I usually define a variable at the top of my main scene files.
#declare SDL = true;

Then in any include file that I want to render when I'm working on them solo,
but just use as a plain include file when it's included, I do:

#ifdef (SDL)
     // do nothing
#else
     (all your global, camera, include, and other stuff you need to render the
file)
#end


and then at the end of the file I do the same check again


#ifdef (SDL)
     // do nothing
#else
     object {whatever}
     and any other stuff that needs to be rendered
#end



I'll also usually write a check for a variable named "Verbose"
which triggers macros and such to spill their guts to the debug stream
if it's false, then everything just runs silent.
