Rendered Frame Window and MAXScript
The Rendered Frame Window (a.k.a. Virtual Frame Buffer or VFB) provides Iterative and Production rendering workflows in 3ds Max 2009 and higher.
The renderer-specific extensions have been implemented using MAXScript.This means
that the controls exposed to the top and bottom panel of the Rendered Frame Window
can be enhanced or replaced by technical artists and technical directors to facilitate
various workflows and 3 rd party renderers using only MAXScript.
The following MAXScript additions provide ways to access the Rendered Frame Window
and its properties and register new rollouts in its panels:
Image Viewer DisplayNotifications
Two new notifications have been added to the General Event Callbacks mechanism: #preImageViewerDisplay and #postImageViewerDisplay
They are broadcast before and after the Rendered Frame Windows has been opened.
Interface:IVFB
The callbacks.notificationParam() method, if executed within the callback script, will return an IVFB Interface which provides the properties and methods exposed by the Rendered Frame Window.
EXAMPLE
|
The following example REMOVES the original callbacks defined in the file ..\StdPlugs\StdScripts\VFB_Methods.ms and defines new rollouts for the rollout panels.
In order to restore the original functionality, evaluate the callbacks.removeScripts #preImageViewerDisplay
then run the above-mentioned script to register the original callbacks. Alternatively, simply restart 3ds Max.
