That's window.oct with windows.rad added to it (the -i option).

Yes (same principle).

You shouldn't need to, rad does that.
I'm not sure if you can convince rad *not* to delete "il000949"
again after creating the final octree, because that's where you'd
find how it's done...  It should be a brightfunc referencing
illum.cal, but I don't have an example sitting around either.

The "il000949" (or whatever name it will get on the next run)
is the altered version of windows.rad.
