Editor
Steps to Reproduce
- Set NumCustomDataFloats to 1 on ISKM component;
- Call SetCustomData or SetCustomDataValue on any freshly added ISKM instance;
- Returns true;
- Get said added ISKM instance, call GetCustomData on it;
- Returns true;
- The output CustomDataFloats length will always be 0 because it returns an empty array.
*Besides, forgetting to set NumCustomDataFloats (e.g. add 1 value to CustomData but forget to set Num to >0) crashes the engine.
Expected Result
GetCustomData array should return the numInstances*CustomData entries added accordingly. In any case, it shouldn’t return an empty array.
Observed Result
GetCustomData returns an empty array no matter what.

Additional Notes
Engine/Source/Runtime/Engine/Private/Components/InstancedSkinnedMeshComponent.cpp
Manually pre-sizing the array to GetNumCustomDataFloats() before calling the native TArrayView overload returns the correct data.
