I am currently working on transferring Poser models to Blender with as little effort as possible. For this purpose I'm using parts of "PoMo" (FullbodyMorphs_wx4.py) from the beginning of the year, besides some other scripts. Again I stumbled over the problem with the unused vertices that Poser does not remove from the "UniMesh".

Old thread: https://www.renderosity.com/rr/mod/forumpro/?thread_id=2941172

Now I was forced to take care of the problem and came up with the following, really simple solution:

    def used_list(_geom):
        """
        Return a list with 1 at positions of used vertices
        and 0 at unused vertices.
        """
        sets = _geom.Sets()
        ar = np.zeros(_geom.NumVertices(), np.int8)
        for poly in _geom.Polygons():
            start = poly.Start()
            numv = poly.NumVertices()
            for _idx in sets[start:start + numv]:
                ar[_idx] = 1
        return ar

The returned list is then used in the following function, which creates a crosslist:

    def crosslist(_used, _verts):
        cl = np.zeros(len(_verts), np.int32)
        not_empty_idx = 0
        for _idx in range(len(_verts)):
            if _used[_idx] != 0:
                cl[_idx] = not_empty_idx
                not_empty_idx += 1
        return cl

And the problem is solved. Quick and simple.

The new crosslist is used in the above mentioned script just like the previously created crosslist. But I don't save it anymore, I create it every time anew. The recalculation costs almost not noticeably more time.

Explanation:

Function used_list() creates an array of the length of the vertices in the geometry, initialized with zeros. Then the polygons returned by Poser in UniMesh are scanned and the array is set to 1 where a polygon actually uses a vertex. Not used indices are later skipped (vertices not written).

Function crosslist() now uses this list instead of checking vertices for [0.0, 0.0, 0.0]. This caused problems if a polygon actually used [0.0, 0.0, 0.0].

The core of an export function then looks like this:

        # exporting vertices
        used = used_list(vertices)
        for idx, vertex in enumerate(vertices):
            if used[idx] != 0:
                print("v {} {} {}".format(*vertex), file=fh)

The "sets" must be rewritten like this:

        vertex_crosslist = crosslist(used, vertices)
        sets = geom.Sets()
        for idx in range(len(sets)):
            sets[idx] = vertex_crosslist[sets[idx]]

A complete script based on "Script Buttons" can be downloaded from:

https://adp.spdns.org/#ObjImExport

Script Buttons: https://www.renderosity.com/rr/mod/forumpro?thread_id=2954892

I've been having an issue with the import figure button in Poser 12. It keeps erroring out when it tries to load the vertex data.

As far as I can see, it seems like something is wrong with your file written from you modeller.

Can you import this file directly into Poser (with the "Import OBJ" function)?

For speed reasons the import function in the script does not check for problems or error conditions if only the file exists.

Script should run fine with P11 and P12. I didn't test P12, but an adapted form of the script in question (im_export.py) runs natively with Python 3.9.

Thank you for the response, i checked the files and the vertex numbers add up and everything but i think it might be my poser install. Reinstalling and checking, if it doesn't make a difference i'll try in P11.

Updated.

Now able to deal with more then one figure in the scene. Each figure will have a seperate entry in the config file for pathes and filenames.

TYVM :)

Forgotten to mention: If you used it before better delete the config file ("imex.config", same folder where your script is stored).

If you want to join several morphs into one full body morph, do the following:

1. Dial in all morphs you need to shape your character.
2. Uncheck "Silent Im-/Export".
3. Export to "Figure_Morphed.obj".

Don't move your figure from now on!

1. Set all morphs you want to combine (and later delete) to zero (don't use dials, insert a "0" to be sure it is really 0).
2. Export as "Figure_Unmorphed.obj".
3. Set a Morphname for the final morph.
4. Import "Figure_Morphed.obj".

You may now delete all the morphs you have set to zero before.

Update

Click to download

Supports Images, Bump and Transpareny for import into Blender better (mtl file).

Switch "Copy Imagefiles" on and off, because it makes no sense to copy the same images again and again to the same folder.

That sounds great. I'll definitely try that out and study the code.

New version with some updates.

Most widgets are now "ownerdrawn". Should run with Poser 11 and 12. Don't know how it works with iOS.

The morphname field can now automaticly increment (Checkbox autoincrement). If auto increment is enabled, two digits separated by a dot are appended to the name (if they are not already there). The number is incremented with each export.

If "Export Groups" is enabled, Blender, for example, can automatically make vertex groups out of them.

"Do not always leave "X Center == 0" switched on. It makes sense if, for example, the center vertices of a head were moved during morphing (they are at X position 0). This happens easily when working with the Soft-Brush. I often use the soft brush on one half of the head (or chest) and then let Poser calculate the other half of the face/chest with the morph tool. This solves the problem of not being able to work symetrically with posed figures in Blender (and other modelers).

"Auto Sync" makes sure the figure in the script is always the one you have selected in Poser. Attention: Each figure has it's own morphname. If you change the figure, the morphname is also changed (switched to what you used before).

How to install:

The script consists of a main script ("Run.py") and a folder containing the required script parts to be loaded ("local_libs"). Create a separate folder for the script.Mine is called: "IM-EXporter". Unpack the ZIP file into this folder. From Poser you can then:

1. start the script "Run.py" via Posers filemenu "File->Run Python Script...", or
2. add "Run.py" to the file "/Runtime/Python/poserScripts/mainButtons.py" and add the Poser Python script buttons (my preferred method).

Path structure:

IM-EXporter
....local_libs
........__init__.py
........im_export.py
........wxPrepare.py
........WXTools.py
....Run.py

im_export.py contains anything to export a model and import a morph. The script strictly separates between UI part and the part that does the actual work. The result is that the import and export functions can be executed stand alone without any restrictions. And so of course can be used in your own script via "include".

wxPrePare.py contains functions that allows the script to work with both wxPython from Poser11 and Poser12 (i.e. Python 2 and Python 3).

WXTools.py contains wxPython functions and recreations of some standard controls ("ownerdrawn").

Thanks! I was going to ask about that, not having done anything with Poser Python for a decade. Also this looks like a nice demo on how to load local libs in scripts. If I don't get too distracted by other things, I'll give this a try tomorrow.

Hey adp001, is it possible that you packaged an outdated Run.py with the latest version? It's trying to read the IsChecked property of a CheckboxCtrl, which only has IsSelected. Also it seems to register native checkbox callbacks that CheckboxCtril does not have. I have less than zero knowledge of wx, though, so I may be completely misunderstanding something.

I managed to get the script to export a mesh with a morph on it, but none of the various option buttons seemed to do anything.

Ah, never mind, I wasn't seeing the complete interface. Looks like it's all working after my little tweaks.

ETA: Oh, "Import Morph" only seems to create a master channel with no dependencies. What am I doing wrong?

Shouldn't be empty. Only if there is nothing :)

The script checks for empty morphs and skips a morph if no deltas are created.

I tested it some minutes ago with a fresh figure. But to be sure I repacked anything so it reflects the newest changes also (added the current filenames in the tooltips for Ex-/Import; helps if "silent mode" is on). Just re-download please.

If it still does not work for you, there is a small chance that P12 does something I didn't catch. But I'm sure we can find out what goes wrong.

If you import the same obj file you have exported, than the result is zero and no morphs are created :)

Maybe I'm not understanding the concept correctly. I apply some morphs to my figure, export, check in Blender that the morphs have been applied, set all morphs back to zero, import the OBJ that I've previously exported. That's not enough?

Okay, turns out the only thing I really needed to change (on Poser 12.0.500) was the import wxPrepare in WXTools.py to import local_libs.wxPrepare. When loading the script I get an error complaining about a checkbox event with no object that I ignore, then the GUI for the tool appears and I only have to move it to a spot where I can see everything.

I have now managed to import a morph from an OBJ file using the tool. Do I understand correctly that I have to export the unmorphed figure each time directly before I import a new morph? Why is that necessary? I'm assuming some weirdness of the Poser interface?

Ups! Yes, Python 12 has different import logic. But I thought I catched that.... Thanks for finding that out! Will change it tomorrow.

Problem is that if an error is generated while wxPython is active, Poser Python often can't recover. Silly things may happen then :)

No. One export at the start of a session. Pre-morphed or posed. Exports are the Reference used in the modeller. What you add or subtract to this reference is your imported morph. It's late here in germany and I'm pretty tired. I think I do something like a manual the next days (online and "realtime", but in German).

The gist of it (in technical terms) is: morph = numpy.array(imported_vertices) - numpy.array(exported_vertices)

Just checking obj for None before trying to access its name field got rid of that error.

Okay, that's making more sense to me now. It might be useful to make that more explicit in the interface. Maybe separate between reference and regular exports, display the file name of the reference export for the current figure, and if none exists either refuse to import morphs, issue a warning, or automatically create one.

Fixed.

I guess I didn't get enough sleep the last few days and created a pretty creative error.

Everything worked for me as long as I didn't restart Poser. That rarely happens here, because Windows with active Poser runs in a virtual machine on a separate server and is rarely shut down. Except when I brought Poser to a halt using Python :) And that's exactly what happened, after which this script here suddenly stopped working for me too and I got a chance to find the error.

Download the fixed version here.

Thank you so much.  Wonderful that you've written python that runs in both Poser 11 and 12.  That's fantastic.  For the time being I'm doing all my content creation from Poser 11 and most of the scripts that are being written new these days are all for Poser 12 but I don't use it for production, YET!  

any luck getting it to run on the latest version of 12? i keep getting this error:

  File "D:\Poser 12\Runtime\Python\poserScripts\IM_EXPORT\WxMain.py", line 33, in <module>

    reload(im_export)

NameError: name 'reload' is not defined

Sorry for the late replay. I didn't get a notification.

I uploaded a version I'm using with P12 at the end of October:

https://adp.spdns.org/ImExporter_28102022.zip

If you prefer to use the version you used before, mark line 33 as a comment (insert "#" as the first character of the line):

old: reload(im_export)
new: # reload(im_export)

Do so with all lines starting with "reload" if required.

Updated my website. The latest version should work with P11 and P12.

Thank you very much.
