Henrik Dick (weasel) added a comment to D8240: Array modifier - Add radial offset option.

If you think you found a better solution for some usecases in this patch, please mention it in D7517 or here and we can combine efforts. Although Campbell would need to give a greenlight on this first to have any future. I have a feeling like this goes something like the colored wireframes or similar "simple" features...

dono dono (dono) added a comment to T62043: Build modifier for Text object builds characters in the reversed order..

Build modifier for Text still works in reversed order.
I think what is expected here is that, with this build modifier and text, first letter appear, then second letter, then third ... But here is first the last letter...

Vyacheslav (hitrpr) added a comment to T77996: Edges, generated with Triangulate modifier looks differend and do not disappear with hiding..

@Clément Foucault (fclem)
Mask modifier can deal with new edges. Object and edit modes both.

Thu, Jul 2, 8:45 PM · Modifiers, BF Blender
Clément Foucault (fclem) triaged T77996: Edges, generated with Triangulate modifier looks differend and do not disappear with hiding. as Low priority.

The different shading is caused by the edit cage rendering on top of the wireframe. This is a known issue (see T64915).

Clément Foucault (fclem) triaged T77976: viewport wireframe not updating after convert to mesh with modifiers as Low priority.

This is almost the same issue as T67888 but in this case it is just because using the convert to > mesh from curve operator.

@Campbell Barton (campbellbarton) I know the eventual goal is to have a better duplicator system, but to me it seems like this patch is a bit orthogonal to that, lots of times you want a contiguous mesh.

Can confirm.
Affected modifiers (at least):

  • remesh
  • bevel
  • decimate
  • triangulate

Clément Foucault (fclem) moved T73944: Generated texture coordinates incorrect on file load in presence of modifiers from Backlog to Bugs on the EEVEE & Viewport board.

The workaround does not even seem to work now. I guess it's a bug in the modifier stack evaluation that think it can skip ORCO since we are in solid shading mode at first.

Howard Trickey (howardt) added a comment to T56625: Bevel modifier UV problem with corners.

The commit rBe3a420c4773a I just made improves the situation here: now a more consistent choice is made as to which UV island gets the extra geometry needed after a bevel. But the original bug report also wants a better shape in the resulting UV map for the interpolated faces. That is harder to fix, and so it remains a Known Issue that the UV map will not be exactly as the original reporter would like.

Howard Trickey (howardt) closed T73966: Bevel Modifier: Inconsistent vertex colors with odd-numbered segment counts as Resolved.

I just committed change rBe3a420c4773a which uses some disambiguation rules to help solve this problem.
I will say it fixes this problem, even though the results still do not look great on the example blend: that example has both a UV map and a Loop color assignment. Those two together make for a harder case to solve (there is a detection of "connected islands" that has to pay attention to both of those maps). If one deletes the apparently unused uv map from the example, the result looks good, in my opinion.

Vyacheslav (hitrpr) added a comment to T73199: Switched off modifier still recalculates if there is second one, that switched on.

Idk if it is correct place, but I have this bit of info about modifiers unnecessary recalculation,
may be it can help to check Blender`s behavior more precisely.
