Simply put, Batch Render allows you to queue up several views (including different channels) from different files to render in sequence, freeing you from manually rendering each image one at a time. This tutorial will go through a brief overview of batch rendering in V-Ray for Rhino. The files for this tutorial can be located here (77 MB).
Step 1. First, save the views you wish to render using Rhinoceros’ “Named Views” panel in each file you would like to render. You can use current views, but using named views is recommended as they are not as easily modified by accident.
There are no special settings needed in the V-Ray option editor for batch render to work, but make sure that you have the Options set as you would like them for the renders in each file.
Make sure to save all Rhinoceros files you plan on rendering. If you have multiple instances of Rhinoceros running with multiple files open, make sure to close them out, so there is only one Instance of Rhinoceros open.
For this step, it is not necessary to have any of the files you will be rendering open. Go ahead and select the “Batch Render” tool in the “V-Ray Extra” toolbar.
From within the Batch Render Bar dialogue, click on the File button and select the first file you wish to render from. If you have one of the files already open, it is usually a good idea to select that file first to cut down on any extra opening and closing of files during the batch render process.
You are now presented with the dialogue to choose the views you want. Any named view will have the “NamedView-” prefix. You may either choose one view, or hold down shift to select multiple views, then select OK when you are finished.
If you plan on rendering from multiple files, click on the File button again and repeat the above steps. You may also use the View button to load more views from the previously selected file if you accidentally left any out.
By default, the rendered images will be saved as .PNG files .To select a different file format, click on the Options button.
When you are ready to go, simply click on the Start button and V-Ray will start opening the files and rendering each view in sequence.
You can monitor the progress in the Batch Render Bar as it progresses through the list.
V-Ray will save the rendered images to the same directory that the corresponding .3DM file resides in.
This concludes the Batch Rendering with Rhinoceros tutorial. Using this tool, you are now able to easily automate the process of rendering multiple views at once.
