Question Skinning pass on skinned mesh renderer

I am trying to a achieve a smearing effect (example) on meshes and I am doing it via compute shader. While it works fine for a normal mesh. I can't get it to work on a skinned mesh. The skinning process seems to overwrite all changes done by the compute shader. Is there any way to execute my compute shader after the skinning process?

 

I did some more digging and after installing RenderDoc I noticed that my compute shader allegedly has no bytebuffer set. Even though I set the buffer in LateUpdate.

Spoiler: Late Update Code

Code (CSharp):

1. private void LateUpdate() {
2.         GraphicsBuffer vertexBuffer = null;
3.         if (renderer.vertexBufferTarget.HasFlag(GraphicsBuffer.Target.Raw)) {
4.             vertexBuffer = renderer.GetVertexBuffer();
5.  
6.             shader.SetBuffer(kernelID, "vertices", vertexBuffer);
7.             shader.SetInt("stride", vertexBuffer.stride);
8.             shader.SetInt("vertexCount", vertexBuffer.count);
9.         } else {
10.             Debug.LogWarning("Vertex buffer isnt set as raw!");
11.         }
12.  
13.         shader.Dispatch(kernelID, Mathf.CeilToInt(renderer.sharedMesh.vertexCount / 256f), 1, 1);
14.         if (vertexBuffer != null) vertexBuffer.Dispose();
15.     }

Spoiler: RenderDoc

 

Turns out GPU skinning was turned off. I assumed it was on. Turning it back on fixed the issue.
