worn edges with AO

[Edmund]

So I'm hoping to do something like this: https://www.youtube.com/watch?v=zSuhHlqabGA&ab_channel=Maxon but using Corona renderer.

So far I haven't found any way to do it, even trying this: (https://docs.chaos.com/display/CRC4D/Corona+AO) from the Corona Website doesn't seem to be as good.

I was wondering if anyone had any tutorials or docs they could share? I'm particularly interested in creating nicely worn and scratched edges, even chipped.

I know the new Corona Renderer has curvature, but it doesn't give the desired result like in the video posted.

Thanks in advance.

Following this for curvature:

or this:

AO doesn't work? It should, I saw nothing in the video you shared that couldn't be done :)

Also note, the link your are referring to is more about technical information, not so much as a ''how to''. If you would like something like that, please see this article:

Hey,

I know this is a prettey old topic. But I still haven't found a good solution to this.
I'm trying to do worn concrete edges (displacement) like in this 3dmax example. It's pretty much what I want to achieve in C4D.

After trying to utilise curvature map, ao, c4d boolean object or slicer material (the latter is killing the rendertime of course) the best restult so far I got was with distance shader to control the amount of displacement.
But i got some weird lines going on. Whats that? Am I doing something wrong or is it a bug?

And in general it's still far from the simple max example above.

Any suggestions?
Thanks ;)
