Scripting in Blender

Snippets

Execute script

# nexss
# NORE: Blender render does not allow for custom arguments (-- but for now it is not implemented in nexss PROGRAMMER), you need to pass it through pipe eg. or in _nexss.yml in data section.

echo {"ObjectName": "NexssEdit"} | nexss Blender

# In Blender
blender --background --python myscript.py
blender myscene.blend --background --python myscript.py

import bpy
import os

filename = os.path.join(os.path.dirname(bpy.data.filepath), "myscript.py")
exec(compile(open(filename).read(), filename, 'exec'))

Loading Script as module

import myscript
import importlib

importlib.reload(myscript)
myscript.main()

Adding search path

import sys
import os
import bpy

blend_dir = os.path.dirname(bpy.data.filepath)
if blend_dir not in sys.path:
   sys.path.append(blend_dir)

import myscript
import importlib
importlib.reload(myscript)
myscript.main()
