Thanks, I've compiled a list of R12 Melange bugs that I've encountered so far.  Some have no solution:
1. AddJoint() always return -1.  No workaround.
2. RemoveJoint() never removes a joint, even for a good joint listing.  No workaround.
3. JointRestState matrices are ignored (or not calculated) when loading Melange-written files into Cinema4D.  No workaround.
4. GetMg() returns an incorrect matrix.  Workaround: must use GetMl() to build world matrix yourself.

Thanks!  I tried it out, and my joints are getting added now.
One last question, when I import a C4D file created by Melange (with joints) into Cinema4D, the mesh is still distorted.
And I've called CalculateBoneStates() on the all joints to make sure they have valid matrices.
I've printed out all matrices in JointRestState, and they all look good.
In the C++ SDK, I call EventAdd() whenever an object needs updating, but Melange has no such function.
Is there a final function to call to make sure my Melange document (internal flags and data) is up-to-date?
Because, for some reason, Cinema4D is still ignoring my JointRestState matrices.

hi rootbender,

sorry for the delay. did you succeed in the meantime?
there're 4 functions to call, SetGeomMg(), AddJoint(), SetJointResState() and then CalculateBoneStates() (pass NOTOK to calculate it for all joints).

did you try this within the cinema sdk and was it working there?

could you send me the testscene you have written with melange and cinema has problems with?

cheers

Hi,
I tried calling CalculateBoneStates with NOTOK, but it has no effect.
 
The mesh is still distorted on imported.  Cinema4D behaves as if it's using the Identity matrix for
all bind matrices.  But, I checked, they are not identity.

hi!

could you try your code with the cinema sdk please? this would be very helpful to figure out if this a melange problem only or a generaly issue with the sdk.

i think i can have a look and try by myself tomorrow to create a setup like yours with melange.

cheers

Yes, I also have the same problem with the C++ SDK.  The mesh distortion looks exactly the same as Melange.
 
In fact, the distortion is very consistent.  It doesn't change at all.  It doesn't matter what values
I plug into the bind matrices, it always comes up looking the same shape.

hi,

thanks for checking this. could you provide us a complete code snipped please? the polygon object we could load but we have to know how do you setup the joint, skin object and the weight tag. i think this would be the fastest way to help you. you can send the code to my email (we'll keep it confidential if you want).

Source code was sent, so I hope you got a chance to look at it.
Do you know if this is something that I can fix myself, or is it a C4D problem?

Hi,
I just discovered I was incorrect about the C++ SDK.  It does work there.  I created a working example
from static data and it worked.
It only fails when reading files created by Melange.
In your test code, I modified it so it loads melange files.  The mesh comes in distorted.

  
Bool SubDialogTest::Execute(BaseDocument *doc)  
{  
 BaseDocument *tmpDoc = LoadDocument(Filename("example_from_melange.c4d"),SCENEFILTER_OBJECTS,NULL);  
 if (!tmpDoc) {  
    return FALSE;  
 }
 InsertBaseDocument(tmpDoc);  
 tmpDoc=NULL;  // c4d takes control
 EventAdd();
 return TRUE;  
}  

For some reason, the bind pose matices are being ignored.

hi,

thanks for clarifying this. so it seems to be an issue in melange.
could you send me this static data example please? i've to debug these functions in melange.

thanks for the code example. i've had a look and it works in melange. i've sent you necessary changes i did to your code per email. please have a look and let me know if it works and what changes you had to make.

Thanks, I tried your code, but I still get the same distorted mesh.  I compared my scene_OUT.c4d file with yours,
and they don't match.
I sent you my scene_OUT.c4d file and the code used.
btw, your scene_OUT.c4d works great, but I can't explain why mine is different.
My commandline project is compiled in Release mode under Intel/PC platform (Windows XP), if that matters.
