Corona AO + Displace???

[alco3d]

Hello everyone!
Is there a way to make procedural displace on edges of object? I spent much time to achieve displace effect on edges in Vray and didn't receive a result. I try to solve this through Vertex map, AO baking and etc, but noone to work as expected, because, as I learned recently, this a extremelly hard to render.
Now I here and need you help. May be Corona and you could solve this task.

Hi,

I don't think this is possible. The main question is: why would you need something like this? :)

Generally in computer graphics, displacement happens in the direction of the geometric normal. If you have two faces at right angles to each other, there is no standard method to have displacement between the faces. Inserting a bevelled edge with a number of segments in there will help, but it all depends on your geo topology.

You could try applying a map to mask out areas you don't want to displace, but the areas that are displaced will still be in the direction of the geometric normal.

To render some unwrappable stuff.:)
Many small details which I want make older and rusted. I would be happy to implement it with bump map on egdes, but it looks so poor in Vray. A baking for vertex map is loosing small details and so silly. I have no big experience in render and on a first sight it looks so simply to displace by procedural AO map. :)

Yes, that I tried in Vray, and yes, a displace didn't see the mask AO.(((
