Meeting Notes

  • Development Updates
    • Lukas and Yiming worked on porting the GPv2 modifiers. The Subdivide, Hue/Saturation, Opacity, and Tint modifiers have been merged already. Many more are in review. You can follow the progress on the overview task here: #106665: GPv3: Modifiers
    • Bastien worked on the edit mode undo. There is a working PR here that’s under review.
    • Falk worked on layer transforms and layer parenting. The PR #117247: GPv3: Layer Parenting/Transforms is working and under review.
    • There is also a PR for Onion Skinning #117064: WIP: GPv3: Onion Skinning but this is not working yet (especially the rendering part).

  • Discussion on the topic of Vertex Groups:
    • The weight data for vertex groups is stored per drawing. This is different to other objects where there is just one geometry in the object data and the vertex group names can be stored on the object-data.
    • Idea: Store a list of names on the object-data that defines the order of the vertex groups in the UI. When vertex groups are added/removed, this list is updated.
