Vellum Fluids surface ripple simulation. Bubbles faked from spheres and noise in SOP, shaded with MaterialX specular + transmission.
Houdini learning experience around Vellum Fluids and the Bubbles SOP. The surface ripples are real Vellum fluid; the rising bubbles are faked from spheres and noise in SOP land. Shading happens in MaterialX with realistic specular + transmission, rendered in Karma.
Techniques
Vellum Fluids — surface ripple simulation
Bubbles SOP — sphere + noise fake for the rising bubbles
MaterialX — specular + transmission for realistic glass-like bubbles
