I crafted this battery animation in Blender 3D, leveraging the liquid modifier for realistic fluid dynamics and particles to simulate bubbles. The animation's fluid movement was orchestrated using an empty object following a circular path. I optimized the rendering process, dividing the animation into 150 frames rendered with 64 frames each in Cycles. The nuanced ebb and flow of the liquid were achieved through strategic keyframe assignments, resulting in a captivating little and simple battery animation.
