I am currently developing a low cost render farm with Grid K520 graphics cards from nvidia.
The system is still in alpha and I require some testers. Up to now 11 users have tested the farm and left a positive feedback on the workflow / service.
This service includes the ability to render stills, animations, textures (baking) across multiple slaves at once in either Blender Internal or Cycles. Usual cost is at 65 cents USD ($0.65) by slave per hour.
If you are willing to help test the service, please send me a PM and I’ll answer back as soon as possible.
Thank you and happy blending,
Render farm is on invite only, make sure to send me a PM to get a code to signup
