Penrose Triangle Building - Paradox Toolkit
sketchfab
Here's a sample scene created using the Paradox Toolkit addon for Blender 2.8. Take your time to study it thoroughly, and I recommend checking out the YouTube tutorial on how to harness the power of this amazing tool. You can download the addon from my GitHub repository, where you'll find all the details you need to get started. The base figure that serves as the foundation for this scene is a Penrose Triangle.
