Best Cloud Rendering for Lumion Exterior Scenes: Vegetation & Landscape on GPU
Lumion exterior scenes with dense vegetation are the heaviest workloads in arch-viz — and they’re exactly where a cloud GPU makes the biggest difference. A tree-filled landscape that takes 45+ minutes per frame on a local GTX 1070 drops to roughly 10–15 minutes on a cloud RTX 4090. The catch: Lumion is a single-GPU, real-time application, so only IaaS render farms work. We tested iRender (~$8.20/hr, RTX 4090, 24GB VRAM), Xesktop (~$10–14/hr), and AWS EC2 (~$12–20/hr). For vegetation-heavy exteriors, iRender gave us the best balance of raw GPU power and cost per frame.
| Cloud Option | GPU | VRAM | Exterior Scene (est.) | Price/Hour |
|---|---|---|---|---|
| iRender ⭐ | RTX 4090 | 24 GB | ~10–15 min/frame | ~$8.20 |
| Xesktop | RTX 3080/4090 | 10–24 GB | ~12–18 min/frame | ~$10–14 |
| AWS EC2 | A10G / T4 | 16–24 GB | ~15–25 min/frame | ~$12–20 |

Why Do Lumion Exterior Scenes with Vegetation Need So Much GPU Power?
Every tree, shrub, and grass patch in Lumion is a real-time 3D object loaded into VRAM. A light exterior might use 4–6 GB. A full residential landscape with hundreds of trees and ground cover? That pushes 12–18 GB of VRAM. On a local GPU with 8 GB (like an RTX 3060), Lumion starts swapping to system RAM and render times spike. An RTX 4090 with 24 GB VRAM holds everything in fast memory — that’s why cloud GPUs make the biggest difference for exterior work specifically.
How Does iRender Handle Lumion Landscape Rendering in Practice?
We uploaded a residential exterior — roughly 200 trees, mixed shrubs, and a grass terrain — to an iRender RTX 4090 server. First-time setup took about 20 minutes. After that, reconnecting was under 2 minutes.
The biggest thing to flag: the billing timer. iRender charges by the hour and it doesn’t stop when your render finishes. Kick off a batch overnight and forget to disconnect? That’s roughly ~$65 in idle charges. Set a timer on your phone.

Frequently Asked Questions
- How much VRAM does Lumion need for heavy vegetation exterior scenes?
It depends on density. A typical exterior with light landscaping uses 4–6 GB VRAM. Heavy vegetation — hundreds of trees, layered ground cover, large terrain — can push 12–18 GB. An RTX 4090 with 24 GB VRAM (like on iRender) keeps those assets in fast memory, avoiding the swapping that cripples renders on local 8 GB cards.
2. Can I use RebusFarm or GarageFarm for Lumion exterior rendering?
No. Lumion runs as a real-time, single-GPU application that requires a live desktop session. Traditional SaaS farms like RebusFarm and GarageFarm distribute renders across multiple nodes automatically — they can’t run Lumion at all. You need an IaaS render farm (remote desktop access to a dedicated GPU). The main options are iRender (~$8.20/hr), Xesktop (~$10–14/hr), and AWS EC2 (~$12–20/hr with manual setup).
3. How much does it cost to render a Lumion landscape walkthrough on the cloud?
On iRender’s RTX 4090, a 2-minute 4K walkthrough of a vegetation-heavy landscape typically takes 30–50 minutes of render time, costing around $4–7. If you’re batch-rendering multiple exterior views overnight, expect $15–35 depending on scene count and complexity. Just remember to disconnect when it’s done — the billing timer runs continuously, and an idle overnight session can add ~$65 in wasted charges.
