BM_mesh_partial_create_from_verts_group_multi()

BMPartialUpdate * BM_mesh_partial_create_from_verts_group_multi ( BMesh & bm, const BMPartialUpdate_Params & params, blender::Span< int > verts_group, int verts_group_count )

nodiscard

All Connected, operate on all faces that have vertices in the same group.

Reduces computations when transforming isolated regions.

This is a version of BM_mesh_partial_create_from_verts_group_single that handles multiple groups instead of a bitmap mask.

This is needed for example when transform has mirror enabled, since one side needs to have a different group to the other since a face that has vertices attached to both won't have an affine transformation.

Parameters

verts_group	Vertex aligned array of groups. Values are used as follows: >0: Each face is grouped with other faces of the same group. 0: Not in a group (don't handle these). -1: Don't use grouping logic (include any face that contains a vertex with this group).
verts_group_count	The number of non-zero values in verts_groups.
