The vray vfbControl commands are supported in batch rendering mode.
VFB commands are designed to work with MEL scripting. To use them with Python, the MEL script should be wrapped in Python using the maya.cmds module.
Example of vray vfbControl in Python:
- Selects the fourth image in the VFB history and loads it into the VFB:
| Code Block | ||
|---|---|---|
| ||
import maya.cmds as cmds
cmds.vray('vfbControl', '-historyselect', 4, '-historyload') |
2. Loads an OCIO configuration file in the VFB:
| Code Block | ||
|---|---|---|
| ||
import maya.cmds as cmds
cmds.vray('vfbControl', '-loadocio', 'C:\\path\\config.ocio') |
From MEL script

The vray vfbControl command modifies the various aspects of the VFB. Commands follow the following structure:
