Because the GI is still calculated (yes I understand that can be turned off).
And the AA settings are going to be excessive and take longer than the very basic settings the script uses.
We're still going to be rendering reflections/refractions from a vray sky which will add time.
edit: the script actually uses the scene's AA settings so disregard that.
Doing a test on a real world production scene using vrays default AA settings.
- The script takes around 15 seconds to render a mask.
vs.
Switching off lights in global switches and after 3 minutes because the vray is quoting me a 15 hour render-time. I'm not even going to bother letting it run.
Switching off lights, GI, glossy effects, shadows, and disabling the env. map and we're still looking at a 10 minute render from what the VFB is saying. I would still consider that a useless way of masking for my purposes.
