Blender Fluid Fill Logo is one of the most eye-catching ways to animate a brand identity. If you want to bring your logo to life with a dynamic fluid simulation, this tutorial, “Blender – Fill Logo with Fluid,” walks you through the entire process, from preparing your SVG to setting up the fluid simulation and rendering a stunning final result. Learn the complete workflow to create this dynamic fluid fill logo effect in Blender, covering SVG preparation, the Boolean modifier, and a realistic liquid simulation.

Phase 1: Preparing Your SVG and Creating the Blender Fluid Fill Logo Imprint
The first and most critical step is getting your source logo geometry ready to contain the fluid. This is often the part of the simulation that beginners overlook.
- Import and Prep (00:00): Open a new file and import your SVG logo. Since SVGs often import as curves, you’ll need to clean up the shape. Be sure to join any elements you want to be treated as a single mesh, scale it up to a manageable size, and extrude it to give it volume.
- Convert and Remesh (00:20): Crucially, convert the logo to a mesh (usually done by right-clicking in Object Mode and selecting ‘Convert to Mesh’). Then, apply a Remesh modifier. This step is non-negotiable; it creates a uniform, clean topology essential for preventing artifacts and ensuring a smooth, accurate fluid simulation.
- Create the Basin (00:38): Now, we must carve out the internal space for the liquid. Add a simple cube, scale it down to the internal dimensions of the logo, and position it to define the exact shape of the water’s surface. Use the Boolean modifier on your logo object with the cube as the target and the Difference operation. This action permanently carves an imprint in the logo mesh, creating the custom basin where the fluid will sit. Convert the cube object to a mesh and remesh it as well for consistency.
Phase 2: Configuring the Blender Fluid Simulation Domain
With the container ready, it’s time to set up the powerful Blender fluid simulation system, known as Flip Fluids (or Mantaflow in modern Blender versions).
- Domain Setup (00:56): Add a cube to your scene and immediately apply the Quick Liquid effect (found under the Object menu). This cube automatically becomes the Domain, which acts as the boundary and computational area for the entire simulation. Scale the domain so it perfectly encloses your logo object, leaving a small buffer of space.
- Inflow Emitter (01:15): The initial small cube is your fluid emitter. Move it so it sits inside the logo basin. Change its fluid type from ‘Flow’ to Inflow. An Inflow object continuously generates fluid throughout the simulation. For better control over where the liquid appears, you can duplicate this emitter to different points within the logo’s cavity.
- Bake Settings (01:25): The quality of your Blender Fluid Fill Logo result depends heavily on these settings. Increase the domain’s Resolution to $\mathbf{200}$ (higher resolution yields more detail but takes longer). Change the bake type to All so the simulation includes mesh data. Finally, set your desired animation length (e.g., set the last frame to $\mathbf{120}$) and hit Bake Data.
Phase 3: Lighting, Materials, and Final Polish
A perfect simulation needs a compelling presentation. Use these steps to polish your scene:
- Initial Scene Setup (01:40): Add a plane underneath the entire setup to serve as a floor. Enhance the environment by introducing an HDRI environment texture for realistic, diffused lighting. Give the floor a base shader, and initially, give the liquid a simple metallic material for contrast.
- Camera and Depth (01:54): Add a camera, set it to an orthographic lens, and apply slight depth of field (DOF). Using a shallow DOF can make the result more professional and draw the viewer’s eye exactly where you want it—to the fluid.
- Adding Dynamics (02:02): To avoid a static, glass-like pour, introduce subtle motion. Move the fluid emitters down slightly, and add a Turbulence force field with a value of $\mathbf{0.5}$. This small addition will introduce small ripples and dynamic movement to the fluid surface. Remember to re-bake the entire simulation after adding the force field.
- Final Shaders (02:18): Complete the look by giving your floor a detailed material, like a brick texture, and creating a sophisticated, custom metallic shader for the liquid to achieve the final, high-impact Blender Fluid Fill Logo animation.
The result is a compelling animation where your logo is dynamically filled by a realistic metallic fluid!
