Unit
- Pipeline stages: A CGI production pipeline consists of three main phases: pre-production, production, and post-production. Pre-production involves concept art, storyboarding, and planning. Production covers modeling, texturing, rigging, animation, lighting, and rendering. Post-production includes compositing, color grading, and final output. Each stage feeds into the next with specific deliverables.
- Asset creation workflow: Assets move from modeling to texturing to shading. Modelers create geometry, UV mappers unwrap surfaces, texture artists paint maps, and shading artists assign materials. This sequential process ensures each layer builds on the previous one without rework.
- Render engine selection: The choice of render engine affects lighting, materials, and output quality. Physically based renderers like Cycles or Arnold simulate real-world light behavior. Real-time engines like Unreal Engine prioritize speed for interactive applications. Understanding trade-offs between photorealism and performance guides engine selection.
- Data management: Version control, file naming conventions, and asset libraries prevent chaos. Using centralized storage and naming standards like
prop_chair_v001.blendensures team members find and update files without duplication. Regular backups protect against data loss. - Collaboration tools: Review platforms like Frame.io or Shotgun allow supervisors to annotate frames. Teams discuss feedback in virtual dailies sessions. Clear communication channels reduce iteration cycles and align creative vision.
- Pre-visualization: Low-res blocking tests key shots before full production. Animators place simple shapes to test timing and composition. Directors approve camera angles and motion trajectories early, saving resources on detailed assets that might be cut.
- Render farm management: Large sequences require distributed rendering across multiple machines. Render managers divide frames among nodes, monitor progress, and handle failures. Efficient farm setup reduces turnaround from days to hours.
- Final delivery: Output formats vary by use: EXR sequences for film, MP4 for web, or still frames for print. Proper color space conversion ensures consistency across displays. Delivery packages include source files, renders, and documentation.
- Rigging and skinning: Character rigging creates a digital skeleton for deformation. Riggers build joint hierarchies, controllers, and constraints to allow animators to pose characters naturally. Skinning assigns vertex weights so geometry bends correctly. Proper rigging ensures believable movement and prevents artifacts like collapsing joints. This stage is critical for organic characters and mechanical assemblies alike.
- Simulation and effects: Dynamic simulations add realism through cloth, hair, fluids, and destruction. Artists set up physics parameters and collision objects, then run simulations that generate complex motion automatically. Caching simulation data to disk allows iterative playback without recomputing each time. Combining simulated elements with keyframed animation requires careful layering and control.
- Look development: Look dev artists refine the final appearance of assets under lighting. They adjust shaders, textures, and materials to achieve a specific aesthetic, testing in representative lighting environments. This stage ensures consistency across all shots featuring the same asset. Look dev often uses iterative feedback loops with art directors to match the visual style guide.
