Region render VFB and maxscript

Hi, I’m trying to find out through maxscript if the VrayFramebuffer is going to render a region or not.

It’s quite irritating to start a rendering job only to realise that the whole thing needs to be rerendered because the region option was activated. :´(

The following commands should give me what I want but the value they hold doesn’t seem to do anything.

vr = renderers.current
vr.output_renderType
vr.output_regxmin

Even if I have region activated then the output_rendertype is still 0 and nothing I do changes that, it seems.
output_regxmin is always 0 too.., quite frustrating.

Thanks in advance!

It’d be worth downloading deadline by frantic films - they’ve a lot of great flight checks before submitting a render. It’s all maxscript too so you could have a look through their script mcr - ask bobo up on cgtalk too!
