Advanced Ledge System on Unreal Engine 5 Only Blueprints - Part 07
In this live build we push the ledge system to a production-ready feel: we add medium-distance traversals, build a readable debug overlay, randomize animation variations, and smooth out attachments with smart transform saving and tuned delays. Everything is done in Blueprints, step by step, and aimed at indie devs and intermediate Unreal learners.
Most Valuable Lessons and Insights
Make sure your debug is on by default: a simple Debug Light System boolean plus on-screen prints for reach distance and the chosen montage makes testing fast and clear.
Make sure angles and distances gate the logic: use Is Angle Within Range with a forgiving window like −20 to 20 and clamp medium reach to around 70 units up; longer moves use larger thresholds.
Make sure montage selection can vary: add a second montage slot (for example LeftMid2) and feed both into a Select node with a random index to add natural variation.
Make sure attachment feels AAA: save the actor transform before playing the montage and tune a per-montage Delay Until Correction so the timeline starts correction at the right moment.
Make sure to avoid hidden engine glitches: never duplicate a structure asset for a new tier; recreate it fresh if you need a new version. If things look wrong, Validate Assets and rebuild the structure.
