⚡ Async Load Toolkit — Async Asset Loading, Anywhere in Blueprint

Async Load Toolkit gives Blueprint the full power of Unreal's streaming system — progress, cancellation, priority, batching and memory control — without a single line of C++.

Drop the plugin in your project and call LoadAssets from anywhere: an Event Graph, a Blueprint Function, a Macro, an Interface. Every request returns a storable Handle you can poll, cancel or re-bind at any time, and the built-in reference counter keeps your assets alive exactly as long as you need them.

Vanilla Blueprint gives you a single fire-and-forget node that only works in the Event Graph, with no progress, no cancel, no batching and no protection against GC. Async Load Toolkit fixes all of it.

📦 LOADING

• Load a single asset, an array of assets, or soft class references

• Batch loading on every supported engine version — no Asset Manager setup required

• Typed loaders — StaticMesh, SkeletalMesh, Texture2D, Material, Sound, AnimSequence, Niagara, DataAsset, Widget Class — no manual casting

• Synchronous fast path — if assets are already in memory, the callback fires the same frame

• Explicit synchronous loaders included, clearly marked, for the cases where you want them

🧩 CALLABLE ANYWHERE

• Delegate-based functions work in Blueprint Functions, Macros and Interfaces — not just the Event Graph

• Classic async nodes with On Completed / On Progress / On Failed pins for Event Graph use

• Bind any Custom Event as the completion callback via Create Event

🎛️ FULL CONTROL

• Storable Handle object — keep it in a variable, poll it, pass it around

• Real progress 0–1 and loaded/total counts — drive any loading bar

• Cancel in-flight requests at any time

• Three priority levels for queue ordering

• Optional timeout with typed failure reportin

🧠 MEMORY & PERFORMANCE

• Reference-counted Retain / Release — assets stay loaded until every system releases them

• Automatic protection against post-callback garbage collection

• Request deduplication — identical or in-flight requests join the existing handle instead of reloading

• Chunked throttling — load thousands of assets in controlled batches with a flat memory footprin

⚙️ QUALITY OF LIFE

• Set Static Mesh Async / Set Material Async — load and apply in one node, safe against destroyed actors

• Spawn Actor Async from a soft class reference

• Query helpers — Is Asset Loaded, Get If Loaded, Are All Loaded

• Project Settings for global defaults (dedup, fast path, chunk size, timeout)

🔍 DEBUGGING

• In-game debug overlay listing every in-flight request

• Console commands — AsyncKit.Debug, AsyncKit.DumpRetained, AsyncKit.CancelAll

• Optional request logging and synchronous-load warnings

⚠️ Important Notes

• Async nodes with multiple execution pins can only be placed in Event Graphs — this is an Unreal Blueprint compiler restriction, not a plugin limitation. The delegate-based functions are provided precisely for Functions, Macros and Interfaces.

• Asynchronous loading means your logic continues immediately. Anything that consumes the loaded assets must live in the callback, not after the

  loading node.

• Synchronous loaders block the game thread by design and will hitch. They are included for deliberate use and are clearly marked.
