What It Means & How to Fix It
🧠 Why You’re Seeing This Error
C2672 means you’re calling a function (especially a templated function), but the compiler can’t find any overload that matches your arguments.
In UE5, this often pops up when:
- Using
Cast<>,SpawnActor<>,CreateDefaultSubobject<>, etc., with wrong or missing template parameters - Passing wrong types to templated functions
- Forgetting to explicitly declare the template type
💥 Example Error Message
error C2672: 'Cast': no matching overloaded function found
🛠️ Example Code
AActor* MyActor = Cast(SomeObject); // ❌ Missing template argument
✅ How to Fix C2672 in UE5 – Step-by-Step
✔️ 1. Explicitly Provide Template Parameters
Fix:
AMyActor* MyActor = Cast(SomeObject); // ✅
✔️ 2. Make Sure the Argument Type Matches
Unreal’s Cast<> only works on UObject* types.
Wrong:
Cast(FVector()); // ❌ FVector is not a UObject*
✔️ 3. Verify Argument Count and Template Usage
If you’re using UE functions like SpawnActor or CreateDefaultSubobject, double-check their full signature and required template arguments.
✅ Summary: How to Fix C2672 in UE5
| Cause | Fix Example |
|---|---|
| Missing template argument | Use Cast<AMyClass>(Obj) or SpawnActor<>() |
| Argument type doesn’t match | Only use with UObject*-compatible arguments |
| Using wrong overload | Check function signature and parameters |
