Summary0005192: Crash while cooking a bound Material with Texture2D parameters
Description
  • Add custom binding in Unreal for UMaterial
  • Add Texture2D parameters
  • Cook
  • Crash

[Inline Frame] UnrealEditor-NoesisRuntime.dll!Noesis::Ptr<Noesis::BitmapSource>::{ctor}(Noesis::BitmapSource ) Line 29 C++

Made some local changes to the UE runtime to try and isolate the erorr, it seems to be the AddReference call in Noesis::Ptr<BitmapSource> ctor.
Currently discussing with our IT team if we can safely upload the crash dump but I can post some investigations:

NoesisCreateTypeClassForUMaterial in NoesisTypeClass.cpp

NoesisCreateComponentForUObject seems to create a valid Ptr<BaseComponent>
StaticPtrCast<BitmapSource>( createdComponent ) calls through to AddReference which it can't seem to find. Looks like it can't find the virtual function in the vtable, looking at disassembly to see what it 's doing.

Got a fix locally by adding this code to NoesisCreateComponentForUObject. It seems like UTexture2D was falling into creating a NoesisObjectWrapper which was failing the static cast into BitmapSource. Adding this special case to use NoesisTextureWrapper instead fixes the cook crash
