Behind the extraordinary rendering performance is the incredible computing power — over 30,000 physical servers. Renderbus provides users with both Web and Desktop Client, rendering 40 million frames per month and outputting more than 30TB of data per day.

Status quo

Before rendering, the user should upload the files from 3D computer graphics software such as Maya, 3ds Max, Cinema 4D, Blender, V-Ray, etc. After rendering is finished, it also needs to manually download the file. Due to the large size of the project files, users face some problems:

  • Slow upload and download speed
  • If the upload is paused or fails, the user needs to start transferring the file from the beginning
  • How to ensure file security during transfer?
  • Renderbus has users in more than 50 countries and regions around the world. How to ensure the file transfer quality in a high-latency environment?
