Gridline Blueprints — Graphs That Think Straight.
Orthogonal wire routing for Unreal Engine Blueprint graphs. Cleaner graphs, smarter connections — built for the way engineers think.
Every tangled wire in your graph is focus spent tracing instead of building. Gridline Blueprints replaces Unreal's default wire routing with a precision orthogonal system — wires run in straight lines, turn at right angles, and actively route around the things in their way. This isn't just straight wires.
It's a complete routing pipeline.
✦ Core Routing
Orthogonal paths — wires route horizontally and vertically only, with configurable Pin Length and Bend Position (Source or Destination bias)
Short Wire fallback — short connections automatically use smooth splines or straight lines instead of awkward right-angle stubs; configurable via Short Wire Threshold
U-turn resolution — backwards wires are handled cleanly with a dedicated routing pass, not just bent in place
✦ Wire Spacing
Automatic parallel spacing — overlapping wire segments on the same axis are spread apart by a configurable Spacing Distance, so every connection stays readable
✦ Node Avoidance
Simple mode — shifts the wire's vertical segment horizontally to clear node boundaries
Complex mode — adds extra routing segments to fully navigate around nodes, handling tightly packed graphs and tall nodes
Configurable Avoidance Padding on all sides
✦ Corners & Junctions
Three corner styles: Eased (Bézier arc), Fillet (quarter-circle arc), or Chamfer (straight diagonal cut)
Four junction styles: Break (gap in the passing wire), Jump (arc over the crossing), Ring (circle outline), or Disc (filled circle)
Configurable Corner Size and Junction Size
✦ Reroute Nodes
Hidden reroute nodes — reroute nodes become invisible and appear as seamless wire bends; they reappear on hover for selection and manipulation
Named Reroute nodes — a two-node system (Declaration + Usage) for tagging a wire with a persistent name and color, then re-tapping that value anywhere in the Blueprint. Declarations capture a value; Usage nodes read it back. Linked by a stable GUID that survives renaming, copy/paste, undo/redo, and Blueprint recompilation
Named Reroutes show up in the Blueprint action menu, support Jump to Definition, and work across graphs within the same Blueprint
Context menu conversions — right-click to convert between standard Reroute and Named Reroute nodes in either direction
✦ Flow Animation
Animated Dot or Pulse indicators travel along wires to visualize data flow direction
Filter by: Execution wires only, Data wires only, All wires, or Selected node wires only
Configurable Animation Speed, Animation Spacing, Animation Size, and Pulse Brightness
✦ Appearance
Wire Thickness multiplier (0.5× to 5.0×)
