This page explains what Resumable rendering is and how to use it.

Overview

...

Resumable rendering is the ability to have incomplete renders resume where they left off from the previous session. The rendering might have stopped because of external forces, such as a power failure or having the job bumped on a render farm, or when you stopped the render manually and wanted to start from where you left off later.

For details on the resumable rendering parameters, please see the Render Output page.

How it works

...

Resumable renders are possible with both Bucket and Progressive image sampling modes.

...

If V-Ray finds a .vrprog file or partially completed .vrimg file for the current frame, the rendering resumes from where it left off. If not, V-Ray starts a new render and a resumable file is saved.

Workflow

...

Set the File Path from Settings > Render Output > Save Image. Any of the available File Types can be used: .png, .bmp, .tga, .hdr, .sgi, .jpg, .exr, .pic, .tiff, and .vrimg.

Note that the Resumable Rendering feature is available only after you set the output file path.

Before starting to render, enable Resumable Rendering from Settings > Render Output > Resumable Rendering. If using the Progressive sampler, it is highly recommended to enable the Autosave Interval by setting it higher than 0. This saves partial files that can be used and helps prevent losing the render progress if SketchUp crashes and a .vrprog file was not created/updated.

Start rendering your image. The passes calculate for a Progressive render or the buckets begin to drop for a Bucket render. Stop the render at any point in time. V-Ray uses the .vrimg or .vrprog files to resume the render later.
