Howard Trickey (howardt) added a comment to T58822: Bevel tool (and modifier) doesn't work properly.

Yes, I see the problem. You can work around it by turning off the 'Loop Slide' option.
There's some complicated optimization that goes on to try to even out the loops when loop slide is on, and looks like there might be a bug in that.

Yes, you are correct. I guess the previous CL that I thought fixed things just moved the problem around.

This is similar to, probably the same as, the issue discussed in T47129.

Howard Trickey (howardt) reopened T57620: Loop normals display not working if have custom split normals as "Open".

Campbell, your recent commit rBff3601b9 seems to have broken some of the code that was written to fix this, or maybe just broke the code that fetches and uses custom normals in shading. Now when autosmooth is on it doesn't seem like the workbench display uses custom normals at all (e.g., trying to modify them with the mesh -> normals -> point normals to target command, using m for mouse -- nothing happens now).

Howard Trickey (howardt) added a comment to T58265: Blender 2.8 Beta crashing in Sculpt Mode.

Somehow the memory allocator data structures got corrupted so that it returned the same value for both the edge pool and the loop pool allocations (!).
I'll have to did deeper to understand which code is doing the corrupting. I tried Valgrind, but no luck.

Howard Trickey (howardt) claimed T58113: Bevel harden normals modifier, tool, and Python op all have bugs.

The proper thing to do is to share the normal hardening code by putting it in BM_mesh_bevel(), rather than the current strange mix of having some of the work done in that function but most of it done (separately implemented) in the modifier and in the editmesh code that runs after the BMOp bevel runs.

Howard Trickey (howardt) closed T57868: bmesh.ops.bevel crash (Segfault) as Resolved.

OK, so the crash was because one also needs to do a bmesh.update_edit_mesh(C.object.data) after running the above commands, and it is documented that one needs to do so. It all seems to work fine (though without hardening normals, if that is specified in the arguments) now.

Howard Trickey (howardt) added a comment to T57868: bmesh.ops.bevel crash (Segfault).

The immediate problem was that no verts were in the input geometry, and code assumed that if edges were there then verts were there. The code in the second update added the verts. But I fixed the code to add the verts from all edges explicitly so that this would no longer be necessary.

You are not being a nuisance. I appreciate hearing about the real-world problems people have.

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

I've looked at this some now.
There is no quick, easy fix. So this will take some thinking.
The problem is that we have to decide which side of a seam to put the bevel parts on. In the provided example, the side has been chosen consistently so that there is pleasing overall symmetry. I need to see if I can think of an algorithm that has that effect.
In addition, there are the triangular corners that now get mapped to go only halfway across their adjacent edges. I'm not sure why that is. Needs more debugging. Bug also not clear if just having them extend all the way across the adjacent edge would satisfy the bug reporter.

Howard Trickey (howardt) added a comment to T54054: Bmesh boolean modifier fails with co-planar geometry (carve doesn't).

Despite this having been closed, I still intend to spend some cycles seeing if I can make the bmesh solver handle at least some of the coplanar cases. Carve seems to have worked sometimes but not consistently - from what I can read, it is not claimed that it works in those cases but I guess sometimes it did. The algorithm Carve used was completely different from that used in the BMesh code, so pretty hard to just adapt the parts that may have been solving the coplanar problems. As to why not just leave Carve as a backup: existing developers got tire of all the bug reports against Carve (crashes, not working in certain cases); combine that with the general difficulty of dealing with external libraries (dependencies, versions, hard to push fixes upstream, rot when new compiler versions don't work, ...) led to the decision to remove Carve now that BMesh boolean does pretty well in the general (non-coplanar problem) case.

Feb 12 2018, 9:16 PM · Modifiers, BF Blender
Howard Trickey (howardt) claimed T54054: Bmesh boolean modifier fails with co-planar geometry (carve doesn't).

This is not something the current bmesh boolean code was intended to handle (coplanar intersections). So one could say that this behavior is "working as intended" (where "intended" = "undefined" in this case). The user can, of course, move one of the planes very slightly to get it into "defined" territory, but understood that that is tedious for the user especially if there are a lot of things that need to move and no easy single command to find and move all of them at once. So I will take this task assigned to me to see if something can be done, but there is not likely to be a quick fix to this.
