Hello there,

I am no Poser expert but I think the differences that ODF showed between the original object file and the file that Poser exports can be explained when you open both obj-files in a text editor.

V4:
Original:
v  0.00149163  0.65661299  0.00175520
re-exported:
v 0.00149163 0.656613 0.0017552
-> poser limits the second column to 6 digits

Antonia:
Original:
v 7.3631111e-3 0.65570511 2.3961111e-2
re-exported:
v 0.00736311 0.655705 0.0239611
(slightly changed a vertex)
-> poser limits the second column to 6 digits

V2:
If you throw a look in the V2-file you see this:
Original:
v -0.000692 0.644490 0.036993
re-exported:
v -0.000692 0.64449 0.036993
-> V2 only has 6 digits

I don't know if that is related to the slightly different deformations, but I think that it explains
at least the differences ODF spotted between orginal and re-exported file.
