XR Lead Experience

2–5 Years Job Purpose: To create high-quality, physically based (PBR) textures and technical art maps for a physics-driven robotic surgical training simulator built in Unity. The role will be responsible for texturing surgical instruments, medical devices, operating-room environments, metals, plastics, sterile surfaces, and organic tissues while maintaining consistent texel density, material quality, memory efficiency, and real-time rendering performance suitable for workstation GPU environments.

Key Responsibilities: 1. PBR Texturing & Material Creation • Create production-ready PBR textures for surgical instruments, medical devices, robotic components, operating-room environments, and organic assets.

• Develop high-quality Albedo/Base Color, Normal, Metallic, Roughness/Smoothness, Ambient Occlusion, and other required texture maps.

• Create realistic material definitions for metals, plastics, glass, rubber, ceramics, surgical surfaces, sterile materials, and biological/organic tissues.

• Develop textures from 3D model and sculpt handoffs while preserving required surface details and visual fidelity.

• Ensure physically accurate material response appropriate for real-time surgical simulation.

2. Channel-Packed Texture & Technical Art Workflows • Create and maintain channel-packed textures to optimize GPU memory and material performance.

• Implement project-specific packing standards such as: R = Metallic G = Ambient Occlusion A = Smoothness • Ensure gloss/smoothness and roughness maps are correctly converted and exported according to the defined Unity pipeline.

• Validate packed textures for accuracy, consistency, and compatibility with Unity materials.

• Support optimization of texture memory through efficient channel usage and resolution management.

3. Trim Sheet & Modular Asset Texturing • Develop and maintain trim-sheet workflows for modular surgical instruments, robotic components, and environment asset families.

• Create efficient UV layouts that maximize texture-space utilization.

• Ensure consistent material appearance across assets using shared trim sheets and reusable texture libraries.

• Support modular asset development while minimizing redundant texture memory and draw-call overhead.

4. UV Mapping & Texel Density Management • Create and optimize UV layouts using Maya, Blender, or equivalent tools.

• Maintain consistent texel density across the complete asset library.

• Ensure appropriate UV packing and utilization based on asset importance and camera visibility.

• Support second UV channel creation for lightmap UVs where baked lighting is used.

• Identify and resolve UV overlaps, stretching, distortion, seams, and inefficient texture-space utilization. 5.

Substance

Painter / Designer Workflow • Create production-ready textures using

Substance Painter, Substance Designer, or equivalent PBR tools .

• Build reusable Substance materials, procedural textures, and graphs for frequently used materials and asset families.

• Generate textures from high-poly sculpt and low-poly model workflows.

• Incorporate baked information such as curvature, cavity, AO, thickness, and other maps into material creation where required.

• Maintain reusable and scalable material libraries for the simulation project.

6.



Medical, Surgical & Organic Material Development • Develop realistic material definitions for surgical instruments, medical devices, operating-room surfaces, and organic tissues.

• Create material variations for: Stainless steel and surgical metals Medical-grade plastics Rubber and silicone Glass Sterile OR surfaces Soft tissues Anatomical structures Other medical/surgical materials • Work with clinical and visual SMEs where required to ensure appropriate representation of medical materials and surfaces.

• Support the development of realistic tissue characteristics including surface variation, subtle color variation, roughness, folds, wrinkles, and tension-related details. 7.

Unity

Look-Development & Validation • Validate materials and textures directly within Unity to ensure correct visual output and real-time performance.

• Work closely with Look-Dev Artists, Technical Artists, Unity Developers, and Simulation Engineers to resolve material and rendering issues.

• Verify correct interpretation of Normal, Metallic, Smoothness/Roughness, AO, and other texture maps within Unity.

• Evaluate materials under different lighting conditions and camera distances relevant to surgical training scenarios.

• Support optimization for workstation GPU budgets without compromising required visual quality. 8.

Technical

Art & Performance Optimization • Optimize texture resolution, compression, channel packing, material complexity, and texture memory usage.

• Create instancing-friendly materials and reusable texture systems where required.

• Support efficient texture workflows for modular environments and large asset libraries.

• Identify performance bottlenecks related to textures and materials and recommend appropriate solutions.

• Work with Technical Artists to maintain consistent rendering and material standards across the simulator.

9. Cross-Functional Collaboration • Work closely with 3D Modelers, Sculpting Artists, Look-Dev Artists, Technical Artists, Unity Developers, Simulation Engineers, and Clinical SMEs.

• Receive and process asset handoffs from modeling and sculpting teams.

• Collaborate with Look-Dev and Technical Art teams to establish and maintain material standards.

• Participate in regular art pipeline reviews and production meetings.

• Communicate texture quality issues, dependencies, and technical blockers proactively.

• Explore recent PBR, procedural texturing, technical-art, and real-time rendering techniques.

• Contribute to improving texture production efficiency, material realism, and GPU performance.

• Stay updated with emerging workflows in Substance, Unity, medical visualization, XR/VR/AR, gaming, and real-time simulation.

• Contribute to the development of reusable material libraries and procedural workflows for future simulation projects.
