I need a high-accuracy, engineering-grade 3D mechanical animation for my patented Automatic Touchless Building & Window Washing System. The animation will be used for government demonstrations, licensing partners, and investor presentations therefore, it must clearly show real mechanical behavior, realistic motion, spray physics, PLC automation, sensors, and remote-control operation. WHAT THE ANIMATION MUST SHOW The animation must follow my full storyboard (approximately 16 scenes) and include: Complete guide-rail system (guide railway columns, belts, pulleys, motor gearboxes). Single and slide carriages with accurate movement tolerances. Spray arm: high-pressure water, chemical, and air jets. Water recovery system (collector channels) under each window section. Storage tanks, pumps, tanks refill system, and pipe movements. Wipers, sensors, PLC-based automation, and remote monitoring interface. Exterior + interior cleaning workflow. Realistic building-scale visualization (daytime and night scenes). The final animation should look technically believable, not cartoonish. ANIMATION STYLE & PIPELINE The final product must include: Engineering-accurate motion. Realistic fluid/spray simulation. Realistic materials, reflections, and environment. Smooth camera transitions. Text overlays. Sound effects + Voice-over timing (I provide the script). Pipeline expected: Animatic (rough blocking). Engineering pass (accurate mechanical motion). Shading / Lighting. Final render. Sound + VO sync. DELIVERABLES REQUIRED At the end of the project, the freelancer must deliver all source files, including: 3D models (native, plus FBX). Rigging files / constraints. Fluid & particle simulation caches. Textures, materials, HDRIs. Project files (Blender, 3ds Max, Maya, C4D, etc.). Node networks / custom scripts. Final rendered video (4K + compressed version). PAYMENT TERMS One full payment will be released ONLY after the final approved animation is delivered. No partial milestone releases. WHAT I PROVIDE Full storyboard (16 scenes). Patent drawings. Reference sketches. Voice-over script Technical notes Ideal Candidate: I am looking for someone with strong experience in: - Mechanical animation. - Industrial/engineering visualization. - Fluid simulation. - Realistic rendering. - Automation/PLC visualization. - Product animation. - Strong portfolio of mechanical/industrial 3D animation. - Ability to work with engineering accuracy. - Excellent communication skills. - Comfortable signing an NDA before receiving assets. - Delivers clean, realistic rendering (no cartoon style). Budget Range: $750–$1,500 depending on experience and quality. To Apply, Please Send: - Your best mechanical/industrial animation samples - Timeline & workflow explanation - Software/tools used - Confirmation that you accept NDA - Estimated delivery within 15–25 days
