how to set the VFB-Renderregion from inside maya

[ultrasonic]

Hi Guys,

i want to do some render-optimization and therefore i would like to set a renderregion for vray while rendering in mayabatch using a pre-render-frame callback.
Can anyone please give me some advice how to "inject" that region into vray-translation process? And is it possible to adjust that region on a per frame base?

thx in advance
Oliver

You can try calling vraySetBatchDoRegion(left, right, bottom, top) - this is what the -reg command-line switch to the Maya batch command does.

sounds great! Thx!

Will this also work if i want to render frames 1-5 with a moving object where i need to set the region per frame?

I'm not sure - you'll have to try it and see what happens. If worse comes to worse, you'll have to render each frame with a separate batch command.
