Hi Sylvain,
I forgot to click to send the message back to me, so I just saw this.
Sorry for the delay.
I think you're right, but for some reason it doesn't quite work.
The following works in MEL
miCreateDefaultNodes();
select -r defaultRenderGlobals;
setAttr "miDefaultOptions.minSamples" 0;
setAttr "miDefaultOptions.maxSamples" 2;
I'm not sure if I'm translating it right in python, but for some
reason the mental ray globals don't seem to enable.
This seems like a super simple translation, but maybe I'm missing
something?
