Corona Wire Map renders the edges with some sort of fading closer to the vertices. Is it me doing something wrong, is it intended to work like that, or is it some sort of a bug?
See attachment.
After some searching I couldn't find this issue on the forum.

I can't reproduce this issue on my end (see attached).
I guess there may be something wrong with your geometry: check for non properly welded vertices, overlapping faces, flipped normals, bad smoothing groups ... that kind of things.

Thank you for the reply Tom!
I am absolutely confident that this is not caused by bad geometry -- I make models for a 3D stock, so I always make sure my meshes have no overlapping vertices/edges/faces, and I successfully UV unwrap them. I also don't think this is caused by shading, because I always do proper smoothing on my meshes.
I forgot to mention that I have this issue on Corona 9 Hotfix 2.

It's not an issue caused by a bad geometry, nor a bug per se. It's just the way how Corona wire map works. It looks even worse when you use turbosmooth with isoline display ON. This and few other issues has been plaguing Corona wire since the beginning, devs are aware about it and improvements are promised, but no one knows when that might happen.

Hi,
This is reported in our system as a bug. We will let you know as soon as we have any update on this.

Thanks for the feedback guys, glad it's reported, and I hope for a fix soon.
But why don't I have this issue then? Not that I miss it, but I'd just like to understand.
I understand the Turbosmooth modifier with Isoline display On makes things worse, but does it depend on the model you're using the effect on as well?
-
I'm pretty sure you have this issue too, it's just it's not always very obvious. Try to render more close-up shots, also play with wire map settings, like edge width and falloff and at some point you should see the issue quite clearly.
-
The issue is not very obvious. It only becomes visible if your camera is very close to the model and if the model is either heavily subdivided or extremely low-poly.
-
It is not very obvious, that's true, but it also true that it gives Corona wire renders untidy, messy look in almost every scenarios, even if sometimes you can't point your finger at exact cause of it.
-
Another good business case for getting a dedicated edge outline shader rework aka all those requests for the equivalent edge control of VRay Toon.
-
Definitely agree!
The number one feature that I miss in Corona is a VRayToon effect equivalent, definitely. I use it in all of my projects.
