Hi!

I want to do is merge the scene hierarchy from two different FBXs into a single FBX. What’s the right way to do that?

So,

Let file1.fbx be

root1
|---child11
|---child12
|--child13

and let file2.fbx be

root2
|---child21
|---child22
|--child23

What is the right thing to do, such that I can have a file with say either a dummy root

root
|-root1
|   |---child11
|   |---child12
|   |--child13
|-root2

    |---child21

    |---child22

    |--child23

Or just this:

|-root1
|   |---child11
|   |---child12
|   |--child13
|-root2

    |---child21

    |---child22

    |--child23

I do not need the code, just pointers to how to do it will be very very helpful!
Please help!
Thanks a lot in advance,
Arjun

Always check the FAQ before asking questions! :)

I still wanted to ask, that my source scenes are modified, isnt it? Can I not do something such that it is not destroyed?

InitializeSdkObjects(mAnimShapeFamily.getSDKManager(), mAnimSceneFBX);

 KFbxNode *allRoot = mAnimSceneFBX->GetRootNode();

 for(unsigned int i0 = 0; i0 < opModels->size(); i0++)

 {

 o_3dModel *model = (*opModels)[i0];

 KFbxScene *testScn = model->getFBXScene();

 // Move node tree to reference scene.

 int lNbChildren = testScn->GetRootNode()->GetSrcObjectCount();

 for (int i = 0; i < lNbChildren; i++)

 {

 KFbxNode* lChildNode = testScn->GetRootNode()->GetChild(i);

 // Attach child node to ref scene's root node.

 lChildNode->ConnectDstObject(mAnimSceneFBX->GetRootNode());

 }

 // Detach all children from root node

 testScn->GetRootNode()->DisconnectAllSrcObject();

 // Move other objects to reference scene

 int lNbSceneObj = testScn->GetSrcObjectCount();

 for (int i = 0; i < lNbSceneObj; i++)

 {

 KFbxObject* lObj = testScn->GetSrcObject(i);

 if (lObj == testScn->GetRootNode() || *lObj == testScn->GetGlobalSettings())

 {

 // Don't move root node or global settings: these objects are created for every scene.

 continue;

 }

 // Attach object to ref scene.

 lObj->ConnectDstObject(mAnimSceneFBX);

 }

 testScn->DisconnectAllSrcObject(); // Disconnect all scene objects.

 }

 SaveScene(mAnimShapeFamily.getSDKManager(), mAnimSceneFBX, "data/tmp/allScene.fbx");

How about create a new scene and when you move nodes from file1 and file2 to this new scene, always clone a copy of the nodes, and do not touch the original nodes in file1 and file2?

I did not test it myself, just some idea here. :)
