[Sidefx-houdini-list] Multiple VRAYprocedural-files

VRAYprocedural is processed by CPP.

I'd create a site-wide file, say "MyPlugins.inc" which contained
something like:

--- CUT-HERE ------ CUT-HERE ------ CUT-HERE --- 
#define DRIVE /myDrive

#if defined(WIN32)

// Always include plug-in A.  If the caller hasn't specified a
// particular version, use the latest.
#define LATEST_A_VERSION 1.3.4
#if !defined(A_VERSION)

#if defined(A_VERSION)

#if defined(B_VERSION)
--- CUT-HERE ------ CUT-HERE ------ CUT-HERE --- 

Then, since you need control on a per-shot basis, I'd create a
VRAYprocedural file for each shot, with something like:

--- CUT-HERE ------ CUT-HERE ------ CUT-HERE --- 
#define A_VERSION 1.2.0
#define B_VERSION 1.5.3
#include "/myDrive/MyPlugins.inc"
--- CUT-HERE ------ CUT-HERE ------ CUT-HERE --- 

Of course, since the path is searched according to the HOUDINI_PATH,
you can have different VRAYprocedural files at each level.  So,
site-wide, you could have one set of procedurals, then override them
as needed on a per-show/per-shot basis.

That's how I'd do it, though I'm sure there are other approaches.
