I am confused in that way that the performance slowdown is coming from the modifiers of another mesh object, and not only from the modifiers of the mesh object I am editing. (Since there is no visible live update of shared meshes under certain (modifier) conditions I assumed the meshes are sort of decoupled while in edit mode, and follow with an update after I switch out.)

I have opened the issue a few weeks ago but not standalone: https://developer.blender.org/T71896
So here is it again.

but I couldn't reproduce the problem by changing some shortcut to double-click

@Sergey Sharybin (sergey)
Is this still something that is get looked into for 2.8?
This issue keeps coming back to me mainly because its very comfortable to work with mirrored armature parts. Separate hand armatures for example can be reused and more easily updated this way:

With 0 face object I mean a mesh without faces, not an empty.
You can use it for low poly meshes or stylized geometry (bone meshes, water waves)
or for (roots of) a tree, for example. Simply what you want.

I was not sure where to put this. I guess it looks way more like a feature request, but I found it very surprising or contradictary that the modifier is still working properly with multiple roots, although it deletes all previous with the root button.

I have this issue with every mesh, including all premades (monkey, cube etc).

Wouldnt it then be necessary to mark these options somehow? (Grey out or red modifier name box or warning message if triggered)
Just to prevent further bug reports of this kind from other users as well.

Thank you.

It seems IK stretch loses its target completely if a Pole target is assigned.
Check this by reducing the constraint influence.

May i ask to reopen this case?
Workaround is easy and not really a problem, only sort of annoying. But as zeauro pointed out, this is not consistent to mesh setting.

I think you misunderstand me. Applying works, but isnt a solution where the curve object should keep the object mode rotation. For example to trick the twisting.

Hey,
can confirm this - Skin is working continously and not consistent on branched edges.

Sry if i misunderstood: No problems with the curve tilt (inside - outside), but the direction in which the mesh goes along the curve (left around - right around) isnt controllable in 2D.
I thought it could be a bug, because if i simulate the 2D tilt correction on a 3D curve (Switch direction>rotate Tilt to 180°=beveling preserved) the mesh stays counterclockwise unlike the 2D version.

you can't expect the same behavior from different things...

True, i just wanted to make sure - this issue isnt a big deal anyway.

Cleaner File:

Sry i forgot to change projects, let me edit it! (Game Engine)

Your values should be 50cm*0.01 = 5mm in each direction.
Havent touched this setting until now, but i think if you arent forced to change the Units scale keep it at 1.000.

Was attached. (above picture :D)

Thank you, would be really nice.
But its just a suggestion, dont push yourself.

Sry i didnt want to sound offensive.

Have tried it and found no bug. But i can understand the problem.

can i suggest a delete function which parents children of the deleted object to the upper next object:

Quick question:
Does this patch allow to work on multi user meshes with different/individual EdgeSplit- or Crease-Data?

T41684 is similar or maybe same problem. It could be linked or merged, but I dont know how to do that.

This problem seems very similar to T41862.
It produces the exact same shading like in this case, so i guess its not only game engine related.

The belt mesh got a curve modifier and follows a curve circle (white line) with Stretch & Bounds Clamp options enabled.
As you can see, the ends could use a good merger.
Or you apply the curve modifier instead, but this means you cant use curve any more for animation or pose corrections.

A merge option for meshobject + meshobject (like target object) could handle more - Linked Duplicates (...), so you have only one mesh to work on.
Also comes in place where (...) 2 objects are needed or would be helpful, but result object shall appear as connected. (...)

Copied from D443, added a few comments. Hopefully it works just as i had imagined:

Have experimented with some ideas.
Main purpose i have found in operations where you want to

• tear
• pluck
• peel
• break
• (and so on)

geometry, and of course the other way around.

I will prepare a few examples where i think its useful, but it takes 1 or 2 days.

Ok thanks. But if so, the option should be removed from BG Interface and blocked somehow on game start.
Could be confusing if you dont know where these shading issues come from.

Not sure what you mean, Skin works just fine in BI and Cycles.

About remove doubles modifier:
As we are in place for it, I take Array modifier as example.
Merging array ends after curve deform on a circle is such a problematic case.

General question:
Is it allowed to make suggestions for the Array modifier in this place?

@Hyuri Pimentel (hyuristyle) i want to add:

• A way to copy several modifiers from one object to another at once without overwriting existing modifiers on the target.

So you can reuse parts of modifier setups very quickly.

I have tested bcbbed0 from Thu Jul 31 15:12:50 2014 with the same file.
