Weird results beveling edges

[Anonymous]

So, I've recently come back to using maya after using max for quite a while. I'm running to an issue that's driving me insane on something that should be a simple task. All I'm trying to do is bevel some edges but maya is offsetting the bevel in a way that is unsatisfactory. Instead of just splitting the edge, it's putting a weird angle on the new edge, like it's rotating it instead of just splitting them straight.

I exported my model and bought it into max just for a comparision and max bevels (chamfers) the edge how I would expect it to behave. Anyone know wha'ts different about how maya deals with bevels and how could I get my bevels to behave like max's chamfers??

Thanks in advance!

The bevel shown below was done with the settings that are also shown below. Compare them to yours and see if there's anything different (other than the bevel numerical values.)

Thanks for responding. Those are the default bevel settings and when I use those I get the same behavior. It doesn't do it on primitive geo. Only with the new geo that I've modeling

Actually, I took a plane and extruded it before beveling an edge in an attempt to make it look like your Max bevel. Can you zip and upload a scene with some geometry that isn't beveling properly? It might make it easier to troubleshoot.

Oh cool. It happens on all my geo which is weird. I bought the exported fbx back into maya and it still does it. The same fbx when imported into max bevels fine.

I've attached an fbx. Thanks for helping me out with this!

Yup...for some reason, Maya hates beveling that edge. The geometry is clean...no extra vertices or anything. What's odd is that if you select the entire object and bevel it, the result along that edge looks right. (Unfortunately, you end up with a bunch of extra edges all over the object when you do that.) 

I even exported it as an OBJ and tried beveling that edge in Blender, where it worked perfectly. (Don't you hate it when free software works better than the expensive stuff?)

Sorry I don't have better news! Maybe someone else knows a trick that I'm not aware of...

Well, thanks for looking into it! It must be just a maya bug, perhaps specific to 2016 since that's the version I'm using. It works fine in max tho. It's very annoying. Thanks again!

WAIT!!! I figured out what the problem is. You're right...it's a 2016 bug. The "use legacy bevel algorithm" is not working...and it's what you need to make that bevel look right. Looks like that checkbox somehow got disconnected from the code.

Try this:

Paste the code below into your MEL window.

Triple click the code to select all if it, and middle-mouse button drag it up onto your toolbar.

Click MEL in the "Save script to shelf as type" dialog box pops up.

You can now use that button as your legacy bevel command. To edit the parameters, you can right-click on the button and edit as needed.

Dude, that worked!!! Thank you so much for looking into this!! You have no idea how much headache you've saved me from.

Happy to help! Hopefully @santd noticed this thread and the solution, and can verify and get it fixed for the next service pack. (Probably take a programmer about two minutes to fix it.)

Hi @pshwayka and @Anonymous,

I found a few different issues logged with our development, but I logged another one regarding this for good measure. Development team will be working on a resolution for this.

Cheers,

Thanks David!

Awesome! Thanks guys!!

Still not fixed in SP5...and I thought this would be low-hanging fruit.

SMH...

Yea I hope too that the "use legacy bevel" option will be re avabile in the future: 1 in 50 situations that works better than the new one.

Maya 2016 SP6 - still this "use legacy bevel algorithm" is not fixed.)

[iandestercke]

Is it just me or is this still not fixed?
