full osa button?

Hey guys. Just noticed the full osa button in the materials window. Hadn’t seen it yet. What exactly does it do???

it activates real osa for this object. I’m just guessing but it may be for stuff like having geometry that’s less than a pixel. This gave very bad result with the old osa. maybe a developer (theeth?) can explain this more precise.


thanks… forgot it was in the blender download section… :wink:
