Radiosity

:o
Why did some objects disappear after I use radiosity in my scene?
I don’t understand it…
Thanks

They might be curves or nurbs of some sort?

With how many polygons are you trying to do radiosity? I’ve had this problem too once when I tried rad on to many polys.

I’m not using any nurbs or curves…
Maybe I’m using radiosity in too many polygons but I think the ones who disappear are the ones who are closer to the emitting meshes.
Ex: a bulb close to the wall make the wall disappear…
Is any way not to happen this? :-?
