with running
programs through a command line. MS-DOS didn??™t have a lovely GUI with icons for
programs, so you had to type the name of the program to run it, along with any
???commands??? the program needed after its name.
Well, nostalgia is back! Despite the lovely Windows XP interface, some programs still
require you to run them through the command line, and LWSN.exe is one of them!
The LWSN.exe program needs to know a few things at runtime: where the config files are
stored, where the content directory is located, and which job and ack number it is going
to be in order to distinguish itself from the other render nodes.
Having to type all this information for each node every time you needed to run
ScreamerNet would be a pain. Fortunately,Windows enables you to create a text file that
acts as a stored command line. This text file has a special name??”a batch file. It has the .bat
file extension, but really it??™s just a plain text file.
