Vray Standalone cmd like options

[Cruz]

I've recently been putting our Linux Farm to work sending renderings out via cmd line.
There's one this one thing I just can't seem to wrap my head around though:

How exactly do I take a .vrscene and render only lets say Frames 10-15 out of a 1-100 Frame scene?
I typed vray to get all the options printed out in terminal and tried the -frames=b0... with all the {}*[] mess.
But without really understanding why there is two numeric values for begining end and incement I was kind of lost and vray kept replying error: wrong frame number or something like that

Would help me alot instead of reexporting vrscenes from maya over and over again

You need to type -frames=10-15 that's all. In general, things in [] brackets are optional, things in {} curly braces can be repeated zero or more times.

Thanks Vlado, I will try this on the next scene.

Somehow related question: Is there a good cmd line image converting app like imagemagick, but capable of converting 32 exrs into 16 bit png's?

Like a batch conversion or something I could build a script with?

[vlado]

Hm, I can't think of one right away; we can certainly write a simple tool for that using our own code for image reading and writing.... or maybe something can be scripted with python and Maya...

And why not to give us the possibility to use the VFB in command line ?

I did some more searching and found 2 Tools that seem fit for the job and my workflow:

exrtools

and

DJV Viewer
http://djv.sourceforge.net/

Will let you know how it works out once I get to get everything running with the sysadmin
