While loading up some older 3D stuff into RB 2006r3, it seems that the background property of the RB3Dspace no longer accepts Group3D. Looks like it only wants Object3Ds now.

I know this used to work in 5.5 and I haven't seen it in the bugbase, so I just wanted to confirm before reporting.

It's a reasonable feature request -- the change was intentional and
probably covered in the read-me or release notes when Element3D was
introduced, but now that you mention it, I can't think of any
particularly good reason for it.  Any Element3D ought to work as a
background; the only thing special about it is that it's submitted
before the shader (so it always gets null shading), and it moves with
the camera.

That suggests a probable work-around until this is fixed; add your
background group to the scene itself, but set NullShader on it (and its
contents), and manually move it with the camera.  Not ideal, but it'll
work.

HTH,
- Joe
