@Brecht Van Lommel (brecht), should this be merged, or do we come back to this patch when Blender 2.8 is released?

Ish Bosamiya (ish_bosamiya) added a comment to D4530: Join Triangles Modifier.

How feasible is it to add a tick box to stop re-evaluating the base
mesh after the evaluated mesh has been generated and cached,
that way the modifier can still work with animation without beeing applied?

If this is used in animations the tri to quad conversion will 'pop' on deformation.

Can you point to where this was requested? Were example use cases given?

Bastien Montagne (mont29) closed T52873: Vertex Weight Proximity breaks Rigid Body simulation as Archived.

Yes, this is indeed a chicken & egg issue (and yes, it also happens in 2.7x). Guess we can close that as known limitation for now, then.

Sergey Sharybin (sergey) added a comment to T52873: Vertex Weight Proximity breaks Rigid Body simulation.

But same happens in 2.7?
This sounds like a feedback loop between rigid body simulation which needs geometry for the collisions, but geometry needs transform for modifier stack. While we can avoid some dependency cycles here, the order of updates might be wrong from users perspective. And the only user-controllable solution here would be to go node based.

Bastien Montagne (mont29) added a comment to T52873: Vertex Weight Proximity breaks Rigid Body simulation.

Deg warning about DEG_OB_COMP_GEOMETRY relation is now fixed, but the rigid body simulation remains completely broken in 2.8 currently here (neither of the two displace modifiers work, only really moving red object works currently).

Bastien Montagne (mont29) added a comment to T52873: Vertex Weight Proximity breaks Rigid Body simulation.

Using an empty (or center point of any object) is a valid usecase of this modifier, will check on those relations tagging.

Sergey Sharybin (sergey) reassigned T52873: Vertex Weight Proximity breaks Rigid Body simulation from Sergey Sharybin (sergey) to Bastien Montagne (mont29).

The issue in code i saw was related on a fake dependency cycle, which is now fixed in rB099a4104788.
Now i can open the file and there is a playback going on.

Or the triangulate on Ngons, this is just an option to add to the triangulate modifier and it would help a lot!!!!!!

Hi, It would be very useful for me to have the vertex group or any other way, to affect bevel size per vertice, something like this:


I added the image to the right click select post too, please let me know if it is not ok here, thanks!

Thank you,
that is sad for me unfortunately since there is no other way to do this in blender without just working on geometry and loosing editability :( this was a great feature for me, on this project and other stuff ive used it before (RIP).

Howard Trickey (howardt) closed T62739: Bevel Weight not affecting Bevel modifier correctly as Invalid.

Sorry, I am closing this as "working as intended" because the code is doing what I intended: that is, it is choosing to keep widths even along their edges as a higher priority than trying to half-way meet an unmeetable set of width constraints.

Howard Trickey (howardt) added a comment to T62739: Bevel Weight not affecting Bevel modifier correctly.

The behavior in 2.79 is not really intended -- it is more an accidental consequence of a choice made to solve conflicting specifications.
What the specifications say is that one edge is supposed to have one particular bevel width all the way along it, and the other edge (with the adjusting weight) is supposed to have another weight all the way along it. Where they meet is a conflict. The conflict used to be solved by taking an average, which gave the smooth tapering effect you saw. But for other cases (especially when there are loops) that is not nearly good enough, so I switched to using a least-squares optimization some time in the 2.79 series (I see that you note that this was working for a while in 2.79 and then stopped working, so maybe that was when I made this switch).

Sebastian Parborg (zeddb) claimed T62008: Blender 2.8 subsurface modifier bug..

The issue here is that the new subdiv code uses the limit surface (the surface of the cube is you subdivide it an infinite amount of times) to place the verts.

I believe that export, operator and modifier all share the same base code. I'll get the modifier working first and we can go from there.
