Weird Bevel Issue

[Henry Smith]

When I use the Bevel Modifier it creates these weird edges on acute angles.

 Have a look at the images below.

Interesting, it looks like that non-ideal geometry shows a current limitation of the bevel modifier. There will be someone working on fixing it this summer, but in the meantime you might need to bevel that area in edit mode. This addon looks like it would make that process a lot better, but I haven’t had time to try it out just yet: https://www.blendermarket.com/products/MESHmachine

It is very unusual that this happens to me and not you. I am using the same version as you are in the tutorial. It happens on very simple geometry as well.

Hmm, what does the surrounding geometry look like before beveling? If that top vertex is connected differently (like if it’s a pole) than I could see why it would come up with two different results.

I am using a default cube extruded on two sides to simulate the issue.

Using a Ngon:

Interesting, for me it only happens when I have an n-gon:

Mind if I look at the file? I can’t find a way to replicate it on my end. 

[Henry Smith]

How should I send you the file?

[Jonathan Lampel]

I’d recommend pasteall.org

Here you go.

Oh I see, so the difference is that one of the top edges is being beveled while the other one is not: 

If none of the automatic Limit Method options are working, you can set it to Weight and then assign the bevels manually from the Transform section of the viewport properties panel. 

[Henry Smith]

How come this does’nt happen on your model when you do the same thing?

[Jonathan Lampel]

It’s the exact same behavior, it’s just that mine must have the edge that’s on the flat surface beveled as well. 

[Henry Smith]

If the flat edge isn’t evenly in between the beveled edges it stretches those sides. Not Ideal.
