Can I check scene is rendering?

[icapathos]

As I write in title, I hope to determine a scene is rendering or not.

I run some kind of monitoring tool within maya,

during running that it has to avoid the situation like file io.

I can check the condition with MFile::isReadingFile and so on.

But, in case of rendering I can not find the solution.

Is there any way to see the scene is rendering regardless of renderer?

Hi,

You can use preRenderMel/postRenderMel in renderGlobals.

e.g.

setAttr -type "string" defaultRenderGlobals.preRenderMel "print(\"prerender\");";
setAttr -type "string" defaultRenderGlobals.postRenderMel "print(\"postrender\");";

Yours,
