I made an ancient Godzilla artifact named Go-Ji-Ra(護慈羅) which is estimated to have been made in 5,600 BC, China.
The original Godzilla mesh is Godzilla – 3d model. I made cracks and overall the mesh by almost the same technique as the way to make excrement (Blender: How to make realistic excrement of any objects (seriously)).
By the technique I already made realistic wooden bark. But I will publish in the near future.
