Hi,
Maybe related to Tommy's phong problem.
since the textfieldbranch still has the old cube I downed the
latest fllash 9 build from the site to increase segments of the cube;
I did this because the phong looked sucky wit the 2 big triangles
on the front.
when I applied phong I get also weird results.
After some testing it turned out that when I zeroo'ed all light
coordinates to zero, the phong material looked better.
But still when zeroed,the light looks like the specular shininess
is lost (on the cube.
Here a demo which decreases light.x till zero.
Watch the weird phong go better in 100 frames.

Hey Tommy
sorry for the problem you've encountered with the update - the
solution is not obvious from here, so can you let us know a
little more about how you are rendering the object?
are there multiple materials on the object?
are you using ownCanvas at all?
are you using pushfront or pushback on the mesh?
ultimately the best way to solve this would be to send a copy of
your model over for us to test independently. However, if this is
not possible, you could try replicating the bug with a different
model and send it over as a test case so that we can debug
cheers!
