Short description of error

There seem to be a regression in the python API when extruding faces using bpy.ops.mesh.extrude_region_move

Exact steps for others to reproduce the error

Trying to re-use an "old" blender script to modify a geometry, I've ended up finding what looks like a regression when using bpy.ops.mesh.extrude_region_move

The "broken" code in question:

# normal = Vector()
bpy.ops.mesh.extrude_region_move(

MESH_OT_extrude_region={"use_normal_flip": False, "mirror": False},
TRANSFORM_OT_translate={"value": (0, 0, -0.5),
"orient_type": 'NORMAL',
"orient_matrix_type": 'NORMAL',
"constraint_axis": (False, False, True),

                            - the fix is to use the orient_matrix parameter
                            - "orient_matrix":((0, 0, 0), (0, 0, 0), normal),

})

When run with 2.90, the faces are not extruded "along normal" the way they used to be in 2.83, the orient_matrix parameter needs to be used (I still have no idea what this actually changes)

Sample

The attached .blend file should make my example clearer I hope

The script should extrude the faces of the cub inwards when ran

2.83
{F9200866, size=full}

2.90
{F9200869, size=full}

I can reproduce this in 2.90.1, but it appears to work as expected in Blender 2.91 and 2.92.

There have been several changes to the transform orientation over the last year. At the moment I can't tell without bisecting which commit broke this for 2.90.1 and which fixed it for 2.91.0. Please check if this is working for you in the current daily build of 2.91 as well. In that case I think we can consider this fixed.

388b916246 edited this area mainly.

The orientation initialization code was practically redone on that commit, so it is quite possible that it fixed some unpredictable bug.

Please try the latest daily build: https://builder.blender.org/download/

If the problem persists, please let us know so we can re-open the report. Don't forget to mention the specific version you tested again.

Tested with 2.91, this is indeed fixed

Many thanks
