We are looking for a skilled 3D animation expert to create a library of high-quality animations for a fitness application. The core focus is on user education, specifically showing correct vs. incorrect exercise form. You will be animating anatomically correct male and female 3D models as they interact with our 3D equipment models. Key Requirements: Anatomical Accuracy: Must be able to animate realistic human movement, joint articulation, and posture. Form Correction: Create clear, side-by-side or "wrong-to-right" animations that visually contrast correct exercise form with common mistakes. Visual Overlays: Animate graphical call-outs inspired by our reference video, such as: Highlighting specific muscle groups (target vs. stabilizer). Showing correct/incorrect posture lines and joint angles. Expertise: High-level skill in 3D character animation, rigging, and rendering (Blender, Maya, C4D, or similar). Portfolio: Must have a strong portfolio demonstrating experience with anatomical, fitness, or biomechanical animation. Core Deliverables: Animation Videos: A series of short video clips for each exercise, showing correct form, incorrect form, and the transition between them. Static Graphics: High-resolution "Start" and "End" position renders. "Do's and Don'ts" / "Correct vs. Incorrect" images for use in guides. Source & Asset Files: This is critical. We require all "plug-and-play" assets, including the final rigged models, animation library files, and 2D overlay source files for future in-house use. A step-by-step document explaining the asset library structure and how to use the "plug-and-play" assets to create new video outputs. Required Skills & Experience: Expertise: Proven, high-level proficiency in 3D character animation, modeling, and rigging. Anatomical Knowledge: A demonstrable understanding of human biomechanics, joint movement, and major muscle groups. Portfolio: A strong portfolio that specifically showcases past projects in fitness, medical, or sports animation. Work similar to the reference video is highly preferred. Software: Good knowledge of professional 3D and 2D animation software (e.g., Blender, Maya, After Effects). Communication: Willingness to participate in regular virtual meetings for feedback and revisions.
