Artifact when creasing inner edge

posted to: Filling the Voids

Hi.

When I try to crease the inner edge. I'm getting an artifact on a surrounding edge.


Some scrngrabs before crease and after crease in my response below.

    My first thought is that it's being caused by double verts. Try going into Edit mode, select all, M>Merge by distance and see if any vertices are merged (there will be a message at the bottom of the window) and if it helps the crease. Let us know!

    Hi Coyo,

    That was my first thought as well and then I thought it was the normals so I did shift N. I even removed that corner vert and rebuild it. But the same thing keeps reappearing. I also removed the Subdiv modifier and added him. Same artifact keeps reappearing.

    Hi Jonatan ,

    That is probably just an effect you get with Creasing, when you are also using Subdivision Surface (I rarely use Creases, to be honest, so I am not an expert). Holding Edges are usually the better choice.

    But, what you can try, is extending the Creasing to some of the connected Edges, with minimal weight. 

    Have a look at JLampel doing an inner Crease in the Cookie Logo from 1;40 on: https://cgcookie.mavenseed.com/lessons/modeling-a-logo-pt-3

    You can always try the nuclear option, delete some of those faces where the problem is and fill again with brand new faces. That always helps in getting rid of whatever dark magic is happening. And also sometimes when you delete those faces, you see there was an extra face squashed in there that was causing the issue, and you're like, where did that come from? But yeah, you can try that as well.

    Thanks everyone, for your helpful feedback. I eventually went for adding two additional edge loops. This results in turning the triangle in the lower corner into a quad. So new edge loops will run around. But I guess it's better than having the pinch artifact. I tried rebuilding the corner several times but each time it resulted in the same thing.
