Page History

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:

UI Path: ||Render Settings window|| > Common tab

Image RemovedImage Added

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 to  Progressive sampling. A value of 0 disables autosaving during rendering and resumable files will be saved only at the end of the rendering.

Delete resumable file on success – When enabled, deletes the resumable file (either .vrimg or .vrprog) upon completion of the render.

Always write frame number – When enabled, writes the frame number of each output file, even if a single frame is rendered.

For more information, see Image Format Options.

Render – Enables V-Ray to render the image to the frame buffer and then save an image file as specified in the Common tab of the Render Settings window. This option can be used at the same time as Export to a .vrscene file.

Export to a .vrscene file – Enables V-Ray to export the scene to a .vrscene file and expands the options in the rollout.

File name – Specifies the location and name for the .vrscene file.

Separate files – When enabled, V-Ray will export separate files for different components of the scene. This also allows you to disable export for certain types of objects.

Each frame in separate file – When enabled, V-Ray will make a separate file for each rendered frame.

Strip paths – When enabled, the paths for assets (bitmap textures, proxies, GI caches loaded from file, etc.) are removed from the exported file and only the file names of the assets remain.

Write mesh data in hex format – When enabled (the default), the mesh data will be written in hexadecimal format in the .vrscene file. This makes the files smaller and faster for processing, but less readable to a user. When disabled, the mesh data will be written in normal decimal format.

Write transform data in hex format – When enabled (the default), transform data will be written in hexadecimal format in the .vrscene file. This makes the files smaller and faster for processing, but less readable to a user. When disabled, the data will be written in normal decimal format.

Compressed – When enabled, basic compression will be applied to the .vrscene file. This option can only be used together with Write mesh data in hex format.

Plugin Names Prefix – Allows the user to specify a prefix for plugin names.

Baking engine – Selects the baking engine type.

None – No additional exporting will happen during render times. 
Texture Baking – A texture will be baked for the selected object. 
Bake to vertex color set – Bakes a vertex color set.
Ptex Baking – A .ptex file will be baked for the selected object(s).

U min /V min/U max/V max – Specifies a custom layout to which the texture will be baked.

Bake channel – Determines the channel to bake. 

Edge padding (dilation) – The number of pixels to expand around geometry. 

Shoot rays from camera – When enabled, the baking engine will use rays whose direction originates from the camera. As a result, the object will be baked as seen by the camera.

Color set name – When Bake to vertex color set is selected, this specifies the name of the vertex color set.

Bake RGB color – Bakes the RGB information to the map.

Bake alpha – Bakes the Alpha information to the map.

Ptex baking options – Opens the options dialog for Ptex baking.
