I am stuck. I am trying to smart unwrap objects individually using script.

I tried this code but it fails. Any help is appreciated

import bpy
import time

for obj in bpy.data.objects:
 if (obj.type == 'MESH'):
 bpy.context.scene.objects.active = obj
 print(obj.name)
 bpy.ops.object.editmode_toggle()
 bpy.context.object.data.uv_textures['LightMap'].active = True
 bpy.ops.uv.smart_project(angle_limit=66, island_margin = 0.02)
 bpy.ops.object.editmode_toggle()

python

Some Edits

• The collection bpy.data.objects is all objects in a blend file,
  whether linked to context scene, another scene or no scene. If not in
  the context scene cannot be the context object. Use scene.objects
  


• I put the "convenience variable" context in test scripts, so I can
  paste later into panel or operator code where it is passed as a
  parameter to most methods, in which case better not to use path addressing from bpy IMO it gets tedious reading bpy.context.object.data.uv_foo.bar.blah
  


• Add a UV map named "LightMap" if the mesh doesn't already have one.


• Blender uses radians not degrees as the native unit of rotation.

Script

import bpy
from math import radians

context = bpy.context
scene = context.scene

for obj in scene.objects:
 if (obj.type == 'MESH'):
 scene.objects.active = obj
 obj.select = True
 print(obj.name)
 lm = obj.data.uv_textures.get("LightMap")
 if not lm:
 lm = obj.data.uv_textures.new("LightMap")
 lm.active = True
 bpy.ops.object.editmode_toggle()
 bpy.ops.uv.smart_project(angle_limit=radians(66), island_margin = 0.02)
 bpy.ops.object.editmode_toggle()
