• Work with clinical and medical experts to understand surgical workflows, instrument usage, and anatomical requirements.
\n
• Incorporate clinical and technical feedback into 3D asset development.
\n
• Ensure appropriate visual and dimensional accuracy for surgical training and simulation applications.
\n

4. CAD, Reference & Mesh Preparation

\n
• Convert and optimize CAD/reference data for use in real-time 3D environments.
\n
• Perform basic CAD cleanup, mesh optimization, retopology, and geometry preparation.
\n
• Prepare clean meshes for handover to sculpting, texturing, rigging, animation, and technical-art teams.
\n
• Perform basic UV layout and ensure assets are appropriately structured for downstream texturing.
\n

5. Cross-Functional Collaboration

\n
• Work closely with 3D Artists, Technical Artists, Unity Developers, Simulation Engineers, Clinical Experts, and XR teams.
\n
• Participate in regular production and pipeline review meetings.

\n
• Proactively communicate technical challenges, dependencies, quality issues, and production blockers.
\n
• Contribute to improving the overall 3D production pipeline and asset development standards.
\n

6. Documentation, Version Control & Quality

\n
• Follow established asset naming, folder structure, modeling, and production standards.
\n
• Maintain asset versions using Git, Git LFS, or the approved Digital Asset Management (DAM) workflow.
\n
• Document polygon budgets, LOD structure, asset versions, references, and known issues where required.
\n
• Perform quality checks on geometry, topology, scale, pivots, naming, and performance before asset handover.
\n
• Ensure timely delivery of assets according to project milestones and production requirements.
\n

7. Innovation & Learning

\n
• Contribute to the development of next-generation immersive surgical training and robotic simulation technologies.
\n
• Explore new techniques for 3D modeling, optimization, visualization, and real-time simulation.
