In this personal research, I was searching a way to make a multi layered viscous parallax effect Material.To achieve this effect I needed a way to blur a texture. If you blur by using a filter, it could become very expensive performance wise. Finally what I found is simply offset the mimap from the texture to have a blurred result.
1 - I used the vertex color for the parallax intensity
2 - result with a parallax offset uvs
3- Adding the MipMap offset using the same Vertex Color
4 - Finally adding the lighting to it
