The V-Ray Frame Buffer (VFB) is a second generation V-Ray virtual frame buffer.

UI Text Box
typenote

VFB Cloud Collaboration is a new feature available only in V-Ray 6, for 3ds Max.

VFB Cloud Collaboration is not supported in 3ds Max 2018 and 2019.

VFB is much more than a render image holder window. The new enhanced version provides a higher level of post processing adjustments and ability to modify your scene from inside the VFB. Here is a list of old and new benefits you should know:

  • Image preview:
    Loads render elements channels via a dropdown list;
    Works with display corrections;
    Loads various 8bit and 32bit file formats, including V-Ray resumable files;
    Image comparison between 2 or 4 renders;
  • Image management:
    Keeps the rendered image in full 32-bit floating point format;
    Can store history of rendered images with their post rendering corrections;
    Can save corrected output to various image formats;
  • Image editing and post processing:
    Set Color Corrections to rendered image and its elements;
    Composite mode for Back to Beauty workflow including layers corrections;
    LightMix control on lights contribution in the rendered image;
    Applying Proportion Guides on the rendered image;
  • Scene editing:
    Can modify actual lights values by transferring updated intensity and color from LightMix mode;
    IPR camera navigation and focus control from inside VFB;
  • Denoiser control;
    Region rendering control and test resolution;
    Option to choose the order in which the buckets are rendered;
    Automatic render resolution adjustment in IPR when the VFB window is resized;
  • Collaboration:
    Shares images with other Chaos users in Chaos Cloud Rendering.

To use the VFB for rendering, turn on the Enable built-in frame buffer option in the Frame buffer rollout under the V-Ray tab in the Render Setup window.

VFB also has some limitations which are listed in the Notes section below.

VFB Menu

...

The V-Ray Frame Buffer menu holds the main frame buffer commands. Some of the options are also available in the VFB toolbar for a quick access.

...

Locks the mouse pointer coordinates and displays information for the selected pixel.

Shows corrected colors.

Shows the V-Ray Log which contains messages about the render process. The V-Ray Log is also available in the Log tab.

Displays the red channel.

Displays the green channel.

Displays the blue channel.

Displays the Alpha channel.

Saves the image to disk. Select and hold the icon to bring up the submenu:

Save current channel – Saves the current channel to an image file format;
Save all image channels to separate files – Saves all the render elements into separate files. Click the options () button to open a menu with more options.
Save all image channels to single file – Saves the image into a single multi-channel EXR or .vrimg file.
Upload image to Chaos Collaboration – Uploads an image to Chaos Cloud Collaboration for sharing and commenting.

Clears the contents of the frame buffer. This is useful when starting a new render to prevent confusion with the previous image.

Renders the closest bucket found to the mouse pointer, when using the bucket image sampler. If the progressive sampler is used, V-Ray samples the closest pixels to the mouse pointer. With this option enabled, you can right-click on the image and select Lock bucket starting point to lock the bucket (or sampling) starting point.

Enables/disables test resolution in the VFB. Select and hold to bring up the submenu to select the percentage of the render resolution to set as the test resolution. Note: This only affects V-Ray and does not affect the native 3ds Max test resolution setting found under 3ds Max's Render Setup dialog.


Renders rectangular regions in the VFB. See the Region Render section for more information.

Image Modified

Renders multiple polygonal regions in the VFB. See the Region Render section for more information.

Enables the Debug shading/Isolate selected options in IPR. Select and hold to choose between the different modes:

Isolate Selected – Renders only the selected object(s), while the rest of the scene is rendered black. You can also select material or texture nodes to isolate all objects with the assigned shader;
Isolate Locked Selection – Locks the selection to the currently selected object(s). Changes to other objects or lights can be made while rendering the same isolated object(s);
Lightning – Renders only the light contribution in the scene;
Ambient Occlusion – Renders ambient occlusion for the scene;
Wireframe – Renders the scene objects in wireframe;
Normals – Shows the normals of the scene objects;
UVs – Displays the UV coordinates of the scene objects.

Starts IPR. If there is more than one camera in the scene, hold left mouse button to display a list of the available cameras.

Cancels the current render. When the render is cancelled, the Denoiser is not applied or saved, equivalent to the behavior of the Cancel button in the Rendering window.

Image Modified

Stops the ongoing rendering at its current state. It takes the render's current state as valid to perform all post-rendering tasks such as post-effects or image output saving.

Starts rendering. If there is more than one camera in the scene, hold left mouse button to display a list of the available cameras.

When pressing Shift + this button, starts Render last and the last rendered viewport/camera is rendered.

Pauses interactive rendering when using V-Ray GPU.

Refreshes interactive rendering.

If you want to keep the layers that come with the Max scene, turn the Auto Load Layers option off from VFB > Options > History tab. If you want to load layers from an external image, enable the Auto Load Layers option and check how you save those images.

Filters

...

The redesigned V-Ray VFB provides a variety of filter presets. The Filters panel preset previews provide easy check of multiple color corrections scenarios. Applying one of the filters, adds it as a folder on top of the layer tree. On the next filter load the top preset folder in the layer tree is replaced by the new corrections. To create custom filters in the VFB Layers panel right-click on a folder containing correction layers and save it as a .vlpdir file. Change presets directory from V-Ray Frame Buffer > Options menu > VFB Settings > Filter/Layer presets > Path. Personal custom filters are now shown in the panel and can be loaded quickly.

Layers

...

The redesigned V-Ray Frame Buffer includes a suite of color corrections and tools for adjusting the image. The tools are added as layers and displayed in a layer tree. You can enable or disable a particular tool using the visibility icon (Image Added). The Frame Buffer includes a suite of color corrections and tools for adjusting the image. The tools are added as layers and displayed in a layer tree. You can enable or disable a particular tool using the visibility icon (Image Removed). The icon indicates that a layer is disabled. All layers have a vertical line marker for clear differentiation between fixed and flexible layers. Fixed layers are marked with a grey line, while newly added layers, which can be moved around freely and put into groups, are marked with a blue line.
