Best Render Farm for Corona and 3ds Max: Fastest CPU Farm for Architecture
The fastest render farms for Corona + 3ds Max architecture are RebusFarm and GarageFarm — both SaaS farms that distribute Corona’s CPU rendering across multiple nodes simultaneously. A 4K interior still that takes 30–75 minutes on iRender’s single server finishes in 5–15 minutes on RebusFarm by spreading the work across 4–8 CPU nodes. For batch rendering (10+ images), the speed advantage is even more dramatic: 20–45 minutes total on SaaS vs 5–12 hours on iRender. Corona licensing is included in SaaS per-frame pricing — no separate license needed. iRender remains useful only for interactive Corona IR sessions and scene setup.
| Render Farm | Corona + 3ds Max | 4K Still Time | 10-Image Batch | Licensing |
| RebusFarm ⭐ | ✅ Full support | 5–15 min (multi-node) | 20–45 min | Included |
| GarageFarm ⭐ | ✅ Full support | 6–18 min (multi-node) | 25–50 min | Included |
| Fox Renderfarm | ✅ Full support | 8–20 min (multi-node) | 30–60 min | Included |
| iRender | ⚠️ CPU only (GPU unused) | 30–75 min (single server) | 5–12 hours | Separate ($350/yr) |
Why Are SaaS Farms So Much Faster for Corona Than iRender?
Corona is CPU-only — it cannot use iRender’s RTX 4090 GPU. On iRender, Corona renders sequentially on a single Threadripper Pro CPU (64 cores). One image at a time. On RebusFarm, the same image is split across 4–8 separate CPU machines, each contributing its cores to the render. Corona’s distributed rendering protocol (built into 3ds Max) coordinates these nodes automatically.
For batch rendering, the gap widens further. On iRender, 10 images render one after another: 10 × 30 min = 5 hours. On RebusFarm, all 10 images render simultaneously on different nodes: total time = approximately the time of 1 single image plus network overhead. This fundamental parallelism makes SaaS farms the natural home for Corona production rendering.
When Does iRender Still Make Sense for Corona + 3ds Max?
iRender is valuable for Corona users in two scenarios: (1) Interactive design sessions — Corona IR (Interactive Rendering) requires a live desktop connection. SaaS farms don’t offer this. On iRender, you tweak materials and lighting with real-time Corona IR preview, then submit final renders to a SaaS farm. (2) Multi-renderer workflows — studios using both Corona and Enscape (or V-Ray GPU) benefit from iRender’s RTX 4090 for the GPU-dependent tools, while Corona uses the CPU on the same server.
The practical hybrid workflow: design iteration on iRender during the day (Corona IR + Enscape preview at $8.20/hour), then submit overnight batch renders to RebusFarm (Corona final images at per-frame pricing). This maximizes both speed and cost efficiency.

Frequently Asked Questions
- Does RebusFarm support all 3ds Max plugins used with Corona?
RebusFarm supports most major 3ds Max plugins commonly used in arch-viz: Forest Pack, RailClone, MultiScatter, PhoenixFD, and Tyflow. Their automatic scene checker identifies missing plugins or textures before rendering starts. For niche or custom plugins, check RebusFarm’s compatibility list or submit a test render first. GarageFarm offers similar plugin support with a slightly smaller compatibility list.
2. How much does a 20-image Corona arch-viz batch cost on RebusFarm?
Approximately $30–90 depending on scene complexity, resolution, and quality settings. RebusFarm uses OBh (Octane Bench hours) credits — complex exteriors with dense vegetation cost more per frame than simple interiors. Total render time: approximately 25–60 minutes for all 20 images (parallel processing). The same batch on iRender (single CPU, sequential) takes approximately 10–25 hours at $82–205. For batch rendering, SaaS is 50–70% cheaper.
3. Can I render Corona scenes from 3ds Max on GarageFarm without installing anything?
Almost. GarageFarm requires a small desktop plugin to package and upload your 3ds Max scene. Once installed (2 minutes), the plugin automatically collects all scene files, textures, and assets, then uploads them to GarageFarm’s servers. No 3ds Max or Corona license installation needed on the farm — both are included. RebusFarm uses a similar plugin-based submission process. The upload plugin is the only local installation required.
