Cody Winchester (CodyWinch) added a comment to D7283: Weld Modifier - Average vertex weights of welded vertices.

Are there any situations where the current behavior of adding all the vertex weights together and then clamping is actually preferred?

I'm not sure I like the idea of adding an option for behavior that most people expect anyway. (IMO the current behavior mentioned above of adding them up would not be expected)

If the option is necessary for performance I'd rather have a choice between "Nothing" and "Expected Behavior" than a choice between "Unexpected Behavior" and "Expected Behavior".

Germano Cavalcante (mano-wii) changed the status of T80893: Complex Solidify Crash with Singularity on Rim from Needs Triage to Confirmed.

When testing, I came across this assert:

BLI_assert failed: ...\source\blender\modifiers\intern\MOD_solidify_nonmanifold.c:2441, MOD_solidify_nonmanifold_modifyMesh(), at 'loop_index == numNewLoops'

Zachary (AFWS) added a comment to D8943: Boolean Modifier: operand display operator.

On one hand I think this is a really handy operator that could speed up this workflow a lot. However, I wonder if this is solving the problem in a way that's too specific to this situation.

It also doesn't solve a few similar problems with this workflow: setting the render or viewport visibility.

Here is a more general way this could be done:

  1. Add this in the right click menu for collections in the outliner.
  2. Add a shortcut on these ID selector buttons to take you to its location in the outliner.

And another would be adding this to the existing right click menu for ID selector buttons, which already contains "Jump to Target".

I don't necessarily think these ideas are better, just that more similar solutions should be considered.

Germano Cavalcante (mano-wii) updated subscribers of T80839: Subdivision Surface: Out of memory exception in in post 2.79 versions.

This problem is caused by the new blender subdivision modifier which is unfortunately slow with non-quad faces.
It is already known issue and will be addressed with the tasks:
T60733: Subdivision Surface Performance Degrades Markedly With Non-Quad Meshes
T73564: Adaptive subdivision modifier takes to much memory

Jacques Lucke (JacquesLucke) changed the subtype of T54488: hair disconnect/reconnect not working with modifiers from "Bug" to "Known Issue".

It seems unlikely that someone will work on this before the new hair type is usable. Therefore, I'll reclassify this as known issue.

Rodrigo (Takain) closed T80813: Buggy Solidify modifier? not a normals problem. and is only fixed when applying rotation as Invalid.

not a bug, caused because you had 0 scale on z, and was solidifying to the z (local) direction

Germano Cavalcante (mano-wii) changed the status of T80768: Subdivision Surface modifier uses viewport subdivision settings when rendering in edit mode from Needs Triage to Confirmed.

It seems to be a problem related to the one described in T73344: Modifiers disabled in viewport are not rendered if the object is in edit mode.
But perhaps the cause is entirely different.
So I am confirming this as another bug.

Henrik Dick (weasel) claimed T80269: The material in the Complex mode in the Solidify modifier is wrong.

I will fix this in the upcoming days hopefully. I would rather change complex solidify to fit simple solidify even when the behaviour of simple solidify was strange. Otherwise older files using that feature would need versioning to be converted to the new version. (which would not be that big of a deal, if someone has a strong opinion on this let me know).

Thanks but I just found a bug with that to if I try and change the "Thickness" value more than twice It causes Blender 2.91.0 alpha to fully crash. But it is an Alpha

Amos Manneschmidt (amoose136) added a comment to T80548: Using Solidify with Boolean modifier closes hole / unexpected results.

Note that exact calculation are considerably slower than simple floating point boolean operations and if the solidify modifier is producing a self intersecting mesh, you will also need to enable the "self" checkbox on the boolean or it still won't work. Enabling self intersections is also MUCH slower. Expect to wait like 15-30 seconds.

Howard Trickey (howardt) closed T80522: New Boolean Exact fails with operand that has intersecting elements as Resolved.

Yes, the 'self' option was added very recently and is intended to solve exactly this case: when one of the operands has self intersections. One might argue that this should be the default but it results in slower execution, so for now am not making it the default.
