You probably used clipped_by or bounded_by- most likely the latter. Try one of those
instead of an iso keyword.

I'm still not sure why it was infinite though...

Perhaps you are confusing contained_by and clipped_by ?

Does clipped_by convert an infinite object to a finite one (internally,
I mean)?
The best thing to do is:
clipped_by { something } bounded_by { clipped_by }

It doesn't sound like it...bounded_by is the feature used to, well,
bound infinite objects, and based on the description it is the one he
wants.
The clipped_by feature is for removing parts of an object that are
outside another object, which doesn't seem to have anything to do with
this.
The contained_by keyword is only used in isosurfaces, to specify the
volume in which to test for the surface. It has never been used for
other objects (except maybe parametric), and wasn't even added until
after the isosurface patch had been around a while. (previous versions
reused bounded_by, which caused some problems)

As I remember, clipped_by (and contained_by, in the case of isosurfaces)
automatically set bounded_by. Wouldn't hurt to do it explicitly, though.

When bounded_by has smaller volume then probably not.

No, always. THe default bounding box will fit the default contained_by
object, not changing it when a bigger contained_by is used would be a
bug.

I was refered to clipped_be versus bounded_by from yours previous post. You
said: "clipped_by (...) automatically set bounded_by". There is known method to
put bounding sphere near camera for object far away camera. If such object have
clipped_by and this clipping object would set bounded_by automatically then it
sounds a little like a bug for me.

The situation is similar...not setting bounded_by would be a bug. POV
doesn't know about these tricks, to it, the bounding box is wrong
because some rays that hit the object won't hit the box. If it didn't
adjust it, it would cause problems in almost every scene, and the user
would have to manually bound it. However, it shouldn't override the
user-specified bounding shape, and I don't know if it does so.
Specifying bounded_by after contained_by or clipped_by should work
anyway.
