Object Mask

Hi,

I am trying to get mask of objects in scene but from 3 object buffers its showing only mask.

3 object buffer enabled, in multipass, mask, object gbuf id is checked with 3 and dragged objects in include area. something wrong in that…?
and maximum mask are 8 or more I can add…?

Thanks.

You need to add 3 masks inputs in corona multipass for each object buffer, see screenshot

Thanks.
