mmre + displacement

[max montana]

another mmre problem which occures to me quite often: i don`t get correct masks for objects with displacement. the mask seems only to take care of the object without displacement.
what can i do?

You can probably use the material ID option instead.

thanks for the reply vlado, i`ll try that, but i am not too optimistc as i tried to get masks with the matid-re before i discovered the mmre, and never got this black-white matte masks i was looking for with the matid-re.

I meant the material ID option in the multimatte render element, not the material ID render element as such.

the material id option in the mmre i have checked. i get correct masks for all materials where i define mad id`s, but not for those with displacement.
is there a problem with mmre + displacement or am i missing something?

Seems to work for me in SP2 for a simple test (see attachments); I'm not sure why it does not work for you, but if you have a scene, you can send it to vray@chaosgroup.com so that we can take a look.
