3D Texturing Artist

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 (P ) 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. P  Texturing & Material Creation

• Create production-ready P  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 P  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…
