Job description

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.
