I thought it would be fun to see if I could get this little fellow to
look like my favorite treat. I think I'm headed in the right direction,
although I had a time finding an ior value for chocolate. The best I
could come up with was a discussion that offered a guess of low 2's (I
chose 2.2) ... the specular is not very saturated but the roughness has
a fair amount of bloom ... with a bit more lighting work I think it will
look fine.
I've also been working on a crinkled foil texture to wrap around an ovus
or two ... after all whats a chocolate bunny without a few chocolate
eggs to keep him company ... right!

@Trevor: It /would/ be nice on a bronze bunny though :)
@Jim: Looking yummy; have you considered an Easter basket/grass for the shot
too?

It's not as pronounced when I disable sslt, and the other finish
attributes are pretty sparse, so I'm suspecting that lighting and or
viewing angle might need some minor adjustments ... the role of diffuse
seems a bit different with/without sslt as well.

ha-ha ... it does resemble a bit of corrosion now that you mention it

Given the timing (purely a coincidence btw) I could see how that might
be one option, but I think I'll opt for a less secular approach ... I
mean I get the symbolism of new, rebirth, eggs, chicks and bunnies ...
how the heck did chocolate worm it's way into the holiday. Bigger
business in chocolate -vs- eggs I suppose ... bloody capitalists ;-)

For anything organic, something around 1.3 (water) is a good first guess.

For chocolate, I'd look at the ior of water (1.3), some oils and organic
greases like butter and shortnings, obviously NON-melted.

While waiting for a render to complete I did some more digging and found
a list and thought I'd pass it on:

Looking at that, I think that a value around 1.37~1.44 sould be
reasonable for chocolate.
