BlueLine Smart Tagging & Node Alignment 5.7 is a lightweight, modular C++ plugin for Unreal Engine 5 designed to address three key challenges in professional development workflows: Graph Readability, Team Collaboration, and Data Visualization.
It improves graph readability by replacing messy Bezier "noodles" with clean stubs and rerouted node wiring—without the performance overhead of A* pathfinding. The plugin introduces "Soft Magnet" formatting (via Shift + Q), which aligns selected nodes to a grid relative to their input connections, without reorganizing the entire graph. This selection-based approach ensures that only the chosen nodes are modified, preserving the developer's layout and preventing large Git or Perforce diffs, thus maintaining clean commit histories.
For team collaboration, BlueLine provides consistent, shared visual styles through a Data Asset system. Gameplay Tags in the Details Panel are displayed as colored "chips" instead of plain text, with team-wide color synchronization achieved via a BlueLineThemeData-derived Data Asset. Users can define tag styles (e.g., Status.Debuff with a red color) and configure whether children inherit those styles.
The plugin supports both C++ and Blueprint workflows. In C++, developers can use the static library to render colored tags in the HUD or world space during runtime debugging, ensuring visibility even during Play In Editor (PIE) sessions. In Blueprints, a "Draw BlueLine Debug Tag" node is available for visual debugging.
Available at GitHub (https://github.com/gregorik/BlueLine) for core OS versions (v0.1+), and featuring full FAB versions (v1.0+) with advanced modules, optimizations, and dedicated support, BlueLine enhances workflow efficiency and team alignment in Unreal Engine 5 development.
