Faced with a problem that causes crash Blender 2.80. For automation I created a script from a sequence of actions which works great if I run it in the blender console window, or if i Run Script in a text editor.
But when I run this script through the command line without the graphical shell of the blender - he crashed.
Еhe exception method was used to find the reason. This is the command bpy.ops.object.material_slot_assign ()
She is responsible for applying the material to the vertices in Edit Mode.
import bpy bpy.ops.object.editmode_toggle() bpy.ops.mesh.select_all(action='SELECT') bpy.context.object.active_material_index = 1 bpy.ops.object.material_slot_assign()
If I exclude bpy.ops.object.material_slot_assign (), the script succeeds, except that the materials are not used.
Who knows how to get around this command?
