V-Ray Scene Optimisation Script

Actually, this is EXACTLY what is going to happen using MSR and a low min/high max rate.
MSR WILL shift the sampling towards less camera rays, and so, with high enough MSR, you WILL get worse edges (unless, of course, one sets very low thresholds globally).
Here’s two pictures of an alpha edge, see for yourself.
All to default, no image filtering.
AA 1-100, MSR of 1

You can tell there are indeed differences, as less camera rays are cast there.
Which is another reason for having a fixed AA method with a min rate which isn’t of 1, regardless of the scene contents, and high enough to have the alpha edges clean.
The sample rate element for that image also shows the same behavior: higher MSR, lower camera rays (and ofc quicker renders.).

Eeeeenteresting - must have a bit of a fiddle with it. Got a few bits with fine detail which should provide a test.
