with Weave project files 'weave_start.py' and 'weave_done.py' :

running scripts on Blender v4.0.2 causes:

  File ".../weave_done.py", 
  line 307, in create_emissive_material
  KeyError: 'bpy_prop_collection[key]: key "Emission" not found'

code currently reads:

  307     material.node_tree.nodes["Principled BSDF"].inputs["Emission"].default_value = color

changing the input name to "Emission Color" fixes this error

 307     material.node_tree.nodes["Principled BSDF"].inputs["Emission Color"].default_value = color

typos in the file :
subdivided_triangulated_cube_part_1_start.py

line 19 :
... see this from more

line 47 :

thx for sharing

have fun

Do you know why the left side of the monkey's left eye is always black after running this code? Didn't I replace the color of 500 faces?

The sequence_editor_stitched_together_clips_done.py works when I paste the code in GUI, have the Video Editor open and hit run. When layout is open or when or running from command-line using blender.exe -b -P sequence_editor_stitched_together_clips_done.py, it gives this error:

File "C:\myProjects\myBlender\sequence_editor_stitched_together_clips_done.py", line 91, in create_transition_between_videos bpy.ops.sequencer.movie_strip_add( File "C:\Program Files\Blender Foundation\Blender 3.4\3.4\scripts\modules\bpy\ops.py", line 111, in __call__ ret = _op_call(self.idname_py(), C_dict, kw, C_exec, C_undo) RuntimeError: Operator bpy.ops.sequencer.movie_strip_add.poll() failed, context is incorrect

How can I modify the code to avoid this. In other words, how can I choose the Video Editor context inside the code.

(I'm using Blender 3.4)

several project startup files have errors in Blender v4.0, as with Weave, for example:

.../weave_done.py", line 209, in set_scene_props
TypeError: bpy_struct:
   item.attr = val: enum "Very High Contrast" 
      not found in (..., 'AgX - Very High Contrast', 'AgX - High Contrast', ...)

this is fixed by changing

209    scene.view_settings.look = "Very High Contrast"

to

209    scene.view_settings.look = "AgX - Very High Contrast"
