Hi , The version Rebuilt binaries for promoted changelist 2444381. 2 days ago build for EDITOR and IOS in dev mode
When we add the TrackGenerator folder → Buleprint Splines Track from your samples in the editor this BREAK In file → K2Node_CallArrayFunction.cpp Ligne 42
D:\UnrealEngine4\SRCs\UnrealEngine-promoted\Engine\Source\Editor\BlueprintGraph\Private\K2Node_CallArrayFunction.cpp
UE4Editor-BlueprintGraph.dll!UK2Node_CallArrayFunction::PostReconstructNode() Line 42 C++
The Blueprint Track sample work with 4.7 but we can’t test the build because we have not GitHub sources as describe https://github.com/EpicGames/UnrealEngine/tree/promoted#branches we should test with promoted that should be the more stable…
Same problem of Array than before with last 4.8.0 … Hope this help to fix so we can test if we can ship on apple …
