iOS Nurse Chatbot: 3D Animation & Rigging Specialist Needed
Budget: $1,500 – $3,000 CAD
We are developing an iOS-based virtual nurse chatbot that features a 3D animated nurse capable of showing natural emotional expressions, performing health-related gestures, and engaging users through speech-synchronized facial movements.
We are seeking a Blender specialist experienced in character rigging, blendshape creation, and animation integration using Mixamo. The goal is to produce a lightweight, optimized 3D model (under 15MB) with support for facial expressions, lip sync (visemes), and emotion-based body language. The model will be exported to USDZ format for use in Apple’s RealityKit framework.
Expectations from developer–
• Refine or create a 3D humanoid nurse character using Blender (or improve an existing base mesh)
• Add a full facial rig (using blendshapes/morph targets) to support:
o Lip sync (viseme shapes for common phonemes)
o Emotions: happy, sad, surprised, angry, neutral, etc.
• Integrate Mixamo animations for:
o Basic idle, talking, pointing, walking, and comforting gestures
o Map and clean up Mixamo rig to match facial blendshapes and custom rig if needed
• Optimize the final model for mobile (poly count, LODs, texture compression)
• Export final model and animation sets to USDZ format, ensuring compatibility with iOS (RealityKit)
• Collaborate with the iOS developer on naming conventions and animation triggers
Skills –
• Expert in Blender for character rigging and animation
• Experience creating facial blendshapes / viseme sets
• Familiarity with Mixamo for importing and retargeting animations
• Knowledge of model optimization for mobile performance (polygon count, textures, etc.)
• Ability to export and test models in USDZ format
• Basic understanding of animation logic for mobile apps is a plus
• Deliverables
• Fully rigged 3D nurse model in Blender with clean topology
• Facial rig with 12–20 blendshapes (including visemes and emotions)
• At least 5 body animations from Mixamo, integrated and cleaned up
• Final export of all assets in:
o .blend
o .fbx (for Mixamo)
o .usdz (ready for iOS import)
• Documentation for triggering animations and expressions from iOS code
Timeline –
• Project start: Immediate
• Initial model with rig: Within 2 weeks
• Final optimized export and animations: Within 4 weeks
