Transparent Shadows with MR matte/shadow/reflection map

Hi,

Hope someone can help as I can't find any info on this on the net.

I'm using MR matte/shadow/reflection map as the ground plane in my product shot scene with the background set to white. Shadows from opaque objects are fine but shadows from transparent objects do not appear transparent, they are the same as the solid objects. This also applies to the ambient occlusion. I've looked through the settings and the matte/shadow/reflection map does not have the advanced settings you see in the arch/design materials.

Any help in this area would be appreciated. Thanks..............

I just created a plane with a Matte/Shadow/Reflection material assigned to it. (No settings changed) Plus a sphere with an arch design material, solid glass chosen as preset.
Everything seems normal here.

I've had problems before when exposure control is on, that's why I wanted to check, but strangely it worked seamlessly this time.

I will try doing exactly as you have done and check the result. It could be a setting I'm adding that's messing it up. By default the ambient occlusion is off so you may not have seen that particular problem. Perhaps it's the material?? I will give a go.....

thanks
