Development Updates
Campbell

  • Worked a little bit on the UV sync select feature (task #136817 - UV Sync select progress - blender - Blender Projects). Other stuff came up so not as much time as he’d like. Wants to improve the way UV selection works. If you select a face and move it, don’t want that to rip things apart. Could be a performance problem, so a little hesitant to try this. But only happens on boundaries, so probably acceptable. Also want to expose the sticky selection option. Other thing: removing selection from the UV layer (not store per layer, in other words). Daniel and Jonathan don’t think this will be an issue.
  • Campbell asked: if one is selecting a vertex in 3d view that is shared between two islands: what if you click just inside one face to say which island’s vertex you want selected in the UV view: would that be useful?
    • Daniel: could be.
    • Jonathan: sounds like a very useful feature.
    • Campbell: might get complicated if there is more than 2 islands and want some subset of islands selected in UV view. Jonathan: this capability sound very useful.
    • Daniel: box or circle select might be useful when you want to select more than one island.

Howard

  • Manifold Boolean landed in main, so will be in 4.5 release. Modeling: Add a new boolean solver based on the Manifold library. · dd559259d8 - blender - Blender Projects
  • Fixed several bugs so far; there’s another couple to investigate still. The upstream manifold developers are very engaged and responsive to bug or issue reports.
    • Campbell: good to get as much stuff tested and fixed as possible while they are still active.
    • Howard: yes, unresponsive maintainers of Cork solver in the face of new bug reports was what caused us to remove it a number of years ago.
  • Before that, made some more progress on bevel geometry node. A contributor, Piotr Makal, has said they will try to make a prototype of a new approach to UVs. Asked Daniel and Jonathan how they would trade off between things like a choice between maintaining equal scale of faces in the UV space vs overlapping of faces in UV space. Both said that they learn about and understand the limitations of what happens in such cases, and adjust their workflow accordingly.
