I am trying to write a simple script which should loop through the selected objects (all simple square planes) and do a loop cut operation in order to split the plane in half.

EDIT: What I have runs, but now only cuts the active object:

EDITED IN A SIMPLER VERSION:

import bpy

bpy.ops.object.mode_set(mode = 'OBJECT')


If there ARE objects selected then act on all objects


if bpy.context.selected_objects != []:
    for obj in bpy.context.selected_objects:
        if obj.type == 'MESH': 
            print(">>>>", obj.name)
            bpy.ops.object.mode_set(mode = 'EDIT')


        obj = bpy.context.active_object

        def view3d_find( return_area = False ):
            # returns first 3d view, normally we get from context
            for area in bpy.context.window.screen.areas:
                if area.type == 'VIEW_3D':
                    v3d = area.spaces[0]
                    rv3d = v3d.region_3d
                    for region in area.regions:
                        if region.type == 'WINDOW':
                            if return_area: return region, rv3d, v3d, area
                            return region, rv3d, v3d
            return None, None

        region, rv3d, v3d, area = view3d_find(True)

        override = {
            'scene'  : bpy.context.scene,
            'region' : region,
            'area'   : area,
            'space'  : v3d
        }

        bpy.ops.mesh.loopcut_slide(
            override, 
            MESH_OT_loopcut = {
                "number_cuts"           : 1,
                "smoothness"            : 0,     
                "falloff"               : 'SMOOTH',  # Was 'INVERSE_SQUARE' that does not exist
                "edge_index"            : 1,
                "object_index"          : 0,
                "mesh_select_mode_init" : (True, False, False)
            }
        )

Seems the problem stems from the active object being the only thing taking the loop cuts. Help on where I've gone wrong would be great! Thanks!

    All selected objects will be put into edit mode. Can set the active object with context.view_layer.objects.active = obj or add teh object to the overrirde, since all are in edit mode.

  • I'm not sure I understand how to implement this code snippet, nothing changes when adding that in the loop body. – Austin Lelonek Apr 18 '21 at 00:12
  • bpy.context.view_layer.objects.active = obj is what I needed! Note the prefix bpy.* is the only thing missing. Can you add an answer batFINGER – Austin Lelonek Apr 18 '21 at 00:33
