Best Render Farm for Architecture: iRender vs RebusFarm
Comparing iRender to RebusFarm is like comparing a rented office to a print shop — they serve fundamentally different purposes. iRender (IaaS) gives you a remote desktop with an RTX 4090 at ~$8.20/hour — you install software, control everything interactively, and can run any application including Lumion, Enscape, Twinmotion, and D5 Render. RebusFarm (SaaS) automates V-Ray/Corona batch rendering — submit a scene, it distributes across multiple nodes, you download finished images. RebusFarm is faster and often cheaper for V-Ray batch (10 images in 20–45 min). iRender is the only option for real-time tools and interactive design work. They’re not competitors — most architecture studios that render seriously end up using both.
| Feature | iRender (IaaS) | RebusFarm (SaaS) |
|---|---|---|
| How it works | Remote desktop — you control a server | Automated — upload scene, download result |
| Lumion / Enscape / D5 / Twinmotion | ✅ All supported | ❌ Cannot run |
| V-Ray / Corona | ✅ Interactive + sequential batch | ✅ Multi-node parallel batch (faster) |
| V-Ray 10-image batch speed | 2.5–5 hours (sequential) | 20–45 min (parallel) ⭐ |
| V-Ray licensing | Your own license needed | Included in pricing ⭐ |
| Pricing model | Per hour (~$8.20/hr) | Per frame / render point |
| Billing risk | ⚠️ Timer runs until disconnect | ✅ Pay only for completed renders |
| Plugin support | ✅ Any plugin (full admin access) | ✅ Major plugins (pre-installed list) |
| Scene checking | ❌ Manual (you verify yourself) | ✅ Automatic pre-render check ⭐ |
Where iRender Wins Clearly
Real-time applications. If you use Lumion, Enscape, Twinmotion, or D5 Render — iRender is your only cloud option. Period. RebusFarm cannot run these tools. Interactive V-Ray work. Material previews, lighting adjustments, camera setup with V-Ray GPU Interactive — all require a live desktop that SaaS farms don’t provide. Custom software stacks. Niche plugins, in-house scripts, Grasshopper definitions — install whatever you need with full admin access. Multi-application sessions. Open Revit + Enscape + Photoshop simultaneously on the same server for a complete design-to-deliverable workflow in one billable session.
The Honest Verdict
If you use only real-time tools: iRender is all you need. If you use only V-Ray/Corona batch: RebusFarm is all you need. If you use both (the most common scenario for studios): use both. iRender for daytime interactive work ($8.20/hour), RebusFarm for overnight batch output (per-frame pricing). They complement each other perfectly. Monthly combined budget: approximately $150–250 for iRender + $50–150 for RebusFarm = $200–400 total for a mid-size studio handling 5–8 projects.

Frequently Asked Questions
- Can iRender match RebusFarm’s batch rendering speed?
Not on a single server — iRender renders images sequentially (one at a time). To match RebusFarm’s parallel speed, you’d need to rent 5–10 iRender servers simultaneously and split your image list across them. This is possible but more complex and typically more expensive than RebusFarm for straight batch work. iRender’s advantage is flexibility (run any software), not batch throughput.
2. Is iRender or RebusFarm cheaper for V-Ray architecture rendering?
For single images and interactive work: iRender ($1.40–4.10 per V-Ray image). For batches of 10+: RebusFarm is often 20–40% cheaper due to parallel efficiency and included licensing. The crossover point is approximately 5 images — below 5, iRender is simpler and comparable in cost. Above 5, RebusFarm’s parallel distribution makes it the better value for pure V-Ray output.
3. Should a new architect start with iRender or RebusFarm?
iRender first — it’s more versatile. You can run any renderer (Lumion, Enscape, V-Ray, anything) with full desktop control, which feels familiar to anyone who’s used a PC. RebusFarm requires uploading scene files through its submission plugin and understanding per-frame pricing — a slightly steeper learning curve for first-time users. Once comfortable with cloud rendering, add RebusFarm for V-Ray/Corona batch output. Both offer free trial credits to test.
