Get SubstringUE 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7updated 2mo agoWhy: UE5's main message just says how many errors occurred, not what they are. The actual errors live in the Errors panel. Fix: Open the Blueprint editor. Click Window menu → Errors Panel. Expand each entry to see specific node locations. Use the Errors panel's hyperlinks to jump straight to the broken nodes. Fix from top to bottom — often one fix cascades to clear several others.
