Modifying SkinnedMeshRenderer.sharedMesh.uv Doesnt Reset after Stopping game.

I’m modifying SkinnedMeshRenderer.sharedMesh.uv of a model to change the vertices trying to animate them. However when I stop the game the changes stay on the model, and starting the game again the changes are still there. How do I prevent this from happening?

Running the app a second time will offset the texture again.

Code:

SkinnedMeshRenderer meshRend = GetComponent<SkinnedMeshRenderer>();
mesh = meshRend.sharedMesh;

uvs = mesh.uv;
for(int i = 0; i < uvs.Length; i++)
{
          uvs <em>= new Vector2(uvs_.x - 0.01f, uvs*.y - 0.01f);*_</em>

}
mesh.uv = uvs;

So I think I found a workaround, by copying the mesh, modifying the copy, then assigning that to the SkinnedMeshRenderer.

Code:

SkinnedMeshRenderer meshRend = GetComponent<SkinnedMeshRenderer>();
Mesh mesh = meshRend.sharedMesh;
var mesh2 = Instantiate(mesh);

Vector2[]  uvs = mesh2.uv;
for(int i = 0; i < uvs.Length; i++)
{
	uvs <em>= new Vector2(uvs_.x - 0.01f, uvs*.y - 0.01f);*_</em>

}
mesh2.uv = uvs;

meshRend.sharedMesh = mesh2;
