Yep, I just realized it was actually there too, not blacked out and gone
entirely, just very dark.  I turned up the color of the light source to 10.
Something's wrong in the official versions though, I just couldn't say not
knowing anything about the source code workings.  Maybe Nathan has an idea.
At the beginning I simply thought the problem might be the layering over a
layered texture, which I expected would make an error show up.  Maybe that's
still something to do with it though.

| I had the same effect when I just used a simple checker :
| texture {
| pigment {
| checker color rgbt <0,0,1,0>, color rgbt <1,1,1,1>
| }
| }
|
| But filter works and I'm happy again :-)
