Binding a mecanim skeleton to a new mesh

Questions & Answers

Hi,

I am trying to add the skeleton to a new mesh in my scene. The original mesh contains the skeleton and the model moves according to the bone position and rotation. I now have a new mesh without a skeleton. I want to skin this new mesh to this existing skeleton. Below is my code where I copy the bone weights and add the skinned mesh renderer.

It doesn’t work. It deforms my new mesh terribly. Just for background, my new mesh is just an x-scaled version of the old mesh without the skeleton attached.

void Start () 
	{
		vertices = mesh.vertices;

		//Get original mesh bone weights
		weights=new BoneWeight[mesh.vertexCount];
		weights = mesh.boneWeights;
		
		// Get original mesh Renderer
		top = this.transform.Find("Tops").gameObject;
		SkinnedMeshRenderer meshRend = top.GetComponent<SkinnedMeshRenderer> ();

		//Get original mesh Skeleton
		Transform[] originalMeshBones;
		originalMeshBones = meshRend.bones;
		Matrix4x4[] bindPoses = mesh.bindposes;
		for(int i = 0; i < 16; i++){
			bindPoses <em>= originalMeshBones_.worldToLocalMatrix * transform.localToWorldMatrix;_</em>

* }*

* //Blend Mesh settings; tshirt is the blend mesh game object*
* tshirt.AddComponent();*
* tshirt.GetComponent ().avatar = humanAvatar;//human avatar is the original mesh avatar*
* tshirt.GetComponent ().applyRootMotion = true;*

* tshirt = tshirt.transform.Find (“Tops”).gameObject;*

//add skinned mesh renderer component to the new(blend) mesh
* blendMeshRend = tshirt.AddComponent ();*

//copy the bone weights and bind poses and bones
* BoneWeight[] blendMeshWeights=new BoneWeight[mesh.vertexCount];*
* blendMesh.boneWeights = weights;*
* Debug.Log ("vertex 2: " + blendMesh.boneWeights [2].weight2 + “vertex 100:” + blendMesh.boneWeights [100].weight0);*

* blendMesh.bindposes = bindPoses;*
* Debug.Log (“bind poses 0”+blendMesh.bindposes [7].m00);*
* blendMeshRend.bones = originalMeshBones;*

* //tshirt.transform.parent = this.transform;*
* blendMeshRend.sharedMesh = blendMesh;*
* blendMeshRend.rootBone = meshRend.rootBone;*
* }*

why not just bind the bones from a 3D editor ? and switch out the mesh … I like were you’re going with this so I’m guessing there is a reason to make it more complex?
