Open Logic is a Unreal Engine plugin designed for creating custom visual scripting graphs with custom nodes. It seamlessly integrates with the editor and supports shipping builds for game integration.
Originally, this plugin was sold on the Unreal Engine Marketplace from April 2022 to March 2025. However, I’ve decided to remove it for several reasons - primarily because I no longer have the time to maintain it. Rather than letting it fade away, I believe open-sourcing it on GitHub is the best way to give it a proper conclusion.
I’m incredibly grateful to everyone who supported me during this journey and purchased the plugin. Your support meant a lot.
This was my first plugin and my first real experience with C++, so there are some questionable design decisions and a few unfinished features (e.g., the Wildcard type). Still, the plugin mostly works and can hopefully serve as a useful reference or starting point for others.
