I tried out my baking skills on a loaf of brown bread. Want some?

I expect we shall have to extend the house to another room with the Xmas
dinner table ;-)
Looks tasty, Steve. Again, some darker brown to black around the top would
be good, and the coarse structure of the bread should be increased.

Thanks for the input. I hadn't thought of  using a gradient on the crust,
but that makes sense. I'm having a terrible time with the bread texture. The
more coarse I try to make it the less realistic it looks. I even tried using
a bump map from a photograph of a real slice of bread, and even that doesn't
look realistic. I'm beginning to think maybe I have to create several
hundred spheres of varying sizes and create a difference. Someone in the
newsgroup a while back mentioned a plugin called "dublicate", which could be
useful for this, but that thread has been erased from my news server, and I
can't find it in the web version either.

The "dublicate" thread came from me, incidentally. I attach it here again.
Remember that it will appear under the Tool menu and not with the othe
plugins!!
Otherwise, hmm... I have no ready solution for the bread structure. It seems
so simple (I was thinking also about bump maps or something) but it isn't.
Would an isosurface do the job I wonder? Alternatively, a heightfield from
the photograph?

Thank you. I've been trying heightfield, and it produces a perfect texture,
but when I try to combine it with the bread in a difference or intersection,
it won't render properly, and always eventually causes Moray to crash. I
havn't tried isosurface yet, it might work, but render times with
isosurfaces are sooooo slooooowww.

Concerning heightfields, you should not use intersection or differences
indeed. Best thing to do is to make the space outside the bread slice black
(height 0) and set the waterlevel at, say 0.1. That way, you only get the
slice rendered and the ouside part is ignored. Nice and effective! The
difficulty would be to position the heightfield perfectly with the bread of
course. For the slice it is less of a problem.

Er?  I've used heightfields with int/dif before and they work fine...

So I did, you just have to know that the height_field is infinitely extended
under surface, so to  intersect it with a box before  a difference could be
a good idea

Me, too, except that when combined with a mesh2 object it doesn't work right
for me (the heightfield is invisible). And if I play with it long enough, it
makes Moray crash.

We're on the same wavelength. I just got done making a heightfield as you
describe, and spent a lot of time getting it to fit exactly. There's
something Moray doesn't like about it. I saved my scene, and then worked on
the slices, and Moray crashed. When I opened the loaf scene again,
everything except the heightfield was gone, even the camera and lights. When
I opened the slice scene, the camera and lights were gone, and when I tried
to select something, Moray crashed. It's too bad, because it looked so good.
