I've had a quick look at a simple cr2 file dating from 2010 and couldn't find anything relating to IDL or light-emitting.

However, I turned off 'light emitter' and saved a copy back to the library. Original file = 24kb, copy file = 32.4kb, so there's a lot more info saved with the copy. Here's one of the key bits:

 

Original:

endPoint 0 0.12714 0.399425
origin 0 0.22714 0.399425
orientation 0 0 0
displayOrigin 0
displayMode USEPARENT
customMaterial 0
locked 0
backfaceCull 0
visibleInReflections 1
visibleInRender 1
displacementBounds 0
shadingRate 0.2
smoothPolys 1

 

Copy (with light emitting turned off):

endPoint 0 0.12714 0.399425
origin 0 0.22714 0.399425
orientation 0 0 0
displayOrigin 0
displayMode USEPARENT
customMaterial 0
locked 0
backfaceCull 0
visibleInReflections 1
visibleInRender 1
visibleInCamera 1
visibleInIDL 0
displacementBounds 0
shadingRate 0.2
smoothPolys 1

 

I've put the relevant property in bold. 

So the question is, does Poser add the extra properties when it loads or only when you save it? I suspect it's the former, which is good news from the point of view of writing a simple python script to turn the 'light emitter" property off.

My python skills are next to zero so I won't have anything any time soon: perhaps someone to whom this would be second nature could have a go?
