Best Render Farm for V-Ray Architecture: GPU Cloud Rendering for Arch-Viz Studios
V-Ray is the only major arch-viz renderer that works on both IaaS and SaaS cloud render farms. Unlike Lumion, Enscape, Twinmotion, and D5 Render (which all require IaaS-only farms), V-Ray supports command-line rendering and multi-GPU distribution — meaning traditional SaaS farms like RebusFarm, GarageFarm, and Fox Renderfarm all support V-Ray. For GPU rendering on a single RTX 4090 at iRender (~$8.20/hour), a 4K arch-viz still takes 15–45 minutes, costing $2.00–6.00. On SaaS farms with multi-GPU distribution, the same image can render in 5–15 minutes by spreading the work across 4–8 GPUs — but at higher total cost per image.
| Render Farm | V-Ray Support | Type | GPU | Pricing Model |
| iRender ⭐ | ✅ Full (GPU+CPU) | IaaS | RTX 4090 | ~$8.20/hr |
| RebusFarm | ✅ Full (GPU+CPU) | SaaS | Multi-GPU | Per-frame |
| GarageFarm | ✅ Full (GPU+CPU) | SaaS | Multi-GPU | Per-frame |
| Xesktop | ✅ Full (GPU) | IaaS | RTX 3080/4090 | ~$10–14/hr |
Should Arch-Viz Studios Choose IaaS or SaaS Farms for V-Ray?
Choose SaaS (RebusFarm, GarageFarm) when you need to render large batches — 50+ frames for animation, 20+ stills for a project package. SaaS farms auto-distribute across multiple GPUs, completing large jobs in parallel. RebusFarm is particularly strong for V-Ray with automatic scene checking and missing texture detection — features that save hours of troubleshooting on large projects.
Choose IaaS (iRender) when you need full pipeline control — interactive material tweaking, test renders, scene adjustments between renders. On iRender you have a live desktop where you can adjust V-Ray settings, preview render regions, and iterate in real-time. The hourly pricing ($8.20/hour) is also more predictable for small batches (1–10 images) than per-frame SaaS pricing, which varies by scene complexity.
How Does V-Ray GPU Scale with Multiple GPUs on Cloud?
V-Ray GPU scales across multiple GPUs with approximately 85–95% efficiency — meaning 2× RTX 4090 renders roughly 1.8× faster, and 4× RTX 4090 renders roughly 3.4× faster. On iRender, multi-GPU servers are available: 2× RTX 4090 at ~$16/hour, 4× at ~$32/hour. The practical trade-off: multi-GPU is faster per image but costs more per hour. For a single 4K image, single GPU ($2–6) is almost always more cost-effective than 4× GPU ($4–8 for half the time). Multi-GPU is worth it only for animation and tight deadlines.

Frequently Asked Questions
- Is V-Ray GPU or V-Ray CPU better for arch-viz on a cloud render farm?
V-Ray GPU is faster for most architectural scenes — a 4K still renders in 15–45 minutes on a single RTX 4090 vs 30–90 minutes on 16-core CPU. GPU also scales across multiple cards (2×, 4×, 8×). However, V-Ray CPU handles scenes with extreme VRAM requirements (100+ million polygons) more reliably because system RAM (256GB on iRender) is not limited like GPU VRAM (24GB). For most arch-viz work, GPU is the recommended choice.
2. Do I need a separate V-Ray license for cloud rendering on iRender?
V-Ray licenses are tied to individual workstations. If you already have a V-Ray license, you can transfer it to iRender’s server by deactivating on your local machine and activating on the cloud server. Chaos (V-Ray’s developer) also offers render node licenses specifically for cloud/farm use at reduced cost. For SaaS farms (RebusFarm, GarageFarm), V-Ray licenses are typically included in the per-frame pricing — no separate license needed.
3. Which render farm is cheapest for V-Ray architecture animation (100+ frames)?
For large animation batches, SaaS farms are typically cheaper. RebusFarm and GarageFarm distribute 100+ frames across many GPUs simultaneously, completing the job in 1–3 hours regardless of frame count. On iRender (single GPU), the same 100 frames render sequentially in 25–75 hours. For animations specifically, we recommend comparing actual quotes from RebusFarm and GarageFarm against iRender’s hourly rate for your specific project.
