RNDRSThe Lumion alternative that runs anywhere
Lumion makes beautiful images β if you have the GPU, the Windows machine, the asset libraries and the time to set scenes. RNDRS gets to a photoreal image from a plain viewport export in seconds, in the browser, on whatever machine you already own.

Choose RNDRS when speed decides
Concept options before tomorrow's review, three facade materials side by side, a photoreal image from a model that isn't 'render-ready' β these are RNDRS jobs. No scene prep, no asset placement.
Keep Lumion when control decides
If you need a 3-minute walkthrough film with exact asset placement and physically simulated weather, a real-time engine still earns its seat. Many practices run both.
The hardware math
A Lumion seat implies a workstation-class GPU per user. RNDRS runs on MacBooks, old ThinkPads and iPads alike β the rendering hardware is ours, not yours.

Frequently asked questions
Is RNDRS a direct replacement for Lumion?
For stills β concept images, option studies, client presentation images β yes, and it's far faster. For long-form real-time walkthroughs with exact asset control, Lumion still has a role.
Do I need to import my 3D model into RNDRS?
No β RNDRS works from viewport exports and screenshots, so any software that can export an image works, with zero compatibility issues.
Does RNDRS run on Mac?
Yes β RNDRS is browser-based and platform-independent. Lumion requires Windows and a powerful dedicated GPU.
How does pricing compare?
RNDRS starts at $29/month with 3 free renders at signup, versus Lumion's per-seat annual subscription that typically costs many times that β before counting the workstation hardware.
