What We're Looking For

If you find yourself obsessing over imperfect refractions, feel compelled to fix unnatural scratches, and are willing to fine-tune a material's roughness value ten times over — welcome to join us in pushing the realism of our product models to the extreme. 我们对你的期待 如果你看到不完美的折射会反复调试，发现不自然的划痕就想要修正，愿意为一个材质的 roughness 数值较劲十遍——欢迎加入我们，一起把商品模型的真实感打磨到极致。

Responsibilities

1. Model Refinement: Optimize topology, repair UVs, and enhance details of product models to ensure asset quality meets photorealistic rendering standards;
2. Material & Lighting Optimization: Accurately replicate complex materials (Subsurface Scattering/Multi-layer Paint/Anisotropic Metal) based on physical rendering principles; utilize lighting, depth of field, and caustics to create high-quality visuals;
3. Scene Building: Design display scenes tailored to product characteristics, skillfully using composition and lighting to enhance visual appeal;
4. Asset Library Development: Participate in building the JuJuBit standardized model library and contribute to establishing reusable, high-quality asset specifications 你将负责 1、模型精修：对商品模型进行拓扑优化、UV修复与细节增强，确保资产质量达到照片级渲染标准； 2、材质灯光调优：基于物理渲染原理，精准还原复杂材质（次表面散射/多层漆面/各向异性金属），通过灯光布局、景深与焦散营造高级感画面； 3、场景构建：根据商品特性设计展示场景，灵活运用构图与光影提升视觉表现力； 4、资产库搭建：参与JuJuBit标准化模型库建设，制定可复用的高品质资产规范。

Technical Skills

1. Proficient in Cinema 4D or Blender, with expertise in Octane or Redshift renderers;
2. Deep understanding of physical material properties, capable of independently fine-tuning complex textures (e.g., SSS for candles, clear coat for car paint, anisotropy for brushed metal);
3. Solid skills in lighting and composition, adept at using techniques like caustics and depth of field to enhance visual quality. 专业能力 1、熟练使用 Cinema 4D 或 Blender，精通 Octane 或 Redshift 渲染器； 2、深刻理解物理材质属性，能独立完成复杂质感调优（如蜡烛SSS、汽车清漆层、金属拉丝）； 3、具备扎实的灯光与构图能力，懂得运用焦散、景深等技术增强画面表现力；

Personal Attributes

1. Visual Perfectionism: Highly sensitive to nuances in lighting, reflections, and textures; can identify issues and knows how to fix them;
2. Aesthetic Judgment: Has a clear understanding of "high-quality visuals" and isn't satisfied with "good enough";
3. Inquisitive Mindset: Eager to explore new techniques and proactively optimize workflows;
4. Collaborative Spirit: Communicates smoothly with designers and developers, understanding both project constraints and possibilities. 综合素质 1、有视觉洁癖：对光影、反射、纹理等细节高度敏感，能发现问题并有方法修正； 2、有审美判断：对“高级感”有清晰理解，不满足于“差不多就行”； 3、有钻研精神：愿意探索新技术，主动优化工作流程； 4、有协作意识：能与设计师、开发顺畅沟通，理解落地限制与可能性。

Nice to Have

1. Familiarity with Substance Painter or Marmoset Toolbag;
2. Portfolio includes photorealistic still lifes or commercial product renders;
3. Knowledge of real-time rendering engine material systems (e.g., Unity, Unreal) Portfolio Suggestions. 加分项 1、熟悉 Substance Painter 或 Marmoset Toolbag； 2、有写实静帧或商业产品渲染作品； 3、了解 Unity、Unreal 等实时渲染引擎的材质系统。
