For anyone still hitting this thread in 2025 and wishing “someone would just open a farm for Unreal projects” — that exists now.
HyperRender is a plug-and-play cloud render farm built only for Unreal Engine:
One-click from Movie Render Queue. The plugin auto-packages your level, uploads just the changed assets, and keeps everything in sync.
Dedicated A5000 / A6000 nodes per shot. True parallelism without Swarm or Python scripts.
Own bare-metal fleet, pay-as-you-go.
Typically ~70 % cheaper than the usual on-demand GPU rates, with no idle fees.
Scales to hundreds of GPUs in minutes; perfect when Lightmass, Lumen, or path-traced cinematics blow past local capacity.
Drop me a DM for a test credit if you want to benchmark it. Hope that helps the next dev who lands here looking for an Unreal-specific render farm.
