maybe try a ray switch material with it (slicer in direct visible slot),
this probably should get the light untouched (in most cases at least, not if you cut away a part with a window opening)
other than that, as option, keep 2 copied one cut one uncut and use the corona compositing tag
You can indeed use the rayswitcher if you want to cut something away but leave the interior lit as if it was not cut away (e.g. remove the roof from a building, but see the rooms lit as if the roof was still there). Slicer into direct visibility, nothing into the GI, and that should be it if I remember rightly.
I will try these and let you know. Thank you very much.
I think Slicer works correctly. It would be odd to see the shadows from object you don't actually see...fe.: lamps, ceiling etc.
And the rooms probably will be whole dark.
If you take real object and cut it you will not see shadows from the parts taken off.
Beside, IMHO, the Slicer doesn't slice shadows, you just see shadows of the sliced objects.
Yes, it is working correctly. It doesn't matter if it is physically correct. The point is to generate presentation images, not a realistic renders. The rooms will have their own lights etc.
Vray already has this option.
