Haggi,

that is interesting because the AIR manual, on page 31, shows a very
blocky image of a scene rendered with a shading rate of 4. Maybe Scott
needs to update his manual if the renderer's behaviour/algorithm used
has changed here. :)

Well, 100 is still a u-poly edge length of 'only' 10 pixels. Pretty
close to what the Maya 'renderer' calls "production quality". ;)

> That would mean shading rate in AIR is a multiplicator for pixel
samples?

Well, since you say shading rate has not the effect any more in AIR
that is decribved in the manual, I'm frankly not sure. I guess only
Scotte himself can shed some light on this. :)

Cheers,
