As you can see the bevel function works when free to operate without any LIMIT set. Object scale is 1, I can't see any issue anywhere.

enter image description here

Here it's with LIMIT set to ANGLE. Angle is to 30, many edges are at 45 or 90 degrees, none gets beveled:

Here I tried with 2 edges with MEAN BEVEL WEIGHT at 1:

Again no effect:

There must be some geometry in your model that results in overlapping geometry after bevel so the bevel is stopped at that point by Clamp Overlap feature:

enter image description here

Resulting geometry differs with different Limit Method, so it must be the case with angle limit but not with no limit. There is no other explanation.

  • $\begingroup$ I thought of Clamp Overlap too, but if this is enabled it clamps even if you have set the Limit Method to None... but maybe I just cannot find a constellation of vertices/edges where this happens. $\endgroup$ Dec 12, 2023 at 10:45
  • $\begingroup$ Yes it does clamp in both ases. But the resulting geometry itself is different when beveling with limits and without, because different edges get beveled(or not), so it must be that it happens to have overlaps with the particular edges beveled with limits, but not when all edges are beveled. I don't think it's very likely to be any other mysterious cause. We'll see when/if the file is shared for sure. $\endgroup$ Dec 12, 2023 at 10:51
  • $\begingroup$ Yeah I found it is easy to do something the other way round: clamping when set to no limit, but not clamping with an angle limit. My problem is I cannot figure out what geometry issue might be the trigger here, so I do not know what answer I could offer to solve it (sure, disabling clamping might help with the symptoms but not the cause). $\endgroup$ Dec 12, 2023 at 10:56

    $\begingroup$ @PolyMad That's the question. Pretty sure you have something messed up there, but if you already tried to look for it and did not find it, we might need you to upload your model to see for ourselves. Because as I mention above, disabling clamping only removes the symptoms, not the cause for the problem. Martynas: Of course that's what we are going to look for - this was my point, we need the file to really help solving the issue instead of just making it look okay... basically I think this answer is a workaround - but it got accepted, so I would not bother anymore to find the real problem ;) $\endgroup$ Dec 12, 2023 at 11:55

    $\begingroup$ Found the problem. I have 4 booleans active on the object. I added a vertex weld modifier right after all of them, before the bevel modifier, and that fixed the problem. Clearly one or more boolean were producing very close vertexes that limited the amount of beveling possible. Thank you everyone for the help! $\endgroup$
