worn edges with AO

(1/1)

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.
https://forum.corona-renderer.com/index.php?topic=40773.msg216113#msg216113

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 ;)
