This page provides information about the V-Ray Frame Buffer settings.

 

Overview


The V-Ray Frame Buffer offers options to configure the Render View, Render Region, History and Layers options. The settings mainly control visibility, location of stored renders and presets, amount of disk space to use and navigating within the VFB.

 

New VFB is available in 3ds Max 2018 or later. Older 3ds Max versions only support the previous V-Ray VFB.

 

Buttons

The Render View tab controls zooming, panning and comparing of rendered images. Some of the options are available only when Show Advanced Settings is enabled.

Zoom

Zoom Multiplier – Multiplies the zoom for one mouse click.

Outside Margin – The fraction of the displayed region allowed to be outside of the displayed image. Useful when panning the image while zoomed in.

Compare

Compare Fit Mode – Specifies how to fit the compared images when their resolutions are not the same. You can choose between HorizontalVertical and Center.

Split Hit Tolerance – Specifies a number of pixels around the split lines when deciding they are close enough to be dragged with the mouse.

Center zoom on Split Line – When enabled, zooming in/out, while in history compare mode, is centered around the split position(s).

White – All bucket outlines, names of DR render servers and local rendering machine are in white.
Black – All bucket outlines, names of DR render servers and local rendering machine are in black.
None – No bucket outlines and markings are displayed during rendering.

Resize VFB on Resolution Change – When enabled, loading an image from history or new render start also resizes the VFB to fit.
