Hello guys,
I am trying to replicate the edges of some elements from this Rendering
https://forum.corona-renderer.com/index.php?topic=44666.0
(https://freeimage.host/i/edges.3RAM9G1)
I ve asked the creator and got this answer:
i added a chamfer and a noise modifier to the geometrie! Your Geometry needs to be subdivided enough. If your pc isnt good enouigh just use the corona round egdes map and ad a noise map into the corona round edge map. The other way to do it is in postproduction
But i still not able to get similar results, mabye or i am very sure i am doing something wrong.. can someone give me a short guidance?
I tried the option with CoronaRoundEdges, but when i Plug in "Noise" in the Radius slot nothing happens..

After a few tries with Box - Champfer - Subdivide - Noise i got this result
The second one i accomplished with the coronaroundedges and noise within radius
but still very different in my opinion

Couple suggestions how you could improve your setup to get better result. Change subdivide mode to variable curvature, it will allow you to have more finely subdivided edges without blowing up polycount. Use several noise modifiers, first one with large scale and strength and each subsequent with smaller values and don't forget to change seed. Never use default seed! If you add chamfer modifier, you then can use some selection modifier to select only edge vertices based on curvature. I used tySelect for that, but you can use data channel. After some tweaking of the settings, you should be able to achieve pretty convincing results.

By the way, it seems that you already asked similar question some time ago: https://forum.corona-renderer.com/index.php?topic=40773.0 Didn't that method work for you?

This looks awesome, do u think u can upload the max for me? so i can check how u exactly did it?

Here you go. Just keep in mind that you'll have to have tyFlow installed, otherwise the effect won't work as intended. Free version is plenty enough.

Thanks so much
