Mel To Increment Render Version In Render Settings

[paulgobble]

I am modeling at still image (as opposed to an animation). In a typical fashion, i work a little on the scene, render, evaluate, repeat as needed. So I am attempting to put a little MEL script in the Render Settings > Pre Render MEL box that will auto increment the Version Label before each render.

Here is the code

[codebox]int $i;
$i = (getAttr("defaultRenderGlobals.renderVersion"));
setAttr -type "string" defaultRenderGlobals.renderVersion ($i + 1);[/codebox]

Super simple. And it kinda works. If the Version Label is set to 1 before I render, the value is incremented to 2 and I get the desired file name ( ie "render_image-2.psd"), but when I check the render settings after the render the value in the Render Settings > Version Label field has not changed. In this scenario, it is still 1. If I render again, I get the same results as the previous render ( ie "render_image-2.psd").

It works, but it doesn't.

Any idea why?

I'm running Maya 2009 on a Mac.

Thanks,
Paul

Do you call batch render? If so batch render is a spearate maya process whet gets done there never echoes back to the file your working on because theya re separate form each other.

Change what the button you use to call render does instead.
