Matte Object - Aliased Noisy Shadows

[pixela]

Hello,
I have an matte object- VrayMaterial Wrapper.
Alpha Contribution is -1 and the shadows are checked. But the shadows are very noisy and aliased.

Any way to work this around?

Can you show an image (along with the alpha channel)?

Best regards,
Vlado

Strange but I think aliased part is not the shadows but the non-shadow areas.
I am sending you 4 partial renders:
- with matte shadow
- with matte shadow- alpha channel
- with matte material without shadows
- without any matte material

Thanks
