This tab of the Render Settings holds common options for outputting files, like renders or textures. It also allows for MEL and Python scripts to be executed during the rendering process. For information about using Python with this feature, see the Python Access to the Translated V-Ray Scene page.
The Common tab also provides access the following windows:
Fancy Bullets

circle
Image Format Options - Additional settings for the selected output image format. Includes settings like quality and compression.
Ptex Baking Options - Additional settings for when the texture Baking engine is set to Ptex Baking.

File Name Prefix – Specifies the file name of the rendered image and allows adding any prefixes or suffixes to it, including some special keywords. You can add predefined keywords by right-clicking in this field and choosing from the available options. For more information, see the File Name Prefix example below.
Note: New scenes saved with V-Ray will rely on users to specify the render layer keyword <Layer> when saving with an absolute path. If it is not explicitly specified, V-Ray will warn users that files may be overwritten as a result. Older V-Ray scenes rendering with an absolute path will warn users that they use a deprecated method of handling render layers where new folders are implicitly created for each render layer. To remove this warning, run the command vrayUpgradeToExplicitLayerToken(). This will update the file to the current method of handling render layers and automatically add the _<Layer> keyword to the file name.
Version label – – Entered text will be used to replace the <Version> keyword in the File Name Prefix field.
Image Format – – Specifies the file format in which the image(s) will be saved.
Don't save image (ignored in batch mode) – When enabled, the final image will not be saved automatically.
Output alpha channel to a separate file – When enabled, the alpha channel of the rendered image will be saved to a separate file.
Don't save Alpha channel – When enabled, the Alpha channels will not be saved (ignored with multichannel exr and vrimg).
Don't save RGB channel – When enabled, the RGB channels will not be saved (ignored with multichannel exr and vrimg).
Save VFB color corrections to render elements - when enabled, allows the application of color corrections on auto-saved exports (vray/maya batch/std). Note that this option does not apply the color correction to the export when saving manually. To do so, another option can be used in the VFB > File > Save VFB color corrections to render elements. Visit the V-Ray Frame Buffer page for more information.
Resumable rendering – If there is a resumable file existing for the current frame, the rendering will be resumed from it. Otherwise a new render will be started and resumable files will be saved. If the rendering is already complete, the frame will be skipped and the next one (if any) will be started. For more information on resumable rendering, see the Continue a render with Resumable Rendering tutorial.
Note: Resumable information is stored in additional .vrimg or .vrprog files if the output file location has not changed. Resuming a render with bucket sampling will use and create additional .vrimg files. Resuming a render with progressive sampling will use and create separate .vrprog (progressive resumable) files. For instance, if resumable rendering is enabled when rendering to a PNG file format using the progressive sampler, resumable information will be saved as a .vrprog file along with the output PNG.
Autosave interval (min) – Specifies an interval in minutes for saving resumable files during rendering. This parameter applies only toProgressive sampling. A value of 0 disables autosaving during rendering and resumable files will be saved only at the end of the rendering.
Always write frame number – When enabled, writes the frame number of each output file, even if a single frame is rendered.
Convert image to sRBG for RenderView – When enabled, V-Ray will automatically convert the image to the sRGB color space in the Maya Render View window.
Clear Frame Buffers – Clears the V-Ray VFB and Maya Render View render buffers before rendering.
Use V-Ray VFB – When enabled, V-Ray will render the image in the V-Ray VFB.
Memory frame buffer – When the image is saved as either .vrimg or multichannel .exr the the information is written bucket by bucket directly on the hard drive. This specifies how V-Ray will utilize the Virtual Frame Buffer in order to optimize memory usage.
None – V-Ray doesn't display the image in the VFB in order to minimize memory usage. Full – The full image is displayed - no memory optimization. Preview – A lower resolution version of the rendered output is shown in the VFB to minimize memory usage.
Hide Render View – When enabled, the default Maya render view will not be displayed.
Hide V-Ray VFB in batch mode – Disables the Virtual frame buffer in batch rendering mode.
Disable region for batch and Chaos Cloud – Disables the region rendering in batch rendering mode and for Chaos Cloud.
Sync VFB and Maya Color Management – When enabled, it synchronizes the OCIO settings between VFB Display Correction and Maya Color Management Preferences.
Show V-Ray VFB – Opens the V-Ray VFB window.
Reset V-Ray VFB – Resets the VFB settings and position.
UI Text Box

info
This works only after the scene is reopened in a fresh Maya session before rendering or opening the VFB. This will reset all VFB settings for color corrections and others that were saved with the scene.
