If you're using radiosity, I think it was changed in 3.5b in such a way that it
would darken the scene, depending on settings.  That's the only thing I can
think of that would cause the difference.  Of course, I'm no expert.  I just
started playing with radiosity a few days ago.

See Malhalis's reply

Well, first, it wraps around the y-axis.  Which I assume you're trying to do,
since you're talking about the barrels.  Second, in order to get multiple
stripes, you need to use the frequency keyword with the number of boards in the
barrel as a parameter.  Then play with the settings until you get what you'd
like.

A real simple example (see attached image):
cylinder
{
    0, y * 5, 2.5

    pigment
    {
        radial
        color_map
        {
            [0.1 rgb 0.25] // Gray
            [0.1 rgb x] // Red
        }
        frequency 10
    }
}

plane { y, 0 pigment { checker rgb <0.5,0.5,0>, rgb <0.6,0.2,0.2> } }

camera { location <0,3,-10> look_at y * 2.5 }
light_source { <100,150,-200> rgb 1 }

To make the bands, I would scale the barrel slightly larger and cut slices out
with planes.  You can make the bands only as thick as the metal (instead of
going all the way through the barrel) by differencing the barrel out.

I like the composition.  The textures need some refining, I think.  The house
looks very rough.  The tiles need some separation from the grout, probably a
normal of some sort, at least.  And for some reason the birdbath reminds me of a
cocktail glass.

It shows lots of promise, though
