Hello people, I want to open the load window file browser during Run Time with the blueprint. How I can do this ?
try this thread:
this is possible but not with stock Blueprint nodes. the engine dialog (IDesktopPlatform) is editor only and dies in packaged builds, so a lot of old answers that point at it dont actually survive packaging.
what you want is a runtime dialog: OS file window with the game viewport as parent, async so rendering keeps going, path string back on the game thread. then whatever loader matches your file type takes it from there.
zero C++ route is Async Runtime File Dialog, a native file picker plugin for Unreal Engine 5. Open File Picker as one Blueprint node with multi-select and runtime filters, packaged Win64, 5.0-5.8: Async Runtime File Dialog — Native OS File Picker for Blueprints | Fab
