🚀 SceneProgExec: Blender Python Script & Package Manager

SceneProgExec is a command-line tool and Python module that enables seamless execution of Blender scripts and package management within Blender's isolated Python environment.

🔥 Features

✅ Execute Python scripts inside Blender
✅ Install Python packages in Blender's Python environment
✅ Perform a full reset (remove all third-party packages)
✅ Works both as a CLI tool and a Python module

📥 Installation

1️⃣ Install from PyPI

pip install sceneprogexec

OR Clone the Repository

git clone https://github.com/KunalMGupta/SceneProgExec.git
cd SceneProgExec
pip install .

2️⃣ Set Environment Variables

Before using SceneProgExec, set the required environment variables:

export BLENDER_PATH=/Applications/Blender.app/Contents/MacOS/Blender
export BLENDER_PYTHON=/Applications/Blender.app/Contents/Resources/5.0/python/bin/python3.11

To make this permanent, add the lines to your ~/.bashrc or ~/.zshrc:

echo 'export BLENDER_PATH=/Applications/Blender.app/Contents/MacOS/Blender' >> ~/.zshrc
echo 'export BLENDER_PYTHON=/Applications/Blender.app/Contents/Resources/5.0/python/bin/python3.11' >> ~/.zshrc
source ~/.zshrc

Important! In case running this inside a linux container install the following dependencies:

apt update
apt install -y libx11-6 libxi6 libxxf86vm1 libxrender1 libgl1 libxfixes3 libxkbcommon-x11-0

3️⃣ Run CLI Commands

Once installed, you can use sceneprogexec globally.

🛠️ Usage

🔹 Run a Python Script Inside Blender

sceneprogexec run my_script.py --target my_scene.blend

✅ Runs my_script.py inside Blender.

🔹 Install Packages Inside Blender

sceneprogexec install numpy pandas

✅ Installs numpy and pandas inside Blender’s Python.

🔹 Install Packages With a Hard Reset

sceneprogexec install numpy pandas --reset

✅ Removes all third-party packages before installing new ones.

🔹 Reset Blender's Python (Remove All Third-Party Packages)

sceneprogexec reset

🗑️ Deletes all third-party Python packages in Blender.

🏗️ Using as a Python Module

SceneProgExec can also be imported and used in Python scripts:

from sceneprogexec import SceneProgExec

executor = SceneProgExec()
executor.install_packages(["numpy"])
executor.run_script("my_script.py")
executor._delete_all_third_party_packages()  # Hard reset

script = """
import bpy
print("Hello, World!")
"""
executor(script, target="test.blend")

🚀 Automatic Cleanup

• Temporary directory (blender_tmp) is deleted after execution.
• No leftover logs or scripts clutter your system.

🛠️ Troubleshooting

❌ Blender not found?
Ensure BLENDER_PATH and BLENDER_PYTHON are correctly set. Run:

echo $BLENDER_PATH
echo $BLENDER_PYTHON

❌ Permission denied?
Try:

chmod +x /usr/local/bin/sceneprogexec

❌ Blender script fails to execute?
Check the log:

cat blender_tmp/blender_log.txt
