In this setup, a Pyro smoke simulation is driving the motion of a curve by using its velocity field to advect the curve points. As the curve moves through the flow of the smoke, it naturally follows the swirling, turbulent patterns created by the simulation. To maintain consistent detail throughout the animation, the curve is resampled on every frame. This prevents the resolution from stretching or diminishing over time, ensuring smooth motion and clean geometry.
This technique is great for creating organic, fluid-driven motion paths that react realistically to smoke or other velocity-based simulations. It’s especially useful in VFX workflows for trails, wisps, motion graphics, or stylized particle-driven effects.
