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

The New VFB is much more than a render image holder window, with Light Mix capabilities for modifying the scene project lighting after rendering and Layer Compositing for a higher level of post-processing adjustments.

  • 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:
    Add Color Corrections to rendered image and its elements;
    Layer Compositing for anything from a simple Back to Beauty workflow or advanced compositing;
    LightMix adjustment of the scene project lighting after rendering the image;
  • Scene Project editing:
    Can modify actual lights values by transferring updated intensity and color from LightMix mode;
  • Render management:
    Denoiser control;
    Region rendering control and test resolution;
    Allows you to choose the order in which the buckets are rendered.

The keyboard keys from 1 to 9 can be used to quickly load the first 9 images from the history to the VFB.

Edit note – Allows you to add a text comment to the image; the comment appears below the image.

Set A – Sets the render as A image for A/B comparison.

Set B –  Sets the render as B image for A/B comparison.

Load to VFB – Loads the selected image in the VFB (same as double-clicking on the image).

Delete – Deletes the selected image from history. The image is moved to the system's Recycle Bin and can be restored from there if needed.

Load layers – Loads the layer tree preset of the selected image.

Load V-Ray settings – Loads the V-Ray settings used for the  saved render.

Compare V-Ray settings – Opens the Compare V-Ray settings dialogue, where you can compare the render settings of saved renders.

Open scene – Opens the rendered scene project in the viewport. This option works as long as the initial file path of the scene project has not changed after the render.

Copy scene path – Copies the full path to the sceneproject.

Copy project path – Copies the full path to the project.

Reload history – Re-reads the history image list. This may be needed if the history folder is updated outside of 3ds Max (e.g. from another Revit session).
