In this post we explore two ways to run a python script from Photoshop providing arguments (like the Photoshop file name). Those simple scripts helped us create complex behaviours to process results of Photoshop scripts for the Set department of the feature film Dilili in Paris or in our recent project for the Lodève Museum. The background artists could work in Photoshop and start those procedures without exciting software. Using such scripts to push previews to the production manager software, moving files, starting a blender playblast to get a preview of the updated scene, etc. Saving a lot of time.
In a previous article we shared our way of organizing the files. In this one, we’ll introduce you to the use of a simple python library called Lucidity, very useful to start handling your project naming conventions. The aim is to quickly check if your file paths are correct, or build paths from a set of variables, without coding your own parser.

In this article about installing third-party python libraries, we go deeper when installing with pip is not enough and you need to compile the library.
EDIT 2020: This series is now obsolete since Blender 2.80. Please see this answer on StackExchange. Here is a possible function to install modules inside Blender, provided you can modify the Blender directory:
import subprocess
def install_pip_dep(module_name):
python_path = bpy.app.binary_path_python
subp = subprocess.run([python_path, "-m", "ensurepip"])
if subp.returncode != 0:
return False
subp = subprocess.run([python_path, "-m", "pip", "install", module_name])
if subp.returncode != 0:
return False
return True
if __name__ == '__main__':
install_pip_dep("triangle")
In this article, we share some tips to install third-party python libraries for your scripts and add-ons. This is the easy way, when the library exists on repositories accessible to package managers such as pip.
