Is that the one from Paul Debevec? If so, I've a setup of two lights
which fits close enough the default spherical mapping of this HDR into a
sphere, so the lighting and highlights seem to come effectively from the
HDR. It's what I used for the fruits bowl scene... it took me a while,
with lots of trial& error until I found the positions. Just ask for it...

There are tools around that do extract the approximate position of one,
two, three or even 20 or 100 light sources from any given HDR by using
a median cut algorithm. Have a look e.g. here:
http://gl.ict.usc.edu/Research/MedianCut/
and I think even PoseRay can do it.

Well when I tried to increase the number of noodles I got too many
escapees ... So I reworked BOTH the noodles and the canister. I don't
know if it's blender, or me (LOL ... willing to call it me for now) but
until I cleaned up the canister mesh (adequate number of verities for
collision testing) and redid the normals before I got it with NO
escapees ... noodle count up to 428 now.
As it stands the simulation took over an hour ... and hammered my poor
ole 32-bit dual core machine. I'm wondering if there's a way to decouple
the script editor ... maybe wishful thinking, but I've got a gut feeling
it's a significant resource hog.
Two more things ... I couldn't locate my kitchen hdr, so Jamie if you
don't mind, I'd like to try the one you mentioned. Oh and hey the
perfect noodle pigment is eluding me ... found some image's to sample
but not joy yet, so if anyone else can offer that magic pigment, I'd
sure appreciate the nudge.
Cheers

You can get the kitchen probe here:
http://www.pauldebevec.com/Probes/
Aren't you suppose to map it to a large sphere?
What are your macaroni, texture settings? They could definitely be a bit
more yellow or is your glass absorbing the colour?
What does the pasta look like out of the jar?

It needs for sure some colouring, now it looks like a cannister of maggots

Me too... I didn't talk with Koppi yet about it, but I think it would
be a good idea to test if removing the editor improves speed. If so, an
option to disable, or at least "freeze", the editor during simulation
would be very helpful for complex scripts.

You have it into your mailbox already... and as Ive pointed out,
Poseray can extract lights from an HDRI. I never tried it for that, and
should do some day.

I have a problem with the kitchen probe: no mather what projection I
use, or what convertion I do, there is always an ugly glitch that cause
extreme stretching along the seam.
I convert from the spherical image to the longitude-latitude format in
HDRShop and apply to a sphere or sky_sphere using a spherical mapping.
Same thing if I use the cross format as a source.
Also, it's a single view point probe (you see the camera) while beter
ones use a 2 view point setting.

LOL ... funny but not helpful ;-)
How's this ...
I think I've settled on this "kitchen counter" pose. I had to redo the
noodle simulation, I noticed some intersections. I just gave the even
numbered noodles a slightly less "mass" value. The utensils/rack are a
model I found ... it needed some work, but wouldn't import into blender,
but would in poseray. I'm going to keep the utensils and make my own rack.
I think I'm close to over doing the angular look I have going on ... so
to break that up, I'm working on a pepper-mill for the foreground (left)
tipped on it's side (into the scene) with some peppercorns scattered on
the counter.

Much better... the tiling work is very nice, BTW.

Curiously, I've been thinking on making a simulation of my cutlery set
falling vertically into a rack, to obtain a rack full of realistically
placed flatware.

Nice touch... but don't forget to put a cheese piece somewhere. :)
