MEL script for Multi-region rendering?

[Anonymous]

Hi all,

Need help with what should be a fairly simple MEL script.

What i am trying to do

Create a script that can be called via command line (-preRender xxx.mel)
Script needs to define 9 regions of the frame and render

I know you can region render via command line using the "-reg xx xx xx xx" command, but this only renders one region per frame. I need 9 regions on the same frame.

So frame 1 has only 9 small regions of it rendered.

Any idea how to do this?

I have been looking and tryin to figure things out so far...

This is what i got


This will render a two regions in the GUI (by executing code from scriptEditor only)!

setAttr defaultRenderGlobals.left 300;
setAttr defaultRenderGlobals.rght 576;
setAttr defaultRenderGlobals.bot 75;
setAttr defaultRenderGlobals.top 530;

renderWindowRenderRegion renderView;

setAttr defaultRenderGlobals.left 754;
setAttr defaultRenderGlobals.rght 888;
setAttr defaultRenderGlobals.bot 212;
setAttr defaultRenderGlobals.top 662;

renderWindowRenderRegion renderView;

But now if i take that code and put it into a proc...

global proc renderA()
{
//Procedure...
}

Then add the "renderA;" into Maya's Pre Render, it causes Maya to crash. EVERYTIME.

What am i doing wrong/missing to get this to work sucessfully as a MEL script that can be run from command line?

Any help is appreciated.
