Why Indian VFX Studios Are Building Their Own Render Farms
Cloud rendering services like Google Zync, AWS Deadline, or RenderStreet charge ₹2–₹8 per GPU-hour. A medium Indian animation studio rendering 500 GPU-hours per day spends ₹30,000–₹1,20,000 daily on cloud rendering — unsustainable for anything beyond short-term peaks. On-premise render farms pay back in 3–6 months for studios with consistent rendering workloads.
CPU Render Farm vs GPU Render Farm
The choice depends on your renderer:
- GPU renderers: Octane, Redshift, Arnold GPU, Blender Cycles (CUDA) — need NVIDIA GPUs
- CPU renderers: V-Ray CPU, Arnold CPU, Mental Ray — use CPU cores
- Hybrid: Most modern renderers support both
Recommendation for new builds in 2026: GPU render farm. GPU rendering is 5–20x faster than CPU for most production workloads, and GPU hardware costs have come down significantly.
Recommended GPU Render Node Configurations
Budget Render Node (₹3.5–₹5 lakh per node)
- GPU: 2x NVIDIA RTX 4090 (24GB each = 48GB total)
- CPU: Intel Core i9-13900K or AMD Threadripper 3955WX
- RAM: 128GB DDR5
- Storage: 2TB NVMe SSD (for OS + active project cache)
- Best for: Blender Cycles, DaVinci Resolve, short animation projects
Professional Render Node (₹8–₹12 lakh per node)
- GPU: 2x NVIDIA RTX A6000 (48GB each = 96GB total)
- CPU: Intel Xeon W-3375 or AMD Threadripper Pro 5965WX
- RAM: 256GB DDR4 ECC
- Storage: 4TB NVMe RAID
- Best for: Film-quality VFX, large scene rendering, Redshift/Octane production
Server-Based Render Node (₹4–₹6 lakh per node — best for farms)
- Base: Certified refurbished Dell PowerEdge R740 (from Serverwale)
- GPU: 2x RTX A5000 (24GB ECC each)
- RAM: 128GB DDR4 ECC
- Advantage: Rack-mountable — fits 10+ nodes in a 42U rack
Render Farm Software
- Deadline (Thinkbox/AWS): Industry standard. Free for up to 2 render nodes (Deadline Free Tier). Paid for larger farms.
- Qube!: Popular in Indian post-production studios
- Flamenco: Open-source, Blender-native render manager
- Simple queue approach: For smaller farms, a bash script with a job queue suffices
Networking for Render Farms
Render nodes pull large scene files from a central NAS. Use 10GbE minimum — a 50GB Blender scene file at 1GbE takes 400 seconds. At 10GbE: 40 seconds. At 25GbE: 16 seconds. The faster your network, the less time nodes spend waiting for data.
10-Node Render Farm Budget (India 2026)
| Component | Cost |
|---|---|
| 10x Render nodes (RTX A5000 x2 each) | ₹60,00,000 |
| NAS (100TB usable) | ₹8,00,000 |
| 10GbE switch (24-port) | ₹80,000 |
| UPS (20kVA) | ₹4,00,000 |
| Racks + cooling | ₹3,00,000 |
| Total | ₹75,80,000 |
Comparable cloud rendering at 500 GPU-hours/day: ₹30,000–₹60,000 daily → payback in 4–7 months.
