VF Render Lottie

EARLY ALPHA VERSION - Renders polygons as animated shapes to the Lottie JSON format.

This is intended for a very specific and limited workflow. Please refer to the Python-Lottie Blender plugin on GitLab for more general purpose use cases.

Installation

• Requires the Lottie library for Python to be installed inside Blender

   import subprocess
   import sys
   subprocess.call([sys.executable, "-m", "ensurepip", "--user"])
   subprocess.call([sys.executable, "-m", "pip", "install", "--upgrade", "pip"])
   subprocess.call([sys.executable,"-m", "pip", "install", "--user", "lottie"])

• Requires element attributes set in Geometry Nodes

  • Color attribute set to Face with name Lottie_Fill_Color

• Current testing is at the one polygon stage; trying this on an actual mesh will likely crash everything

Features

• Takes current active mesh object and for each polygon creates a new shape, sampling positions for every frame in the Blender timeline, and outputting everything as a .json file using the Lottie Python library
• Supports render variables from VF Autosave Render + Output Variables
• Supports custom path input for future integration with VF Delivery
• Converts Blender linear colour values to sRGB values during export
