Hi all! I have a little experience with Moray and POV, and now I
really want to be able to use human figures in my images. I have
Poser 4 and I am having problems getting the figures into POV.
Actually I'd rather get them into Moray so I can model props etc. I
lack expertise with POV's text based interface. A poser figure without
an UV-mapped texture is rather useless so this feature is essential.
I downloaded Poser2POV which is a shareware/freeware DOS command
line utility that is supposed to convert .OBJ files into POV, INCL
and UDO files, complete with associated textures. The author claims that
it will render with texture map provided you use UV-POV or MegaPOV to
render.
When I tried to open the resulting UDO file in Moray it seemed to
work at first; I got the list of body parts (hip, abdomen leg etc) in
the Select panel and a yellow dot in each of the wireframe
perspective views. When I attempted to zoom to the object or zoom to
fit it... doesn't. Its still a yellow dot in all 3 views.
I e-mailed the writers of Pose2POV and got no reply.
I'm considering the Win3D file converter, but that one will not
import textures unless you register it (35 euro) and I really can't
afford it, unless I am *certain* it will work.
How have people solved this problem of Poser to Moray? Any advice?

I have found that if an .obj model consists of more than one mesh(poser
models have a few dozen), Pose2pov will not generate the vertex vectors for
any but the first mesh. The work-around is to find a way to export the .obj
as a single mesh then use a utility like UVMapper to recreate the UV data,
then use Pose2pov (with the -uv to create Megapov mesh2).
I forget whether I used 3dto3d or Rhino to export the models, I think
perhaps it was 3dto3d (recent version). When you export it will giv the
option to merge all the meshes into one.

Interesting.... could you or someone go into a little more detail? This is
helpful but I'm kind of teetering on the edge of understanding.....

Ok, I think I got it now! After you have posed your models, load them in
UVMapper. You can find a link to get UVMapper at www.povray.org . Make any
adjustments to the UV maps you want to make then save the model again in
UVMapper (save the model and the map) When you save the model, check "Export
as Single Group" in the Export Options dialog. Then try running it through
pose2pov.
I accidentally added an extra step in my previous post.
I have also had to make small changes to the .inc file output by pose2pov,
specifically in the texture_list section. This may be because I don't give
the model a texture until after running pose2pov.
Pose2pov would do something like:
.
.
.
texture_list {
0,
texture{ some_texture}
}
...
Then I would change it to:
texture_list {
1,
texture{ my_texture}
}...
This is all through trial and error. I wish I knew a little more about the
syntax of the mesh2 object.
Whether any of this will help get the model into Moray, I'm not sure.
Another tip: If you do get the model into your scene in Moray, you can move
the line invoking the .inc file from your .pov scene to another .inc file
(that will not be modified by moray) then delete the object from your moray
scene. Although you won't see the wireframe object in your scene, it will be
there and you can include more objects without using up all your memory in
moray.

Very frustrating!
I followed your suggestions with UV mapper. The resulting obj file from UV
mapper was run through pose2pov. When I tried to open the resulting UDO file in
Moray nothing at all happens. It sees the file but doesn't process it at all. No
object appears.
Have you tried this lately yourself? I had UV mapper save it as a single mesh
with UV data.
Then I went off and tried using MegaPOV to render the POV and INC files also
generated by pose2pov. After some adjustments to library paths etc. it works
perfectly, rendering and texture mapping the figure from the .png files.
However, its going to be impossible for me to model clothing and a scene around
the figure without using Moray. I was really looking forward to using Moray's
splines to make clothing and jewelery.....
I tried the version 1.0 Moray plugin win3dwin of T. Baier. That imports from the
original .obj file and gives a one mesh UDO wireframe figure in Moray. However,
I don't know how to texture map that, and of course it has no constituent parts.
I can of course render it with a solid color, but what use is that?

Yes, I just did try to do this and you are right; pose2pov does not create a
useable .udo. I had to use a different program to create the .udo then
replace the .inc with the one created by pose2pov.
> Very frustrating!
Very frustrating, indeed! I'm sure that if we have some patience there will
soon be more options for getting .obj files into moray.

However,
It seems to me that one of Thomas Baier's programs did export mesh2 files. I
have version 3.5 which (probably not the most recent) If mesh2 support were
added to his 3dto3d moary plugin, I'm sure we can all agree it would make
life easier.

I think the .inc you created here is a standard mesh of smooth triangles,
which has no uv data.
I have the source code for pose2pov. I am now curious to see why these
things don't work. Maybe it's an easy fix (yeah, right.)

I've just experimented with 3DWin 4.1 (see the thread 5 up from this one. As you
will see from that thread the unregistered version seems to produce an UDO that
Moray recognises and has individual meshes for the body parts. The registered
version apparently produces UV data and has full material conversion, but I
haven't been able to confirm this. If I was *sure* that it imports Poser objects
easily to Moray with full texture info and separate body parts I'd be willing to
pay the money for it (35 Euros). Its not a Moray plugin, but it seems pretty
user-friendly. It needs more MegaPOV support and some conveniences like sorting
out the many files it produces from the conversion process into the correct
Moray/POV directories.

Hi Simon Lacey, you recently wrote in moray.win:

Hmm. Can you post the first 15 or so lines of the UDO file that
Poser2POV generates? Maybe it's faulty.

I found the faulty logic in the pose2pov program and posted the results in
p.b.u. Here is the entire .udo file the origial version created when trying
to convert a standard P4 character:
IncludeFile 'figure1.inc'
Name 'poser_object'
And the-b-b-da-tha-be-da-that's all folks!
Like I said before, there seem to be other problems too. I thought this
would be an excellent opportunity to try and figger out the Moray SDK. I
downloaded it a couple of mothes ago and have not yet had the strength of
heart to begin experimenting with it. Do you have any tips for getting
started, Lutz? I am still a COM virgin.
