Two files for testing. They both are a uv unwrapped cube, however the data is stored in different order.
With the old code, they get different hashes, with the new code, the hash is equal.

Philip Holzmann (Foaly) added a comment to T54362: OBJ import - same named .obj entries are appended to one mesh / not extra objects.

I'd say this is not a bug.
The same group name can apparently be reused, and refers to the same group.

Philip Holzmann (Foaly) updated the diff for D3092: Array modifier: Do not merge vertex groups with different names.

BKE_object_defgroup_index_map_apply now removes all weights with invalid def_nr.
If totweight is zero, it will be freed.

@Campbell Barton (campbellbarton) I'm not sure how to do that then.
If we want to keep vertex groups that are out of range, there are different possibilities:

  • Map all invalid indices to -1: That could result in a vertex having multiple MDeformWeights with the same def_nr. Also, I don't know if these weights can ever be accessed again.
  • Keep all invalid indices: Weights that do not have a mapping to a vertex group in the new mesh keep their def_nr. This means some vertex groups might be merged.
  • Keep invalid indices only if they are out of range: Weights that do not have a mapping and are >= totweight are kept. This should not cause problems. But it has to be decided what to do with the weights with valid indices but no mapping, so they don't merge. (Move above totweight or map to -1?)

Philip Holzmann (Foaly) added a comment to D3092: Array modifier: Do not merge vertex groups with different names.

Demonstration File to show that def_nr can be out of bounds, created with Boolean Modifier "Union" in 2.79:


Add a vertex group to the object and go into edit mode. Click "Select" to see the vertices assigned to the group. The right cube will be selected.

Philip Holzmann (Foaly) updated the diff for D3092: Array modifier: Do not merge vertex groups with different names.

Vertex Group Merging is now two functions in BKE_object_deform.h.
Used by Array Modifier and join_mesh_single.

Philip Holzmann (Foaly) added a comment to T53206: Unexpected merging of vertex groups with different names.

I have added a patch, but I don't know if I did it correctly.
If you can see it: Is it okay to fix it that way?

Tried it on GPU. I also get the fireflies.
And I noticed: the bigger the cylinder, the more fireflies.

Philip Holzmann (Foaly) added a comment to T44895: Volumetic Emission shader disappear in Render.

I just wanted to report the same thing...
This is pretty weird, because it works in the viewport.
And it is not true, that it is completely invisible, there are some strange artifacts around the mesh border.

Philip Holzmann (Foaly) added a comment to T44401: Mirroring in Object Mode is inconsistent.

I did not know that this behaviour was intended.
But I think there is no point in having a mirror operator, if it can't mirror rotated objects.
I sometimes create objects wich are linked copies (so I can't just apply the rotation) and having to parent them to an empty to mirror them correctly is a bit weird.

Sorry, I should have checked that before reporting the bug.
