Job Title: 3D Texturing Artist. Department: Immersive Technologies. Location: Vapi, Gujarat. Reports To: 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 new 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.
