Save all image channels to single file Saves the image to a single multi-channel EXR or .vrimg file.

Load image – Opens an image file to be previewed in the V-Ray Frame Buffer.

Batch image processing – Allows processing of multiple .vrimg files with the same layer tree changes at the same time.

Upload image to Chaos Collaboration – Uploads an image to Chaos Cloud Collaboration for sharing and commenting.


UI Text Box

The .exr files can also be processed with V-Ray 6 Beta.
Note that deep .exr files are not supported in VFB and will be skipped if selected for processing.

Save all image channels to separate files options

Save VFB color corrections to render elements – When enabled, all color corrections are saved to the render channels (as opposed to only the RGB and effectsResult channels).

Batch Image Processing

Input folder – Specifies a path to start images.

Output folder – Specifies a path for the output images.

Layer preset – Specifies a layer tree corrections preset.

Output filenames suffix – Specifies a suffix added to the output image filenames.

Overwrite existing – Enables overwrite of existing files with the same name in the output folder.


Start interactive rendering – Starts IPR.

Abort rendering Stops the current rendering.

Render Starts rendering.

IPR Debug Shading – Enables the Debug shading/Isolate selected options in IPR. The submenu gives access to the following 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.


Follow mouseRenders 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.

Follow mouseDrag the mouse over the VFB while rendering to change what part of the image is sampled first;
Follow mouse (locked) – Locks the bucket (or sampling) starting point.

Copy current channel to clipboard – Copies the current channel to the clipboard.

Duplicate to host frame bufferCreates a 3ds Max virtual frame buffer copy of the current VFB. 

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


Display color space – Specifies the color space, in which the image is displayed.

None – Does not specify a color space;
sRGB – Displays the image in sRGB color space;
OCIO – Displays the image in a color space loaded from an OCIO configuration file;
ICCDisplays the image in a color space loaded from an ICC configuration file;
Gamma 2.2Displays the image in Gamma 2.2 color space.

Zoom VFB – Zooms in/out the rendered image in the VFB.

Zoom 50% – Zooms out to 50%;
Zoom 100% – Zooms to 100%. Alternatively, double-click in the VFB with the left mouse button;
Zoom 150% – Zooms in to 150%;
Zoom to fit – Zooms the current image to fit in the VFB. If Render Region is active – zooms to the region.

Channels – Chooses which channels to see.

View red channel – Displays the red channel;
View green channelDisplays the green channel;
View blue channelDisplays the blue channel;
Switch to alpha channel – Displays the alpha channel;
Monochromatic mode – Displays the image in monochromatic mode.

Test resolutionEnables test resolution in VFB. The submenu allows choosing a percentage of the render resolution to set as the test resolution. You can choose between 10%, 25%, 50%, 75%, 110%, 125% and 150%. 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.

Color clamping – Opens the color clamping submenu options:

Force color clamping – Forces color clamping;
View clamped colors – Displays the clamped colors.

Use pixel aspect – Enables visualization of the pixel aspect ratio.

Flip horizontally– Mirrors the image horizontally.

Flip vertically – Mirrors the image vertically.

Panorama View – Shows the image in 360° view.

Show History – Shows the History panel.

Show Layers – Shows the Layers panel.
