Need a 3D engineering-style animation (not cartoon / not marketing style). Animation should show a pressurized pipe with a visible crack and water leak. Show installation of a multi-layer composite wrap around the pipe. Section cut view must clearly show three layers: outer structural layer, hydrogel bead matrix, inner membrane. Water should migrate through the membrane and activate hydrogel beads. Beads must swell realistically (soft material deformation, not simple sphere scaling). Expansion should be constrained by outer layer and redirect pressure inward. Show leak gradually reducing as pressure seals the crack. Include micro-scale zoom showing bead hydration and gel-like expansion. Visual style must resemble SolidWorks / FEA / engineering simulation outputs. Clean white background, realistic materials, subtle pressure/stress visualization. Deliver 1080p MP4 animation + high-resolution still renders + source files. Share portfolio of similar technical/engineering animation work.
