Hi,
are the DAZ figures (core .OBJ) symmetrical? If not, where is symmetry violated?
Anybody knows?
Best,

No V4 isn't exactly symmetrical.  The best way to discover where it is off is to load V4/M4 and look at the size and the location of each individual body part.  It's not a lot, but you'll see it if you are using a 50x or 100x magnification.

Modo has a symmetry checker/fixer tool which hilights the exact verts which aren't symmetrical.

According to Modo the V4 base mesh is perfectly symmetrical if you open the source obj directly in modo without involving poser. Once V4 has been loaded in poser, zeroed and exported she is way off, only her midriff and face/scalp are still symmetrical.

M4's base obj isn't quite perfect, one iris is off and about 100 other verts sprinkled all over him are very slightly off (a 'fix' threshold of 5 micrometres is all that's needed to fix them). Once he is exported from Poser his entire mesh is completely off so I'm guessing his center must have moved during the loading/exporting process.

Ah. But the topology is the same on both sides, just the absolute positions a bit off?
The figures have I think a problem in the hip joint, which I think rotates the figure a bit.
Once its loaded in Poser, its off, thats clear.

Yes, according to modo there's no difference in the topology, it's just the positions that are a bit off. Once modo has shifted the stray verts a microscopic amount it regards the 2 halves as identical.

I believe the V4 mesh was created in modo (probably others too) so I assume they made use of modo's symmetry tools. Asymmetrical topology  would have made that impossible.

Thanks for the info obm890. I have often wondered if Poser introduced asymmetry when exporting obj files.

For Poser exported obj files:

I IRC,  Poser OBJ exporter has serious problem in precision of floating point caluculation.
Load simple cube prop from standard Poser library and export it. It's a 5 x 5 x 5 verts cube.
All corner verticies locate exact coordination such as (0.1, 0.1 0).
But second row vertices are (0.08, 0.1, 0) , (0.07999999,0.1,0), (0.08,0.1.0), (0.0799999,0.1,0)..

I'm not sure but if the problem is precision, you can revert symmetry by round off all V line
at 6th or 7th decimal place. I once did that to fine adjust morphed A3 character in Modo.

But it's a old memory, in Poser-6, Modo201 days. Maybe things are changed now.

About original Obj file in geometry folder,  DAZ-A3 is perfectly symmetrical in modo.

last i recall, DAZ base figures were made in Lightwave.

If you elect to export Mil4 figures (V4, K4) as a morph target, symmetry is pretty much spot on, at least when using Hexagon.

If you don't export as a morph target, no, there are asymmetric vertices all over the place. But then you don't get any of your dialed morphs when you export the figure as a MT.

Can Modo make the .OBJ perfectly symmetrical without changing the geometry? I.e. move the verts that are a little off to their symmetrical exact place?

If so, one could use this to derive a symmetry map out of a perfectly symmetrical .OBJ easily and adopt morphs to this.
