An effect made in Houdini that changes a stone material into a marble material on a statue. A particle system is also created to add more visual appeal. Both the material change and the particle system are affected by a moving noise texture flowing onto the model.
I got the 3d model of the statue from this link on sketchfab : https://sketchfab.com/3d-models/frank-0eb1f1757349489eab05a0f03cff5b46
