Scripting the Vray Frame Buffer via ME or Python ("Display colors in sRGB space")

[stwagstaff]

I'm attempting to write a short script to automatically set up correct linear workflow in Vray. So far, I have discovered no way to modify the Vray Frame Buffer by scripting. At the moment, I need to toggle on "Display colors in sRGB space". However, doing this returns no commands in the script editor, and I can't find any documentation of a way to modify this via script. Any suggestions?

Thanks

Hi,

The sRGB option in VFB will be ON by default, for the future V-Ray for Maya releases.

The latest nightly builds also support "vray vfbControl" command that allows you to control many aspects of the VFB. Type

vray vfbControl;

in the MEL script editor to see all the options - should be something like this:

vray vfbControl;
// Usage: vray vfbControl [help|-help] [-rgb|-red|-green|-blue|-alpha|-mono|-trackmouse|-linkpdp <BOOLEAN>]
                          [-swapab <BOOLEAN>] [-setcompareab h|hor|horizontal|v|ver|vertical]
                          [-loadimage|-saveimage|-saveallimage <FILENAME STRING>]
                          [-setregion <left top right bottom>]
                          [-setregion reset] To reset/disable region.
                          [-clearimage|-duplicate]

                          [-getchannelnames] Returns a string[]. Indices correspond with -get/setchannel.
                          [-getchannel] Returns the index of the current channel in string[0].
                          [-setchannel <INTEGER>]

                          For Color Corrections:
                          [-clamp|-viewclamp|-info|-history|-pixelaspect <BOOLEAN>]
                          [-levels|-curve|-exposure|-srgb|-icc|-lut <BOOLEAN>]
                          [-stereo <BOOLEAN> *or* red|cyan|1 *or* green|magenta|2]
                          [-setexposure|-setlevelsmin|-setlevelsmax <FLOAT NUM>]

                          [-loadimage|-loadlut|-loadicc|-loadcurve|-saveimage|-savecurve <FILENAME STRING>]

                          For VFB History:
                          [-history <BOOLEAN>] [-historytemppath <PATH STRING>] [-historymaxsize <INTEGER>]
                          [-historyselect <INTEGER>] To select a history image (0-based index) for the commands on the next line.
                          [-historyload|-historysave|-historyseta|-historysetb|-historyremove|-historyclear]
                          [-historycomment <STRING>]

                          For Lens Effects:
                          [-bloom|-glare|-bloomfill|-glarefill <BOOLEAN>]
                          [-bloomtype image|both|renderelem]
                          [-glaretype image|rendercam|camparams]
                          [-bloomweight|-bloomsize|-bloomshape|-glareweight|-glaresize <FLOAT NUM>]
                          [-bloomintensity|-bloomobject|-bloommaterial|-glareintensity|-glareobject|-glarematerial <BOOLEAN>]
                          [-bloomsetintensity|-glaresetintensity <FLOAT NUM>]
                          [-bloomsetobject|-bloomsetmaterial|-glaresetobject|-glaresetmaterial <INTEGER>]
                          [-glarediffraction|-glareuseobstacle|-glareblades <BOOLEAN>]
                          [-glaresetblades|-glarebladesrot|-glarefnumber <FLOAT NUM>]
                          [-glareimage|-glareobstacleimage <FILENAME STRING>]

                          For Stamps:
                          [-stamp <BOOLEAN>]
                          [-stamphalign left|center|right] [-stampvalign top|bottom]
                          [-stamptext <STRING>]

                          Where <BOOLEAN> is one of: 0|1 on|off yes|no true|false enable|disable
                                and <left top right bottom> are integers.

                          Note: Successfully loading a file or setting a numerical value
                                implicitly enables the corresponding option.
                                If you want to disable it, do it after the load/set command. //

Best regards,

Wow nice !

So in basics:

cmds.vfbControl(srgb=1)

?

Thanks, bye.

It is mel, not python.

mel.eval('vray vfbControl -srgb 1')
