Matte object/material

[Method]

Hi,
Looks like the matte object can not receive AO. Only the shadows.

Is this true, or am I doing something wrong?

Matte object is the only solution for non-functional camera mapping. (maybe than one, but the easiest)

sorry, i can't test the matte issue with ao right now, but do you know that now octane 2.0 has an AO pass in the infochannel kernel?
maybe is enough for your needs

Matte function works perfectly with diffuse material on the plane objects.
Remains unanswered question - how to get rid of the shaded area in the pits or inside the objects, which is used to mask with mate-material?
How to get clean masked object with alpha? Can anybody help?
It would be very useful.

If I understand well you just need to delete poly from the side just keep the 2 horizontal

Or do two renders, one for each height.

Thanks for the response.
Meaning of the question is how to make a complicated mask with alpha channel for a complicated object using a matte material.
This example is a simplified version of the problem. Not for the fake solutions.
How to remove from the material properties of the response to self-shading and occlusion?
Anyone can help? Or maybe in next release?
Sincerely.
