From 3b6ee8cee7080af200e25e944fe30d310240e138 Mon Sep 17 00:00:00 2001 From: Hans Goudey Date: Tue, 13 Jul 2021 12:10:34 -0400 Subject: Refactor: Move vertex group names to object data This commit moves the storage of `bDeformGroup` and the active index to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility functions are added to allow easy access to the vertex groups given an object or an ID. As explained in T88951, the list of vertex group names is currently stored separately per object, even though vertex group data is stored on the geometry. This tends to complicate code and cause bugs, especially as geometry is created procedurally and tied less closely to an object. The "Copy Vertex Groups to Linked" operator is removed, since they are stored on the geometry anyway. This patch leaves the object-level python API for vertex groups in place. Creating a geometry-level RNA API can be a separate step; the changes in this commit are invasive enough as it is. Note that opening a file saved in 3.0 in an earlier version means the vertex groups will not be available.
