From 3306b4a86bb8dcb0a1640fc73c355e5fff9073a7 Mon Sep 17 00:00:00 2001 From: Hans Goudey Date: Tue, 30 Aug 2022 10:41:26 -0500 Subject: Fix T99253: Missing face center dots with deform modifier cage option Before 8c25889bb67db4c, subsurf face center tags were stored in each vertex, so they were always copied to duplicate meshes. Now they are stored in runtime data though, so they need to be copied explicitly. The function name "reset_on_copy" is a bit awkward here, so the tags are copied by the caller. --- source/blender/blenkernel/intern/mesh.cc | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/source/blender/blenkernel/intern/mesh.cc b/source/blender/blenkernel/intern/mesh.cc index cf05dc0404e..afd8e49f884 100644 --- a/source/blender/blenkernel/intern/mesh.cc +++ b/source/blender/blenkernel/intern/mesh.cc @@ -96,6 +96,10 @@ static void mesh_copy_data(Main *bmain, ID *id_dst, const ID *id_src, const int const Mesh *mesh_src = (const Mesh *)id_src; BKE_mesh_runtime_reset_on_copy(mesh_dst, flag); + /* Copy face dot tags, since meshes may be duplicated after a subsurf modifier + * or node, but we still need to be able to draw face center vertices. */ + mesh_dst->runtime.subsurf_face_dot_tags = static_cast( + MEM_dupallocN(mesh_src->runtime.subsurf_face_dot_tags)); if ((mesh_src->id.tag & LIB_TAG_NO_MAIN) == 0) { /* This is a direct copy of a main mesh, so for now it has the same topology. */ mesh_dst->runtime.deformed_only = true; -- cgit v1.2.3
