Automatically detect frame already render.

[bigbossfr]

Hello,
Excuse for my bag english.

I know if i render my scene in MayaSoftware, there is a flag called "-rep 0" (in a .bat file) wild not calculate the images if it is already calculate.

But when i write this flag : "-r mr" for calculate my sequence with MentalRay, the flag "-rep 0" doesn't work.

How can i do ?
Called a prerender mel ?

My .bat render all frame and it is bad because i have a lot of frame already render with other PC (in LAN).

execute: render -r mr -help - is there anything listed there that might help? (I'm not at a machine with a Maya installation ATM)

Don't know what to tell you man, i've looked and looked, to my knowledge it's just not there. You can make it render in odd numbers, even numbers, things like that. But to my knowledge no autodetect.

Lame I know. :(
