Brecht Van Lommel (brecht) updated subscribers of D6935: Modifiers: Subsurf modifier and Multires modifier add option to preserve and interpolate custom normals.

Sergey is rewriting Multires modifier in a local branch according to his weekly report . So you may want to submit the changes to each modifier separately?

Hans Goudey (HooglyBoogly) updated the diff for D6470: Add Free Handle Types to CurveProfile Widget.

Use RNA directly for updating the handle types. This proved difficult because the points on the path didn't have a reference to the profile itself, which needs to be updated.

Sybren A. Stüvel (sybren) changed the subtype of T50423: Adding new hook while in Edit mode breaks when trying to undo/redo the operator from "Bug" to "Known Issue".

The problem is that an action can either store an undo step for edit mode (which doesn't include things outside of edit mode, such as the pose bone properties) or it can store the entire scene in memory (which doesn't include edito mode data). Deleting a bone changes both sets of data, so it cannot be properly un-done with just one step. This is a limitation that needs proper design work to resolve.

Anyway, I'll be happy with such optimisation, because mostly I work with static scenes and sculpts.

Bastien Montagne (mont29) changed the subtype of T73199: Switched off Boolean modifier still recalculates if there is second one, that switched on from "Report" to "Known Issue".

Issue here is that for the depsgraph, it has no knowledge whether the modifier is disabled or not, so it keeps following the rules established by the relations generated in updateDepsgraph() modifier's callback.

Nathan Vasil (vasiln) added a comment to T73941: Custom normals from normal edit modifier ignored by further modifiers.

I was mistaken about this being also true of data transfer modifier. Custom normals from a data transfer modifier are being read correctly by a displace modifier. For that matter, they're also reading custom normals from a normal edit modified mesh appropriately. In fact, this can be used as a workaround-- make one mesh, likely non-rendering, to get the normal edit modifier, and a second mesh to copy normals via data transfer from the first mesh.

Bastien Montagne (mont29) added a comment to T73941: Custom normals from normal edit modifier ignored by further modifiers.

@Philipp Oeser (lichtwerk) poly normals are not custom/loop normals... The latter are for sure expected to be passed around in modifier stack.

Germano Cavalcante (mano-wii) added a comment to D6270: Place center of bend modifier at origin.

@toran (toran),
This would break the old files that were saved with this modifier.
If you can make it configurable so that it doesn't break old files, I think it would have a better chance of being accepted.

Philipp Oeser (lichtwerk) updated subscribers of T73941: Custom normals from normal edit modifier ignored by further modifiers.

This behavior is also inconsistent with the behavior of custom normals set via a weighted normal modifier. When that modifier is used, it seems to affect further modifiers appropriately.

Not sure about this, can you provide an example file where this works?

In this video you can see the speed reached in 2014 on Blender. Was the same test done in 2.8?

Riccardo Russi (RRR69) added a comment to T70826: Subdivision modifier slower than Blender2.79 non-OpenSubDiv in edit mode.

I don’t see any substantial improvements in 2.82.7
Playback is incredibly slow when the Subdivision modifier is applied to a mesh with animated shapes or bones.
In 2.79 and Maya it is tens of times faster.

Also, the provided file has the bones using Absolute custom handles and the Start custom handle bone has its head at the same coord as the bbones head which causes roll issues.

I have been looking into this and it seems this has nothing to do with the shrinkwrap modifier. It is the result of changes to the bbone roll calculation.

Frank Olthuis (Fury) added a comment to T69234: Difference boolean doesn't work properly if the object that is used to cut has its normal direction outside (Isolated occurance).

Simplified version of the first file:


The fact that the center vertices of the cylinder coincide with the top face of the cube is critical. Possibly related to T68144.
