Ray traced shadows

[Axeface]

Hi there,
just a simple question here. Im using ray traced shadow in max, mental ray. However I cant seem to find the option to make the shadows smooth, obviously with shadow maps I used the map size control. How do i make them smooth with rt shadows?

Cheers

There's no way I know of making Raytraced shadows smoother.
You should use Adv. Raytraced shadows, where you can mess with shadow integrity for this sort of result, but then, Adv. Raytraced shadows are not supported by Mental Ray: error: Shadow generator "Adv. Ray Traced" on light "Omni01" is unsupported (mental ray only supports raytraced and shadow maps) ; Same applies for Area Lights. So I guess if you want smoothed shadows with Mental Ray, you're stuck with Shadow Maps.
