CG COOKIE presented an unusual and creative approach to water visualization in Blender, achieved entirely without fluid simulation. Instead, the effect was crafted using Blender’s physics tools.
The creators employed Dynamic Paint, Boolean modifiers, and constraints to simulate realistic water behavior inside a bottle. The result is a convincing liquid effect that mimics real movement without the heavy processing of traditional fluid sims.
CG COOKIE shared a comprehensive, step-by-step tutorial explaining the full technique:
