Hi,
 I am just learning about UDO files and such and have very little experience
with POV scripts. I have worked thru most of the Moray tutorials and for
variety I have downloaded some 3D models from various sites to play with.
The .mdl files from the moray site work great but I have been unable to
render the 3ds files I have imported thru the 3dwin conversion tool. I have
been using the moray/povray 3 choice for conversion. I have been trying to
keep the file names different and am sure that I am not overwriting the .inc
file.
 I think my problem is simpler and perhaps related to POVray script editing
more than moray but I hope someone here can help.

eg:

I have a 10 speed bicycle 3ds file which I import with 3dwin convertor. I
set the lights camera etc. I try a render and find that the materials are
not properly assigned. When I have assigned a material to all the objects
that came with the UDO I try a "test scene". If the test scene says
everything has a material then I retry the render.

 This is where I get stopped cold can someone please ponit me in the right
direction?

POVray appears to begin parsing then it stops and the last message reads:

#declare Bicycle_Bicycle_Smoot15_Ref = object   {
   Bicycle_Bicycle_Smoot15    <------- ERROR

10speed.pov:125:  error: object expected but undeclared identifier
'Bicycle_Bicycle_Smott15' found instead.

Returned from renderer (non-zero return value)


I have looked in the 10speed.pov and seen that the declared objects have a
Ref or _Ref suffix that is not present in the scene which the UDO had been
imported into and which the .pov had been exported from.

I wonder if I need to go in an edit the POV file now that it is exported
from moray?
thanks,
mike

Yep, you do. For some reason, Moray sometimes adds an extra letter to the
name of the object in the reference (the one inside the brackets) What you
need to do is open both the scene (pov) file, and the include file from the
UDO, and check that the names referenced are the same as the ones defined in
the include.I'm not quite sure what is causing the problem, or if there is a
simpler solution. Lutz, anyone, have an idea?

Thanks Krystian,
 I went to the POV file and edited out the suffix '_Ref' which seemed to
have been added. I looked in the new include file and only saw the materials
I assigned in Moray. The objects in the pov file were in the original inc
file where they are descirbed as "mesh"? I tried to render after editing and
saving the pov file but the results were similar to the prvious attempt.

Now the message says:

#declare Bicycle_Bicycle_Smoot15= object   {
   Bicycle_Bicycle_Smoot15    <------- ERROR

C:\Program Files\Moray for Windows\PovScn\bikeA1.pov:121:  error: object
expected but undeclared identifier
'Bicycle_Bicycle_Smott15' found instead.

Returned from renderer (non-zero return value)


  I have no idea what to try to do? It seems the "_REF" suffix wasn't the
thing hanging the render process.
It seems like I am not clear on how the mesh descriptions in the initial
.inc file generated by 3Dwin relate to the objects in my UDO and the
resulting .mdl and .inc files. I am assinging materials to each object on a
local level and the scene test confirms it is OK but POVray seems to be
expecting something other than the original mesh description name. Any help
greatly appreciated.

thanks,
mike mccue

Which one is written in the source, 'Bicycle_Bicycle_Smoot15' or
'Bicycle_Bicycle_Smott15' ?

I think I might have been a little vague on my reply. You need to look
through the include file for the UDO, which delcares the names and shapes of
the objects converted by 3DWin. It should read something like:

#declare Bicycle_Bicycle_Smoot15 = union
{
        mesh {various numbers}
        " repeated several times"
}
Then check the POV file and make sure that when it says:
#declare Bicycle_Bicycle_Smoot15_Ref = object {
    Bicycle_Bicycle_Smoot15   <<<<< This needs to be spelled identically to
the
    material {                                \\\\\\\\ one declared in the
include file.
    something
    }
}

You'll probably have to go thru and check each object that is declared in
the include file. I have no idea if this is a 3DWin problem, or a Moray
problem, as  I haven't used 3D outside of importing to Moray.

Do you have the most recent version of 3ds2pov? I had a problem with it a
month or two ago when the object names in the .inc file were corrupted and
didn't match the names in the .udo file. The author (Thomas Baier) uncovered
a bug, and works okay now. The latest version is available from:

Well, I know I am using either 3DWin or the plugin version that's included
in the 3DWin package. I have no clue if they're updated to match the solo
converter.

3DWin, 3DWinOGL and the Moray plugin use all the same import/export
plugins.
