Realistic Water Simulation with Bubbles – Seamless Loop
At AquaVFX, we specialize in high-quality fluid simulations for VFX, animation, and motion design. This project was a personal study focused on improving simulation and rendering techniques, resulting in a 100-frame seamless looping animation.
Key Features:
✅ Realistic Water Simulation – Smooth and natural fluid motion
✅ Floating & Underwater Bubbles – Interacting dynamically with the liquid
✅ Perfect Loop Animation – Ideal for motion graphics and VFX sequences
✅ Created in Houdini & Rendered in V-Ray – Industry-standard tools for high-quality results
🔹 Preparing for a Fluid Simulation 🔹
Before running a fluid simulation, it’s essential to prepare the geometry properly. Here’s the initial setup for this project:
✅ Imported the model into Houdini
✅ Refined the mesh for better collision accuracy
✅ Filled the interior with particles to initialize the simulation
Proper collision setup ensures realistic interactions between the fluid and the object. Stay tuned for the final result! 🚀
🔹 Adding Motion & Turbulence to the Fluid 🔹
In this step, I focused on controlling the movement of the fluid inside the container. Using DOP Network nodes, I added:
✅ Rotational motion for a natural swirling effect
✅ Turbulence & randomness to make the movement more organic
✅ POP Metaball Force to create localized forces within the fluid
These forces help achieve a more dynamic flow. Can’t wait to share the final render! 🚀
🔹 Creating a Seamless Loop for Mesh Animation 🔹
To make the fluid simulation loop perfectly, I used a blend technique with VDBs:
✅ Time Shifted the animation 100 frames back
✅ Converted both original & time-shifted meshes to VDB
✅ Used Volume Mix to gradually blend between the two states
This ensures a smooth transition, allowing the animation to seamlessly repeat after 100 frames. 🔄
🔹 Looping Bubbles in Fluid Simulation 🔹
To make the bubbles loop seamlessly, I used a randomized removal technique:
✅ Time-shifted the animation 100 frames back (same as the main mesh)
✅ Randomly deleted some bubbles in the original animation
✅ Restored randomly deleted bubbles from the time-shifted version
This creates a natural, continuous cycle, making the bubbles appear dynamic yet perfectly looped! 🔄✨
