Blender Character Rigger & Animator for Real-Time GLB Fitness App (glTF export required)

Blender Rigger/Animator for Real-Time Fitness App We’re looking for a Blender rigger/animator to help build a low-poly animated human mannequin for a posture and fitness app. Please read this first: the deliverable is not a render. We need a working `.glb` file that loads and plays in a web viewer using three.js. It should stay under roughly 2 MB and keep the animated materials working. If your portfolio is mostly polished Blender renders, but you haven’t shipped rigged, game-ready glTF/GLB assets for real-time use, this probably is not the right fit. What we’re building We’re building a commercial posture and fitness app where users can rotate a low-poly human mannequin on their phone. The mannequin demonstrates movement assessments, corrective drills, and breathing/restoration exercises. One important feature is muscle highlighting. During each movement, the active muscle group should change to red/orange while the rest of the body stays gray. Where we are now We already have a starting point ready: * Blender files with blockout mannequins and about 24 keyframed animations * 7 movement assessments and 17 breathing/restoration drills * Two Python build-kit files that define the joint hierarchy, muscle-zone materials, camera/overlay conventions, and naming system * Reference videos and written protocols for every exercise Your job is to turn the blockout into a production-ready asset. That means a proper armature, clean skin weights, a low-poly human mannequin with a normal head, roughly 5k to 15k tris, cleanly retargeted animations, and GLB exports that work in-app with the muscle highlighting intact. First job: paid test project We’ll start with one paid test task before moving into the full library. We’ll give you one assessment. You’ll deliver: 1. A rigged low-poly mannequin with armature and skin weights 2. The assessment animation retargeted cleanly onto it 3. A working `.glb` that loads in a web viewer and plays correctly 4. Red/gray muscle material swapping intact 5. File size under roughly 2 MB If the test goes well, there is ongoing work for the full animation library and new drills as the app grows. Skills needed * Blender * Character rigging * Skin weighting * glTF/GLB export * 3D character animation * Low-poly character modeling Bonus if you have experience with three.js, react-three-fiber, real-time/game-ready assets, anatomy, fitness, or biomechanics. We provide all the exercise references and protocols, so you do not need to be a biomechanics expert. How we work We move fast and iterate often. Feedback will be specific and direct. We prefer short async updates like screenshots, screen recordings, clips, and GLB files instead of long calls. This is a good fit if you like clear briefs, fast feedback, and shipping working files instead of spending forever polishing renders. How to apply In the first line of your application, link a real-time glTF/GLB you have shipped. This can be a Sketchfab embed, a three.js/model-viewer demo, or a downloadable `.glb`. Then write one or two sentences explaining how you would set up a low-poly human so individual muscle groups can be recolored at runtime. Applications without a GLB link will be skipped.
