Explude matte objects from Z-Depth

I have some matte object I make matte using VRayMtlWrapper.

These objects show up in the ZDepth buffer, though. I would like to not see them in the depth buffer and I need to merge parts of the depth buffer into another depth buffer…

Hi,

Suppose that you want to do it at once and I think an option for Include/Exclude list for the Zdepth is required.
Zdepth pass will always use all renderable geometry objects in the scene.

An option would be ideal!

Thanks…
