Hy all! How can I change the lookout of an object?
I tried to change the mesh, but only the meshfilter changed, I can see the same ingame with this code:

this.gameObject.GetComponent().mesh=m.mesh;

where m is a MeshFilter variable.
Tried this too:

GameObject i=Instantiate(Resources.Load("spy",typeof(GameObject))) as GameObject;
this.gameObject.GetComponent().mesh=i.GetComponent().mesh;

this didn’t achieved anything…
Tried this:

	Vector3 pos=this.gameObject.transform.position;
	Vector3 rot=this.gameObject.transform.eulerAngles;
	Vector3 sc=this.gameObject.transform.localScale;
	Destroy(this.gameObject);
	GameObject g=Instantiate(Resources.Load("spy"),pos,Quaternion.identity) as GameObject;
	g.transform.localScale=new Vector3(822.7944F,822.7944F,822.7925F);

It achieved the old object has destroyed, but the new one has the same size as the original, but looks like squashed. The collider has good size too.

I don’t know what should I do to change the lookout of an object… Please help me!

You can replace the object’s mesh this way:

(GetComponent<MeshFiter>() as MeshFilter).mesh = newMesh;

If the object has a mesh collider, you must update it too:

(GetComponent<MeshCollider>() as MeshCollider).sharedMesh = newMesh;

NOTE: Be aware that the mesh collider update is a heavy operation, and may make your game crawl like a wounded snail if done each Update!
