3D Designer

Job Description

Octathorpe Technologies is seeking a skilled 3D Designer with strong expertise in creating highly detailed and optimized product models such as shoes, furniture, and accessories. The ideal candidate is proficient in Blender for 3D modeling, UV unwrapping, baking, and exporting GLB files, alongside expertise in Substance Painter for physically based rendering (PBR) texturing and ORM map packing. This role requires a solid understanding of real-time PBR workflows and the capability to produce clean topology models optimized specifically for web applications, with triangle counts between 10,000 to 50,000. Familiarity with the glTF/GLB format and Draco mesh compression is essential to ensure efficient asset delivery in interactive environments. The candidate must be able to accurately replicate products from photographic references, demonstrating attention to detail and precision in 3D asset creation. This position is ideal for a 3D Designer with at least two years of relevant experience who is passionate about product visualization and digital craftsmanship. While no team management responsibilities are required, the candidate should possess excellent independent work habits and the ability to enhance the quality and performance of 3D assets within the companys technology ecosystem. Knowledge of WebGL frameworks such as Three.js, texture atlasing, UV layout optimization, and retopology from high-poly or AI-generated models will be advantageous. A strong portfolio highlighting expertise in leather goods, footwear, or hard-surface products will support candidacy for this role.
Responsibilities
 

• Create precise and visually appealing 3D models of products including shoes, furniture, and accessories using Blender with clean and efficient topology optimized for web-based use.
• Perform detailed UV unwrapping and mapping to prepare models for high-quality texturing.
• Develop realistic and physically accurate textures using Substance Painter following the PBR workflow, including proper ORM map packing.
• Export models in GLB format while applying Draco mesh compression techniques to minimize file sizes without compromising detail or visual fidelity.
• Ensure models are optimized within polygon limits suitable for real-time rendering environments, specifically between 10,000 and 50,000 triangles.
• Accurately replicate product designs from photo references to maintain brand consistency and product authenticity.
• Understand and implement real-time rendering requirements to facilitate smooth visualization across web platforms.
• Collaborate with the development team to test 3D assets in WebGL viewers such as Three.js and address any technical issues related to model performance or appearance.
• Apply knowledge of texture atlasing to maximize texture efficiency and reduce draw calls in digital environments.
• Implement retopology techniques where necessary to create low-poly models from high-poly or AI-generated meshes for improved performance.
• Maintain comprehensive documentation of modeling, texturing, and optimization workflows to standardize asset production.
• Stay updated on the latest trends and tools within the 3D design industry relevant to product visualization and real-time rendering.
