With Bucket rendering, an additional .vrimg file is written, storing the data of the completed buckets. When resuming the render, V-Ray reads the .vrimg file to determine which buckets still need to be rendered and continues to calculate what is left to complete the image. Another great ability of this feature is that the Light Cache data is saved within the partial image file so that the light cache does not need to be recalculated when the render resumes.

  • Light Cache data is saved in the resumable files, but the Irradiance Map (or any other GI map) is not, and will need to be recalculated when resuming the render. The rendering should still continue from where it was stopped, after the GI data is recalculated.
  • Enable the Resumable Rendering option before starting a new render, not only when resuming.
  • To start a new render, the old .vrimg/.vrprog resumable rendering file should be deleted.
  • The scene should not be changed between stopping and resuming, except for the Progressive sampling options (Min Subdivs, Max Subdivs, Max. Render Time in Min, Noise threshold, Ray Bundle Size).
  • When Test Resolution is enabled, Resumable Rendering is temporarily disabled.
