Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
See file: shoe_packed.blend
In edit mode it works fine. But in object mode the shoe is black. If I triangulate the mesh it works fine.

(For the records, console shows: Error: Tangent space can only be computed for tris/quads, aborting)

This is caused by the use of BKE_editmesh_loop_tangent_calc in object mode.
BKE_editmesh_loop_tangent_calcisnt called in object mode.BKE_mesh_loop_tangents_exis being called instead but it isn't used from Blender's own drawing code (only exposed via RNA).Looking into generalizing
DM_calc_loop_tangentswhich is more comprehensive.This issue was referenced by

Re-opening, some issues still present in the original file.
Changed status from 'Open' to: 'Resolved'
Committed workaround, not sure why split normals cause this but since they're not used as normals, checked its not some array index mismatch so commenting for now - this matches edit-mesh.
