How to fix Beveled intersections/corners/inner edges?

modeling

#1

Hi all,

I’m pretty new to Blender and am trying to create a 3D type logo. It’s almost done, but I can’t figure out how to fix these inner corners circled in red (see images below).

To create the rounded edges I am using the Bevel Modifier that references the model’s edge data (I gave all the sharp edges a Bevel Weight of 1). It’s then followed up by a Subdivision Surface modifier to smooth things out.

Any help would be much appreciated (I’m not even sure if I modeled this thing correctly so I attached the Blend file).

Thanks!

Use vertex groups, it will give you more control. Adding support loops in certain places can also fix some of the shading issues.

Hi Grim!

Thanks so much for the help! It looks like you also fixed the topology :smiley: I was trying to figure out how to do that.

My mesh was all weird because I had started with and SVG of the J and extruded the curves and then filled the faces with F which gave me a bunch of ngons that I converted to tris and then quads (I know that’s probably a horrible way to do it, but I don’t know the right way yet).

Anyways, could you please explain to me how you created the vertex groups and fixed the topology (I’m assuming it’s the support loops you added, but how’d you do that)?

Thanks,
J

Here is how i did it:

Some hotkeys:
“I” with faces selected to inset
“Ctrl+R” for loopcuts, press a number or roll the mouse wheel to set number of cuts.
“Shift+Select” to select multiple things
“Ctrl+Select” to select shortest path between selection and new selection
“Alt+Select” to select loops
“H” to hide selected
“Alt+H” to un-hide everything

Grim, you’re awesome! Thanks so much for taking the time to do that! Only question I have now is how do I adjust the bevel to make it slightly rounder? Seems like the clamp overlap on the bevel modifier keeps it from changing/overlapping…

Thanks for pointing me to that video pitiwazou! Helped with the topology part for sure :slight_smile:

You can turn it off and then turn down the bevel amount, it will start giving bad geometry and shading at some point but you should still be able to use it as long as it looks right.
