Starting from Corona 12, the new VFB 2.0 is the new default VFB in Corona, featuring an updated interface with improved user experience. For a complete overview, refer to the official documentation.
If you prefer to use the legacy Corona VFB, you can switch to it from Corona Render Setup > System > System Settings > VFB Settings > Corona VFB.
Corona includes its own Virtual Frame Buffer (VFB) window and interface that has been tuned to the most common needs of artists and can provide a very decent post-production experience and results.
The VFB has been further improved to enhance the usefulness and number of actions that can be performed directly from the VFB itself. These are:
- The ability to pick objects directly from the VFB.
- The ability to pick a point on the surface of an object to focus the Camera to (for DOF) directly from the VFB, via right-click.
- Right-click menu in docked IR (interactive render in the viewport).

Picking objects directly from the rendered image in the VFB
To pick an object from the rendered image and have it become selected, click the "Pick" button in the VFB toolbar:
With the "Pick" button active, you can click on any object in the rendered image and that object will be selected in 3ds Max.
Picking a point on the surface of an object for determining the focal point of the camera
To set your Camera's focal point to a certain point in space (on the surface of an object), with the "Pick" button active, right click the point in the rendered image and select the "Set focus to this point":
If your Corona Camera has Depth of Field turned on and set to override with "Value" selected as the override, Corona will calculate the distance of the picked point to the camera and set this distance as the value of the Corona Camera's override value:
If the Corona Camera you are using does not have Depth of Field activated or "Override focus" is not activated, selecting a point will change the camera's "Target distance".
The right-click menu in in-line IR
In Corona 4 a right-click menu has been added to the in-line IR that contains the following functions:
-
Set focus to this point
Sets the Corona Camera focus point to the clicked point on the object. -
Copy to clipboard
