Shadowmatte issues - canno't see the entire shadow

[mimmio89]

Hi there, 

I'm trying to cast a shadow on a plane and on some pebbles.

On the plane everything ok, but on the pebbles I can cast only the faces looking  towards the light, the back part of the pebbles doesn't caught any shadows.. I've tryed to on off the shelf shadows, the cast shadows too but nothing..

Im using arnold and maya

Thanks in advance

Are you using the shadow matte shader or the AOV? 

Also do you have pictures of the issue.

Thanks for the quick reply, I'm using the shader, anyway I've solved the problem.

In the shadowmatte shader you have to put the backlight to 1.
